Chia Cultivation

Chia is easy to grow, beautiful to look at, and offers lots of nutritional value. It deserves a place in any garden. I have been growing chia organically for the past ten years, and in that time I have fine-tuned my growing and harvesting techniques. Chia is one of the easiest plants to grow, and one of the healthiest.

Chia seeds are a very high source of linolenic acid (LNA) and linoleic acid (LA). Both these essential fatty acids attract oxygen and help cell membranes to be flexible and fluid, plus strengthen our immune system to help protect our bodies from viruses, bacteria, and allergies.

Most people's diets are dangerously low in essential fatty acids, which results in tired muscles, fatigue, and a range of health problems. We need to eat EFAs daily because the human body cannot manufacture them. If your diet includes a lot of refined oils and processed foods, you are most at risk. EFAs, such as those found in chia, can assist with weight loss and removal of toxins from the body. Enzymes in chia also help with the digestion of other foods.

Traditionally, chia has been used to calm nerves and strengthen the memory, but the most high-profile value of chia comes from the seed's ability to give you energy. University research has revealed that one tablespoon of chia seed could reasonably be expected to sustain a person working hard enough to work up a sweat, for 24 hours.
10 Ways to Use Chia Seeds and Leaves
Chia is very convenient and versatile. Here are ten different ways to use chia seeds and leaves.

1. Chew Chia Seeds
I chew chia seeds, releasing their nutty taste, as a snack on a busy day. They swell a little as they absorb saliva, making them soft and ready for the journey to your stomach.

2. Soak and Drink
Soaking the seeds first in water or fresh juice makes them even easier for your body to digest. Wait long enough for the seeds to swell. Chia seeds have appetite suppressant qualities and are useful for dieters.

3. Add Chia to Milkshakes and Smoothies
If you enjoy a summer smoothie or your kids like milkshakes, add some chia seeds for extra energy. You probably won't notice them as you drink, but the goodness will be there!

4. Sprinkle Chia Seeds Over Food
Chia seeds can be sprinkled over breakfast cereals, jam on toast, or a nice fresh salad. When I serve my home-made pumpkin soup, I add a dollop of sour cream and sprinkle chia seeds over the top of each bowl.

5. Eat Chia Sprouts
Sprouting chia seeds increases their vitamin content and makes them even more nutritious. Just like sprouted alfalfa and mung beans, chia sprouts are a great addition to a salad.

6. Drink Chia Tea
The leaves, fresh or dried, make a relaxing and therapeutic tea. Chia tea has traditionally been used for fevers and pain relief, to relieve arthritis and respiratory problems, as a gargle for mouth ulcers and sore throats, and to reduce blood pressure and cholesterol levels. If you want to sweeten your chia tea, use a healthy sweetener like honey or stevia.

7. Add Chia to Bread Mix
When baking bread, I sometimes toss a handful of chia seeds in the mix. This is not the healthiest way to eat chia because essential fatty acids are at their best when uncooked, but it makes the bread a little lighter and provides a nice change in texture.

8. Use Chia to Feed Birds and Animals
Extra chia leaves I feed to my hens, pigs, or other animals. The animals would eat the seeds too, but I keep most of the seeds for human consumption and planting next year. If I've had a bumper crop, I feed chia seeds to my chickens and other birds.

9. Chia as Garden Mulch
If you don't have animals, use the chia leaves as mulch. Remember though, if you have not removed all the seeds they are likely to grow where they fall. To avoid random chia plants growing in your garden, add the leaves and stalks to your compost heap.

10. Give the Gift of Chia
Home-grown chia makes a wonderful gift. Package seeds in a jar or bottle for those who like to eat chia, and give one of your small plants to anyone who likes to garden.

Here are some hints to remember:

Don't clear existing weeds until you are ready to fill the space.
When it's time to plant, work gently. Don't dig up or turn all the top soil (thereby exposing a whole new lot of weed seeds).
Plant your new seeds in the freshly cleared space without inviting unnecessary competition from deeper weed seeds.
Add mulch and compost and anything you like to make your garden healthier as your plants grow, but put it on top and let it feed the soil from above.

If you wait until the flower head browns, you risk losing the seeds.

Begin harvesting your chia as soon as most of the petals have fallen off the flower.
Give the heads time to dry in paper bags or on a drying rack. Expect at least some of the chia seeds will break free in the process.
Do not hang the plants upside down in your shed.

Nutritional Value of Black, White, and Brown Chia Seeds: Which Color Is Best?
Chia seeds come in various shades of brown, gray, black, and white. In fact, the accepted definition of "black chia" includes gray and brown chia seeds. Yes, it has always been the case with chia that brown is black. (In name, at least.) Black chia has traditionally been the name given to any chia seed that isn't white (which, incidentally isn't really white, either).

I was warned that since commercial cloning has resulted in the production of darker seeds, PR teams were generating controversy around the "superior nutrition" of black chia, making the darker seeds seem more valuable and (hopefully) undermining the status of natural chia. So if you ever hear anyone claim that black chia is better, think again.

It came as no surprise to me that when I googled the subject of black and white chia seeds being the only ones suitable for consumption, dismissing the value of brown seeds, the one and only company making that claim about brown chia seeds is—you guessed it—the very same chia company I'd been warned about.

It seems the word of doubt is starting to spread, but don't believe what they tell you—the brown seeds are in no way inferior (and, in fact, their brown color may be a sign that they're natural!). Folks who simply repeat what they read on the internet will fall for the PR stunt but those who know about chia, through research and personal experience, will always know it is a load of hogwash.

People can—and will—grow chia in their yards, with varying levels of success. Whether they plant black, white, or brown chia seeds from whichever packet of chia they have in their cupboards makes no real difference.

The 10 biggest advantages of vertical farming

It’s now possible to produce large and consistent quantities and quality of food using revolutionary vertical farming methods. But are there enough indoor farming advantages to make it the future of modern agriculture?

In this article, Cambridge HOK examines why vertical farming could have a big role to play in the future of global food production.

1. Reliable year-round crop production
The biggest vertical farming benefit is the fact it’s not dependent on the weather – meaning you can achieve a consistent year-round crop production without worrying about the impact of adverse weather conditions can have both on quality and profiling of production and yield.

Farming in a protected, well-monitored and managed environment brings assurance and peace of mind for growers providing repeatable programmable production.

By eliminating the effects of mother nature, there’s no such thing as a 'seasonal crop' and growers won’t suffer from losses as they try to push the production windows of ‘seasonal cropping’.

They can also successfully reduce harvest times and improve volume without compromising on flavour or quality, which always remains 100% consistent. Indeed, flavour and shelf life have consistently been able to demonstrate improved attributes when using an indoor vertical growing system, when designed and managed correctly.

This allows commercial growers to confidently commit to the delivery schedules and offtake agreements demanded by their customers.

2. Unaffected by adverse weather conditions
Growing in a fully enclosed and climate-controlled environment completely eradicates the need to rely on - or worry about - the weather.

Whereas crops in a field can be ruined by excessive rain, wind and drought (or pests!); vertical farming provides 100% harvest certainty.

3. Better use of space
It goes without saying that traditional farms need fertile arable land. But vertical farms can be designed and built in any climate or location - irrespective of weather conditions or temperature extremes.

And because their stacking grow systems allow them to expand upwards, it’s also possible to achieve higher productivity on a small land area.

Depending on which crop is grown, one acre of vertical farm could consistently grow the equivalent to between 10 or 20 soil-based acres.

4. Minimise water usage
One of the main vertical farming benefits is that the Hydroponic growing process only uses about 10% of the amount of water, and as a result the nutrients and fertilisers, compared to traditional methods. Because the water is clean after usage, it also allows it to be recycled and reused, reducing costs and minimising waste.

5. Environmentally friendly
Indoor farming can be good for the environment because it massively reduces the amount of fossil fuels needed for farming equipment which is not required to sow, fertilize, weed or harvest crops.

Vertical farming also helps to improve biodiversity because it does not cause land surface disturbance, which helps the natural animal population which lives in and around farms to thrive.

6. No chemicals or pesticides
Growing food in a vertical farm, when managed correctly offers the opportunity to completely eliminates the need for pesticides - as pests cannot enter the controlled environment to cause crop damage and fungal diseases struggle to gain a foot hold as humidity levels are managed.

The end result is a product which is better, healthier, safer and featuring dry leaves which are clean and ready to eat.

7. Reduce transport costs
When it comes to food production, the last-mile delivery is usually the most expensive part of the supply chain. And it’s not uncommon for crops to be shipped across continents and oceans.

Growing food closer to where the consumer lives is a massive vertical farming benefit as it can massively reduce transportation costs, CO2 emissions and reduce the need for refrigerated storage – making produce fresher and more profitable.

8. Highly energy efficient
Whilst the use of LED lighting requires a significant amount of power to achieve optimum growth, vertical farms can also generate power.

Cambridge HOK specialises in renewable technologies and combined heat and power (CHP) solutions which can harness excess energy to be reused elsewhere in your business or transferred back to the national grid.

9. Safe for staff
Traditional farming has gained an unwanted reputation for being a workplace fraught with health and safety risks. With no heavy machinery or chemicals used for indoor farming, it obviously does not boast the same occupational hazards - significantly reducing the risk of injury.

10. Low labour costs
Fully automated indoor growing systems do not need huge amounts of manual labour to achieve successful year-round production. People with low-level skills are still required to sort and pack harvests, but labour overheads will remain low – even if production is scaled upwards.

Lemongrass – cultivation, benefits

Lemongrass is a tall, perennial grass native to the tropical and sub-tropical climates of South East Asia and Africa. India is the highest producer of lemongrass, where it is cultivated along with the mountain range of the Western Ghats(Maharashtra, Kerala), Karnataka and Tamil Nadu states and beside the foothills of Arunachal Pradesh and Sikkim in the Himalayan mountains.

The so-called East Indian lemongrass (Cymbopogon flexuosus) , also known as Malabar or Cochin grass is native to India, SriLanka, Burma, and Thailand; for the related West Indian lemongrass (C. citratus ), a Malaysian origin is generally assumed. Both species are today cultivated throughout tropical Asia.

The Lemongrass oil is distilled from leaves and flowering tops of Lemongrass. The oil has a strong lemon-like odor, due to a high percentage ( over 75%) of citral in the oil. The characteristic smell of oil makes its use in scenting of soaps, detergents, insect repellent preparations.
Lemongrass characteristics
Lemongrass is a multiyear crop, which can be used for 5 years.
Lemongrass grows around 1.8 meters (6ft) in height.
Leaves are long, green, linear tapering upwards and along the margins.
Lemongrass is a tropical plant that freezes to death where winter temperatures drop below 15F (-9C)
Lemongrass oil benefits
Lemongrass (Cymbopogon citratus) oil has many therapeutic uses below are few
Lemongrass oil is beneficial for scenting soaps, detergents and insect repellent.
Consumption of Lemongrass tea aids digestion.
The presence of Citral in Lemongrass oil is used for perfumes, cosmetics, and beverages.
lemongrass adds flavoring for culinary purposes.
Lemongrass oil is also used as an insect repellent ingredient in sprays, candles, soaps, and aromatherapy.
Lemongrass oil has anti-bacterial and anti-fungal properties.
Lemongrass oil makes a good preservative.
Lemongrass oil is good for Stomach and intestinal cramps, High blood pressure, pain and swelling, Cough, Fever, Common cold and Vomiting.
Cultivation of Lemongrass
Lemongrass is very easy to grow and requires low maintenance. a complete guide from soil preparation to the harvest of Lemongrass is shared below:

1. Soil Selection for Lemongrass cultivation
Soil should be porous. Preferable red soil with a mix of sand.
Water retention of soil should be low, clay soil is not suitable.
Rains should be around 200-250cm per year.
It requires a lot of sunlight and warmth.
2. Sowing period
The slip of lemongrass which has well-developed roots should be sown directly.
No transplanting is required.
12000 to 15000 lemongrass slips are required for the one-acre plot.
Each lemongrass slip costs 3Rs.
The best time to sow lemongrass is between June – August.
Sow at a distance of 45*45 cm
3. Irrigation for Lemongrass cultivation
Watering is not necessary during rainy days.
Water the plants once in 15-20 days. 
It requires a low amount of water.
Suitable for dry areas and water shortage areas.
It requires a lot of sunshine, and less rain around 200-250cm per year.
4. Weeding procedure in Lemongrass cultivation
Initially after sowing Lemongrass once or twice before the first harvest.
Later weeding should be done, after every harvest.
5. Harvesting Lemongrass
The complete crop above the ground can be used to extract the essential oil.
The percentage of citral will determine the quality of Lemongrass oil.
Harvest the crop from 10 to 15 cm above the ground. Leaving the plant to regrow.
The first harvest is after 6 months when it is fully grown.
Successive harvests will be after every 3 months for the next 5 years.
10 ton to 14 ton herbage from an acre per harvest can be expected. (10 -14 ton/acre/harvest)
There are 3 to 4 harvests per year.
6. Lemongrass Essential Oil extraction
The extraction of this essential oil is done by steam distillation of grass.
The distillation process should be done for 3 hours to extract complete Lemongrass oil.
Start oil extraction only after 24 hrs of harvest, as the water content will reduce the moisture content by 30% and improves oil yield. Do not let the herbage to dry in direct sunlight, keep in shade.
7. Aromatic Oil Production from Lemongrass per acre
In 1-ton herbage 8kg – 10kg of essential oil can be extracted.
So per acre in a year around 120kg – 150kg of essential Lemongrass oil can be extracted.
8. Purification of Lemongrass oil
The insoluble particles present in the oil are removed by a simple filtration method after mixing it with anhydrous sodium sulfate and keeping it overnight or for 4-5 hours.
9. Storage and Packing of Lemongrass Oil
The oil can be stored in glass bottles or containers made up of stainless steel or aluminum or galvanized iron, depending upon the quantity of oil to be stored.
The oil should be filled up to the brim and the containers should be kept away from direct heat and sunlight in cool/shaded places.
GC report for Lemongrass Essential Oil
Gas chromatography (GC) is a common type of chromatography used in analytical chemistry for separating and analyzing compounds that can be vaporized without decomposition. There should be a peak for Citral, this determines the quality of Lemongrass Oil quality. The purity oil determines the rate in the market. After every oil extraction process, the GC certificate is a must for that batch, to command a better price.
We can always save the cost of Lemongrass slips as its expensive for more than one acre of land. A small amount of planning can bring down costs. Sow slips in a quarter of an acre, 4 to 6 months prior to actual sowing. By now the lemongrass will grow and have a lot of slips in the single plant. Each plant can produce more than 100 slips. This can be transplanted to the larger field.
Lemongrass cultivation profit on an average for consecutive 3 years are ₹55000, ₹190000 and ₹190000. Farmers can earn a stable income through Lemongrass cultivation. Most of the water-scarce locations are well suited for Lemongrass cultivation. The demand of Lemongrass oil is an all-time high, as it has a long list of benefits and spread across the market.
Lemongrass Diseases
Lemongrass is a sturdy plant, but still, sometimes it may get affected by some diseases. Few of the common diseases are listed below:
Red Leaf Spot :-Brown spots with concentric rings in the center appearing on the lower surface of the leaves. The spots may be formed on leaf sheaths and midrib. Later the spots merge to form bigger patches and the affected leaves dry away.
Leaf Blight:- Minute, circular, reddish-brown spots mostly on the margins and tip of the leaves which merge to form elongated reddish-brown necrotic lesions resulting in premature drying of leaves, older leaves are more susceptible to infection.
Little Leaf or Grassy Shoot:- Stunted growth Little leaf formation in place of the normal inflorescence.

Cultivation Technology of Chamomile Plant

The commercial essential oil of chamomile is known as Blue oil and it is obtained from its shade dried flowers by steam distillation. German chamomile is botanically known as Matricaria chamomilla L, apart from this species two other chamomile species found in the world, i.e. Roman or English Egyptian chamomile and Moroccan chamomile. It is used in perfumery as well as medicinal importance like face creams and sun burn and flavoring fine liquor.
As medicine, the plant possesses antispasmodic, antichloristic and attenuate properties. Extract of chamomile is also useful in stomach disorders, cure of ulcer and healing of wounds. Flowers are extensively used as herbal tea and it is very common in china. The plant is native to Europe and has been used in folk and traditional system of medicine in Europe and Arab for thousands of years.In India, the plant was introduced by Arabs and has been grown on limited scale around Lucknow for more than three hundred years. The estimated world production of chamomile is about 20,000 tonnes of dried flowers and 7 tonnes of oil. 
In India, the plant has been cultivated for the production of dried herb, known as “Babuna”, and the flowers, known as Gule Babuna in trade. The drug is prescribed by the practitioners of Unani system of medicine in the country.

Improved cultivation and distillation technologies of chamomile were developed by R&D institutions. In the beginning of nineteen, large-scale cultivation of German chamomile was taken up by private growers for the purpose of export of flowers and oils to European countries. In India, cultivation was started in about 40-50 ha. of land with annual production of 30-40 tonnes of flowers. Being a highly labour intensive crop, it is ideally suited for cultivation in eastern Uttar Pradesh and Bihar.

Soils and Climate Suitable for Growing a Chamomile Plant:

It can be cultivated in wide range of soils, except those which are light textured and have low water holding capacity. The cultivation of chamomile has been done successfully on medium and heavy (with high clay content) textured soil, including those of traditional rice growing soils. The plant has also been found to tolerate high degree of sodic soil and hence the soils with pH 8.50 or 9.0 can successfully be utilized for this cultivation.
Soils with high water table during winter season do not support good plant grows very well in moderately cool weather. It can be cultivated as winter crop in plains of north India and as summer crop in the hills of J&K, Himachal Pradesh and Uttar Pradesh. The best growing conditions for the plant are 30-32°C temperature and 40-50% atmospheric humidity. Growth and flower bud formation is severely affected when the temperature reaches 38° C and above.

Propagation of Chamomile:

Chamomile is propagated by seeds for commercial cultivation of crop, in some of the European countries root cuttings are also used. Although, direct sowing of seeds in lines can be done to raise the crop, planting for the commercial production is recommended through raising of seeding in nursery. Raised nursery beds of 4 x 1 or 5 x 1 m are prepared by mixing good amount of farmyard manure or compost in the soil. About half to one kg seed, depending upon the germination percentage, is considered sufficient for raising nursery for planting one ha. land.
Since, it has been observed that the germination percentage of the seed vary from year to year, it is always better to plant 10-20% more area under nursery than actually required quantity, so that the nursery does not fall short for planting the targeted area. Before sowing, seeds are mixed with 8-10 parts of sand the spread over to the beds uniformly. Seeds are properly mixed in the soil by hand or with some tool. While incorporating the seeds in the nursery, it should be ensured that they are not placed beyond 1 cm. deep in the soil. Sprinkler irrigation is applied immediately after sowing.

Thereafter, beds are surface irrigated with slow discharge of water. Sowing of nursery is done in the first 10-15 October in planes and in hilly areas it is recommended in the month of March. In nursery beds, seeds take 3-5 days for germination and seedlings become ready for planting in the final field after 4-5 week after sowing of nursery. After 3 weeks, nitrogen @ 20 kg/ha is recommended for top dressed in nursery beds for better results.

Planting of Chamomile Seeds:

After 3-4 weeks, full grown seedlings are uprooted and planted in the final field. The recommended distance of lines are made 25-30 cm. apart and 10-15 cm plant to plant. After planting, the field is flood irrigated with slow discharge of water, so that seedlings are not washed away or uprooted with irrigation water. Delay in the irrigation may cause wilting and death of seedlings in final field.

Manures and Fertilizers Application to Chamomile Plant:

The plant of chamomile has been found responsive to fertilizer application, particularly nitrogen and phosphorus. Nitrogen, phosphorus and potassium in the ratio of 35:30:20: kg/ha. is incorporated in the soil as a basal dose. Depending upon the fertility of the soil, 2-3 top dressings each with 25 kg nitrogen is done. The first top dressing is made after 35-40 days after planting and third after first picking of flowers.

Irrigation Requirement for Chamomile Plant:

For better plant growth, soil moisture should be maintained at optimum level throughout the growth span. After flowering starts, the crop is irrigated as fortnightly interval to keep the soil moist. Prior to flowering, irrigation at 3-4 weeks interval may be sufficient. Thus, for successful crop production 5-6 irrigation is required.

Picking of Flowers:

Picking of flowers is most important and laborious operation in chamomile cultivation. Therefore, the plant is cultivated in areas where sufficient labour force is available at cheaper rate. In sub-tropical climate of north-India, plant starts flowering in the 20th Feb. and continues up to 20th April. During this period 5-6 pickings are done at 10-12 days interval. In most of the chamomile growing countries picking of flowers is done by the family members, especially the women and children.
A person can pick 8-12 kg of fresh flowers in a day (8hrs) which on drying may weigh about 2 kg. In large scale plantation the picking is done on contract basis of the quantity of flowers gathered by them. Only the fully developed flowers are picked (buds and fully matured flowers contains less of essential oil). In India, laborers are paid at the rate of Rs.3.00 – Rs.4.00 per kg of fresh flowers picked by them.

Drying of Flowers:

The fresh flowers of chamomile contain 70-80% water. The picked flowers are immediately transferred to the drying shed and spread over to ground in very thin layers of 1-2 cm, and allowed to dry till flowers loose 45-65% moisture. At this stage flowers can be dried in thick layers to make available the space for drying of fresh collected flowers. Artificial dryers may also be employed where such facilities exist.In India, the drying is done in thatched huts, having several racks made of bamboo or other locally available material. The flowers are spread on the racks over cloth or thin gunny bag, to allow proper aeration and quick drying. By applying these methods, a farmer can be able to retain the original colour of flowers. In absence of proper drying, the colour of flowers turn to brownish or black, such flowers give very poor oil yield in distillation.

Distillation for Extraction of Oil from Chamomile:

Steam distillation method is appropriate for extraction of oil from dried flowers of chamomile, because the flowers require high pressure which can be managed only with the steam distillation. The Cohobation process is applied for improvement of the recovery of oil as certain constituents of oil are soluble in water.Chamomile oil forms crystals and has a tendency to form a deposit and revolves inside the condenser. Therefore, it is advisable to stop the flow of cool water (distillate) into the condenser from time to time, so as to raise the temperature of condenser and to reliquary the oil deposits on the wall of condenser as well as separator.

Oil Content and Yield:

The average crop may yield 35-45 quintals fresh flowers/ha within the period of 3.5 months, which on drying gives 9-10 quintals dry flowers. The yield of flower may vary depending upon the fertility of soil, management practices and numbers of picking of flowers. A good managed crop may yield as high as 18-20 quintals dry flowers. The essential oil (blue oil) content in flowers varies from 0.15-1.1%, and largely depends upon the variety grown and the conditions of drying of flowers applied.

Uses of Chamomile Oil:

The oil has warm herbaceous hay like odor with fresh-fruity undertone. In fresh distilled oil sometimes odor is animalic sweet while in aged oil the odor is pleasant with sweet tobacco warm like.It is used in fragrance for imparting mellow tone. It is also used in men’s fragrances (though in low dosages) particularly colognes. It imparts a warm rich undertone which lasts throughout the stage of evaporation.It is also used in flavour for mellowing the effect of synthetic ingredients, particularly in tobacco. The use level is upto 1%. It is also used in baked goods and candy flavours.It does have very vast application in aromatherapy as well. It is analgesic anti-allergic, anti-inflammatory, bactericidal, fungicidal. It is used in skin care for acne, burns, earache/eczema & dermatitis. Also used in hair care. Effective in Arthritis, muscular pain, joint pain & rheumatism. Also used for headache, nervous tension, migraine and stress related conditions.

Sarpagandha Plants Cultivation

Sarpagandha (Rauvolfia serpentina) is used in Ayurveda , Unani and folk medicines as well as in conventional western medicine. This plant is also known as Indian Snakeroot; in Sanskrit as Sarpagandha, Chandrika, Sarpakshi , Patalguruda; in Hindi as Chandrabhaga, Chota-chand, Sarpagandha; in Assamese as Arachoritita; in Bangla as Chandra; in Kannada as Sarpangandha, Sarpagandhi, Shivanabhiballi, Sutranavi, Patalagandhi; in Malayalam as Churannavilpori, Suvapavalporiyam; in Marathi as Harkaya: Harki; in Tamil as Chevanamalpodi; and in Telugu as Patalaguni, Patalagaruda, Sarpagandha.
The plant contains a number of bioactive chemicals, including ajmaline , deserpidine , rescinnamine , serpentinine , and yohimbine . The alkaloids in the plant reduce blood pressure, depress activity of central nervous system and act as hypnotics.
The useful parts are roots and leaves. According to Ayurveda the root is bitter, acrid, sharp, pungent and anthelminic. Rauvolfia preparations are used as antihypertensive and as sedative. It is also used in the treatment of various central nervous system disorders associated with psychosis, schizophrenia, insanity, insomnia, and epilepsy.

Market Potential : The natural reserves of this plant are declining as a result of over-harvesting especially after reports of its medicinal properties appeared in the literature. International Union for the Conservation of Nature and Natural Resources (IUCN) has kept this plant under endangered status. Importers , buyers within the country, processors, traditional practitioners, Ayurvedic and Siddha drug manufacturers throng the markets for procurement of this plant every year. Its domestic demand is quite large. As the production is much less in India , the internal market itself is highly potential.

Basis and Presumption :

The agricultural land and related infrastructure is available with the entrepreneur.
Prices are calculated as per the prevailing market rates.
The yields depend on proper implementation of package of practices.
Economics of cultivation greatly improves on scale of operation.
This activity provides tax-free high returns. Additionally a number of government support schemes are available. Latest provisions need to be checked up.
Market for medicinal plants is volatile and economics may vary from time to time.

Agri practices : Sarpagandha is an erect perennial shrub with a long, irregularly, nodular, yellowish root stock. The leaves are long, lanceolate and bright green in colour. They are borne on stem in whorl of three. The flowers are pink or white and are found in clusters. The fruits are small, globose; initially greenish purple in colour but eventually turning blackish when ripe. Flowering time is March to May in Indian conditions.

Soil & Climate : The plant prefers soil with plenty of humus and rich in nitrogenous and organic matter with good drainage. Alkaline soils are not suitable for commercial cultivation. The sandy loam to medium black cotton soils rich in organic matter with pH 6-8 and good drainage facility are suitable. It grows in a wide range of climatic conditions but flourishes well under hot humid tropical climates in open or partial shade. Elevations of 1300 m having a temperature range of 10-38oC and annual rainfall of 2500 mm are suitable to this species. Good yield is obtained in areas less prone to frost and having less severe winter.

Land Preparation : The land is ploughed deep in May and left for weathering. After pre-monsoon showers FYM is added followed by second ploughing and two cross harrowing to break the clods. The land is finally dressed by planking and beds are laid out. Nursery should be raised in a partially shaded area with adequate irrigation facility. Each bed should be about 1.5m wide, 150-200 mm high and of convenient length. Beds with shallow furrows 80-100 mm apart are prepared in April and irrigated.

Propagation :

About 5-7 kg seeds are required for sowing one hectare area. Fresh seeds are preferred for sowing as their viability lasts for only 6 months. It has been observed that the seeds stored for more than a year are difficult to germinate. Therefore it is essential that seeds collected between September to December should be used for planting in the following season. Seeds are treated with Thiram (2-3 g / kg seed) after soaking in water for 24 hours and sown from the end of April to the first week of May at a distance of 8-10 cm and 1-2 cm deep. These are covered with a mixture of FYM and soil and irrigated daily. Germination is complete in 30-35 days. The germination rate varies from 10-50 per cent.
It can also be propagated by vegetative means using stem and root cuttings and root stumps. Root cuttings 30-50 mm long and not exceeding 125 mm diameter are planted in June- July and are covered completely with the soil leaving only 10 mm above the surface. The cuttings sprout within 3 weeks if there is good moisture. Success rate is 50-80 % and around 100 kg of root cuttings are required to plant one hectare area. Stem-cuttings 150-200 mm long with 3-4 nodes are planted in the nursery in June and kept moist until they sprout. Cuttings treated with IAA (30 ppm) initiate rooting in 15 days. The success rate obtained in stem cuttings is about 65%. In case of root stumps, approximately 50 mm roots with a portion of stem above the collar are planted in May- June in irrigated fields. Though around 90-95 % of success is obtained in this method, only one plant can be raised from a single stump.
Seedlings, 40 - 50 day old bearing 4-6 leaves, are ready for transplantation in the first week of July. These seedlings are uprooted and treated with Bavistin 0.1% for 30 minutes and then transplanted at a distance of 450 x 300 mm in the main field. This is followed by a light irrigation. Around 10-15 % of the seedlings are retained for gap filling 10-15 days after planting.

Fertilizer : Generally organic cultivation is practiced. Before sowing 10–15 tonnes of farm yard manure/ha is used. In the nursery, FYM (1/3rd of recommended dose) along with 2/3rd of soil mixed with 10 % B.H.C @ 20 kg per hectare is required. 30 kg Nitrogen and 30 kg each of Phosphorus and Potash per hectare are required. At the time of planting, 1/3rd of Nitrogen and the entire dose of Phosphorus and Potash are applied 450 mm away from the rows and 70-100 mm deep. 50 days after planting 2/3 rd Nitrogen is applied and the remaining Nitrogen is top dressed in the next rainy season.

Irrigation

Nearly 15-16 irrigations are required. Irrigation is required twice a month during hot dry season and once a month in the winters.
Sarpagandha being a long duration crop and slow in growth in the initial stages can be intercropped. Vegetables like brinjal, cabbage, okra and soybean may be planted in Kharif

Weed Control : Two weedings in the first year and one weeding in the second year followed by one hoeing usually at the beginning of the growing season are required. Flowers appearing on very young plants should be nipped to promote root growth.

Pest control : The major pests appearing on this crop are moth, grub, black bug and weevils. Grubs can be controlled by mixing BHC 10 % with the soil at the time of land preparation, whereas caterpillar, black bug and weevils can be managed by spraying Asataf 10g / 10 L of water. Diseases like Leaf spot, Anthracnose and Dieback are known to cause damage to this crop. Leaf spot and Dieback can be controlled by spraying 0.2% Dithane Z-78 or DM-45 in early June before monsoon and repeat the spray at monthly intervals until November. Anthracnose can be controlled by spraying Blitox 50WP @ 40 g in 10 L of water.

Harvesting : The crop is ready for uprooting after 18 months of planting when the alkaloid content is maximum, i.e. 1.4%. It is irrigated 8-10 days prior to uprooting and the above ground foliage is cut and roots are taken out 5.0 Post harvest operations

Drying : The roots are cleaned, washed and dried in shade till the moisture content reduces to about 8%. As the outer skin contains about 80% of the total alkaloid, the skin should not be damaged while cleaning the roots. Brown to black coloured seeds, which appear from August to December are collected and soaked in water for 15-20 hours and rubbed with hands to remove seed coat. The seeds are washed thrice and dried. Dried seeds are stored in moisture proof place for next sowing. The weight of 100 seeds is about 3.5-4 g.

Yield : Average yield per acer is 2000 kg dried roots and 200 kg seeds.

Economics of one acer sarpgandha cultivation Expenses :

What are Morels?

every kilogram of morel would cost between 20,000 and 40,000, depending on its quality and harvest.

Everything You Ever Wanted to Know about Morel Mushrooms
What are Morels?
Morels are one of the most desired wild mushrooms in the world. They are not farmed like most grocery store mushrooms, Cremini, Portobello, Oyster, etc. but gathered in the wild. The part that we eat is the fruiting body of the underground organism called mycelium that has a complex symbiotic relationship with trees. Every spring mushroom enthusiasts, foraging chefs, and an ever growing group of commercial harvesters hunt these little forest treasures.

The Morchella genus has been the subject of fascination and debate for centuries. Mycologists (mushroom scientists) cannot agree on how many subspecies of Morchella there are and the nomenclature is constantly under revision. However, doesn’t “a rose by any other name would smell as sweet?” Everyone can agree that morels are delicious and nutritious.

What do Morels Look Like?
Morels vary tremendously in appearance. Their shape can be oblong to bulbous. Their color can be blonde to grey. Their size can be smaller than your fingertip to larger than your hand. Their most identifiable characteristic is what’s typically described as a honeycomb like exterior. Bees are are more methodical though. The ‘combs’ or pits on the outside of morels can be tight or loose and form an imperfect pattern. The inside of morels are hollow and white’ish and up close you can detect a goosebump-like texture. The base of the cap joins to a white’ish stem which can be short or tall and the hollow of the cap runs continuous into the stem (this is important to distinguish it from some false morels).

Why are Morels so Popular?
They are delicious. Even people who say they don’t like mushrooms often fall in love with morels. These people generally find the texture of mushrooms slippery, slimy, or otherwise off putting. Morels are unique with their meaty texture and an earthy and nutty flavour.

They have a big reputation. Morels are a bit of a rock star in the food world because they’re so hard to find, so expensive, and so exotic looking. They are usually reserved for fancy meals with fancy wine and meats.

Why are Morels so Delicious?
Words can only go so far. As described above they are earthy and nutty, woodsy and toasted. The flavour is deep as opposed to strong and distinct without being weird. Their texture is meaty but in a tender way. Certainly a satisfying morsel of protein but not squishy or chewy. Morels don’t offend palates or overpower dishes, and yet they stand above and apart. Every bite of a meal with morels is the best bite.

Are Morels Good for You?
Absolutely. Morels are loaded with all kinds of nourishment not listed by the required nutrition facts table of Canadian Food labels. As morels tend to grow in rich soils they come packed with vitamins and minerals. While the nutrition can vary based on the soil they are found in, morels will generally contain significant amounts of Iron, Copper, Manganese, Phosphorus, Zinc, Vitamin D, Folate, Niacin, Riboflavin and a decent dose of Potassium, Magnesium, Calcium, Selenium, Thiamine, Vitamins E and B6.

Morels are also loaded with antioxidants, balance blood sugar, and repair liver-damage. Plus, they are high in protein and fibre.

Why are Morels so Expensive?
Morels are not farmed. The complex, symbiotic relationship that the morel mycelium have with trees is difficult to replicate in an artificial environment. It is frequently attempted, even at the commercial level, but if there were a truly reliable method to cultivate morels, global supply would have increased, demand would drop, and the wild morel industry fall apart.

This means that every morel that you eat has been picked by hand in its natural environment. And most likely that someone has traveled a great distance, hiked a great deal, perhaps camped remotely for weeks, battled the elements (mosquitoes, horseflies, rain, drought, etc.) and somehow managed to get that delicate specimen back to the city in decent condition for you to be able to purchase.

[UPDATE: Since the writing of this page China has developed techniques to farm morels. There is debate as to their quality and taste (consider the difference between farmed and wild salmon). This will surely have effects on the global morel market over time].

Where can you Buy Morels?
Starting mid to late spring you may find dishes at high-end restaurants that have a touch of fresh morel. You may see fresh morels at farmers’ markets or high-end grocery stores but they deteriorate quite quickly. If properly managed they keep for about a week. The vast majority of morels are dried, this a good thing, and the majority of dried Canadian morels are exported. Global supply for morels rarely meets global demand and other countries are willing to pay top dollar. Domestic consumption for wild mushrooms is low in Canada and the U.S relative to Europe or Asia but is on the rise. Increasingly, you are able to buy dried morels at the retail level and if you you have a connection, you may be able to purchase them buy the pound.

Harvesting Morels
“Morels are everywhere and impossible to find” as the expression goes. Hunting morels can be an occasional hobby or a seasonal trade. For a beginner forager, learning from someone who knows is the surest and easiest way to acquire the skill.

Starting out
If you don’t have the opportunity to learn directly from someone, start by getting intimate with nature every spring, as the tree buds appear. It’s amazing how much you learn one year to the next. Take a journal and a camera so you can reference and build on your experiences. Follow harvesters in your area on twitter or instagram so you know when they are out picking and so you can look for similar soil conditions, trees, and topography. Join a mushroom foray or a mycological society if you can find one. Just like anything it takes practice. If you need confirmation from a book or a chef, you are not ready to eat your finds. When you’ve seen morels up close in their natural environment, picked them, handled them, and sliced them, you won’t hesitate to eat them.

“There are old mushroom pickers and there are bold mushroom pickers, but there are no old-bold mushroom pickers”

Safety
If you are picking remotely, you should have some back country skills. It is advisable that you never pick alone and you should always have a GPS and satellite phone (if you are very remote). Always have water, snacks, a lighter, a first aid kit, bug spray, and bear spray.

Picking in urban or industrial areas is arguably more dangerous. Do not pick mushrooms by heavy traffic, waste disposal sites, or any heavy industrial processing. It is also advisable to avoid picking mushrooms from orchard or farmland unless you know they are organic. What’s in the soil will be in the mushrooms.

Cutting
It is best to cut the morel with a knife an inch or less of the stem. The stem is totally edible and delicious, it is simply not industry standard to have a very long stem and the longer you go the more likely it will be dirty, sandy, gritty. If you pluck, your mushroom will be dirty and frayed.

Carrying
Don’t squish your morels by placing too many on top of eachother. Place them in baskets or buckets with holes drilled into them so the mushrooms can breathe. It’s also nice to cover your basket with a cloth or towel so needles and other debris don’t get in.

Storing
Fresh morels keep for about a week refrigerated, depending on the condition you found them in. The wetter and hotter they are, the more quickly they will deteriorate. Worms can certainly be an issue. If you don’t pick any wormy ones to begin with, you’ll protect the rest of your haul from getting wormy during storage. Place them in the fridge, no more than a few layers deep, with plenty of air to circulating around them. Drying is an excellent storage option. More on that topic below.

What Makes Morels Grow?
Morels are the reproductive organ of the underground mycelium. The mycelium develops its fruiting body when it is stressed or when the spring sap movement brings energy and carbohydrates to the tree. The stress reaction of the mycelial net is usually brought on by soil disturbance whether it be from fire, excavation, beetle kill, wind throw, cattle, orchards, etc. The sap movement is a good condition for the mycelium to give birth to its babies.

When do Morels Grow?
Morels are one of the few spring species of mushrooms. In Canada, you want to start looking in April (on the west Coast) or May (in the prairie). If living elsewhere, often a good indicator is when the tree buds show signs of blooming. If conditions stay favourable we can pick into mid and occasionally late summer. This usually means travelling north or up in elevation. A flush on the prairies or flatlands will be brief and intense and may come only once. A season in the coniferous mountains may extend through the summer as the sun, rain, and winds combine to provide flush after flush of mushrooms.

Where do Morels Grow?
In the industry, we refer to morels as either naturals or fire morels. The naturals grow in pastures, meadows, and orchards. There may be just a couple or there may be bucket-fulls. They may come one year, or for many consecutive years, and then disappear without any obvious reason. Fire morels, will often grow abundantly the spring following the previous summer’s forest fire. The preference is for a July/August fire. A fire doesn’t guarantee you’ll find morels the following year but it’s a good start. Other conditions such as heat, rainfall, sun exposure, elevation all influence the crop as well. Fire morels like pine, and spruce, but if you are in a burn, look on the outer edge, or for patches where the trees are not charred, we call this the soft burn. They like where the needle bed is reddish and are often in between tree roots or the shade of fallen timber. You won’t have much luck where regrowth has taken off, that is where the ground has already ‘greened up’. The more mosquitos biting the more likely you are to find morels.

Which Morels Can you Eat? (and are there ones you can’t?)
‘True morels’, that is all morchella genus are edible and incredible when cooked. Morels are not to be eaten raw or consumed in large quantities because they contain a mildly toxic substance, which is destroyed in cooking. It is possible for some people to have an allergic reaction to morels. As with all new food, if you are consuming it for the first time a moderate amount is recommended.

There are also ‘false morels,’ which is a term referring to morel look alikes such as the verpa genus and the more distant gyromitrae genus. A skilled mushroom picker could confidently distinguish themò as clearly as a cucumbers vs zucchini. Slicing the specimens in half reveals a lot of helpful information.

hollow, oblong like interior that sits on top of a hollow stem is morchella
relatively longer stem that holds a cotton-like tissue and is attached interiorly to the ceiling of the cap is verpa
a stem that is enveloped by a series of brain-like folds and with an exterior that is less honeycomb like and more wrinkle like is gyromitra
There is ongoing concern and debate about the edibility of ‘false morels’. Verpas are more commonly considered safe, although must be properly prepared. There have been toxic reactions and fatalities reported on gyrometrae, which have great regional variation, but they are considered a delicacy in some countries where they are consumed widely with no ill effect. Again, proper preparation is essential. We certainly don’t advise experimentation and after two decades in the mushroom industry, we still stick morchella.

Is Picking Morels Sustainable?
Absolutely. It is like picking apples off of an apple tree. The tree will continue to thrive, many apples will fall to the ground and rot, and perhaps one of the thousands of apple seeds will eventually yield a new tree. The mycelium is like the tree, but it is underground so you don’t see it. When you harvest morels, just as when you harvest apples, there is no damage to the mycelium just as there is no damage to the tree. A huge amount of the morels never get picked but just disintegrate in the bush, alone 🙁 Unlike apple seeds though the spore of the mycelium are barely visible, come from multiple places, and are airborn, therefor travel like smoke in the wind. Don’t worry about the mighty spore getting around folks.

Are Fresh Morels Better than Dry Morels?
Some say yes, we say no.

Fresh morels are fragile. They may crumble when handling, cleaning, and cooking. They cook more quickly and have a slightly more delicate texture. Their flavour is a little more musty or exotic. Fresh morels will keep about a week if conditions are ideal.

Dry morels are easy to handle. They rehydrate quickly, they do not crumble, they are much easier to stuff (if your’re chef’y like that). They are also cleaner. When you dry a morel they contract a little, causing sand, dirt, pine needles, poplar fuzz, moss, or other bits of nature to fall off. When you rehydrate them, any remaining bits of nature fall to the bottom of your soaking liquid. When using your soaking liquid in your dish, leave the last few tablespoons in the bowl. When you dry a morel you concentrate the flavour, think of raw fresh nuts versus roasted nuts. The flavours are quite different. When dried in the sun, the morel absorbs additional vitamin D, like the human skin, and most of us could use a little more of that. Dry morels can be enjoyed all year long.

Time and time again, when eaten fresh and dried with our fellow harvesters out in the bush, dried is the clear winner. It’s a treat to eat fresh because it’s only possible for a short time each year, but there are food snobs that age their dry mushrooms like wine. Drier and older better? We think so, but decide for yourselves.

How are Morels Dried?
Drying morels is a bit of an art. The components are time, air flow, and heat. If you are lucky, it is warm and sunny enough that you can let the sun do most of the work. Just lay the morels on screens, with plenty of airflow, and rotate them occasionally. If it rains, or it is cool, or you are drying large quantities, you’ll need to get much more involved. We let the sun work first and we finish with wood heat in a portable commercial drier. The product has a lovely wood aroma and flavour, and we can do a large batches that meet food safety standards. Be careful about drying too hot or too fast. You’ll cook the mushroom and you’ll end up with something that is difficult to rehydrate with less flavour. With experience, you learn to adjust the heat, airflow, and drying times to what each batch of mushroom requires.

How are Morels Reconstituted (rehydrated)?
While drying morels is a bit of an art, reconstituting or rehydrating morels is so easy a 3 year old could do it (as long as the mushrooms were dried properly to begin with). Add some water from the tap and wait a few minutes. Pinch them every now and then and when they are plump they are ready to use.

Milk Thistle - Silybum marianum Cultivation

Cultivation and Post-Harvest Technology of Milk Thistle (Silybum marianum).

Milk thistle (Silybum marianum is a medicinal plant cultivated in Parts of UP, Rajasthan, Punjab, Haryana, Tamilnadu, Gujarat and Madhya Pradesh. It is an important medicinal plant used by man from ancient times. Milk Thistle is an herbal supplement that detoxifies and protects vital liver functions and positive effects on the liver and gallbladder. The seeds contain the highest concentrations of the active compound, silymarin. Silymarin is an antioxidant that reduces free radical production and oxidative damage. It may also inhibit the binding of toxins to the liver. In animals, silymarin reduces liver injury caused by acetaminophen and has been shown to have positive effects on alcoholic liver disease, hepatitis and toxin-induced liver problems. Milk thistle has been used for over 2,000 years as a natural treatment for liver disorders. This plant is a spiny nature so can be very easily grown where cattle or other grazing animals are a problem. 

Introduction Milk Thistle is an erect annual or biennial growing up to 115-125 cm tall. The stem is pale-green, simple or slightly branching, the leaves are large, mottled with white, pinnatified into ovate, triangular, sinuate-toothed spiny lobes. The head are globular, 6-10 cm broad and concave at the base. The outer scales of the involucre are oblong, broadening into an ovate, prickly, cellate margin appendage which tapers abruptly into a long spine; the inner scales are lanceolate and entire. The flower are hermaphrodite and fertile, purple or white, the tube is slender the limb is dilated below and five-fold. Different plant parts of Milk thistle have been used from the last 2000 years in the preparations of various traditional medicines. It has been used for the treatment of diseases like liver cirrhosis, jaundice, hepatitis and liver poisoning. The flowering heads are good for diabetics. The other medicinal uses of Silybum are anti-cancer, anti-depressant, anti-oxidant, cardio protective, demulcent, tonic, hepato-protective, hepato-regenerative, immuno-stimulatry and as a neuroprotectiveSoil and Climate It can be grown on a variety soil, but thrives best in well-drained sandy loam to clay loam soils containing a moderate amount of organic matter. Any soil which is saline, alkaline or water-logged is unsuitable for its cultivation. A range of 200 c to 250 c of maximum temperature accompanied with fairly good winter rainfall appears to be conducive to better vegetative growth of the plant. Milk thistles prefer sunny or lightly shaded areas..
Land Preparation It being a shallow rooted crop does not require deep village. The preparation of land is usually not as fine as for other cultivated crops. One or two ploughing is necessary. 10 tonnes/ha of well decomposedfarm yard manure is applied before ploughing the field for getting a good growth and applied irrigation for sowing of seeds.Varieties Only two improved varieties developed by CSIR-Central Institute of Medicinal and Aromatic Plants Lucknow Viz., CIM-Liv: This variety was developed by CIMAP in 2005. It was developed through half-sib progeny selections. This variety is having more number of capitulum with high seed yield of 9 q/ha and Silymarin content 2.8 %. CIM-Sil 9: This variety was developed by CIMAP in 2013. It was developed through population improvement. It is dwarf in height, seed yield is 10-12 q/ha and Silymarin content is 8%. Cultivation Planting time and seed sowing: The crop is raised by using the seed obtained from the previous season’s crop. It is sown during September-October in the plains and March-April in hilly areas. The plant should be raised by sowing the seed proved more helpful for efficient cultural operation. 2-3 seeds are placed in loosened soil at the desired inter and intra row spacing and later covered with soil. One and a half to two kg seeds would be sufficient to stock one hectare of land. After the seed is germinated thinning is done, one healthy seedling is kept and rest are removed and utilized elsewhere to fill the gaps, though sowing in situ proved to be best. Transplanting method can also be used if the land to be stocked is not vacant at the time of sowing of seed. The sowing of the seeds should be started from November and can be extended up to January. Under cultivated conditions flowering commences in the second or third week or February and continues till the end of March. Thus it is advisable to sow the seed in early November, so that plant gets sufficient time for attaining optimum vegetative growth and see yield.Spacing:Recommended spacing of 60 cm x 30 cm is ideal for better growth, optimum yield and also conductive cultural operations. Minimum plant to plant distance should be not less than 35 cm. it can also be sown at 60 cm x 60 cm spacing using a seed-drill.Irrigation:First light irrigation is followed after one week of seed germination. Minimum 10 irrigations would be required during the active growing period of the crop. Irrigation at the time of flowering is essential. Manures and fertilizer:The crop responds well to the application of manure and fertilizers. FYM at the rate of about 10-12 t/ha should be added at the time of land preparation. In addition, a dose of 120 kg N, 100 kg P2O5and 75 KG K2O/ha, is recommended for obtaining a good yield. Nitrogen is applied at the rate of 60 Kg/ha in the form of urea in two splits, first dose being applied three weeks after germination followed by second dose one month before flowering, i.e., mid-January or first week of February and whole dose of P and K are applied at the time of planting in row by placement method .Weeding:Milk thistle is often called a weed itself, and is a very good competitor. Hoeing and/or hand weeding in the early stages is the only requirement. One or two weeding when the plants are young will help to avoid competition from weeds.Diseases and pest:Milk thistle is not bothered by many pests and no diseases have been noted. However there is a report of the pest Tanyameu spolliatus which can be controlled by a spray of 0.03% Methyl Parathion. Among the diseases root-wilt caused by the Rhizoctonia species has been observed under Karnataka condition which can be controlled by drenching the soil in fungicides like Captan or Brassicol (0.1%).
Post Harvesting Technology Harvesting:Milk thistle is a 110 to 120 days crop. Flowering is initiated inthe third week of February and goes on till the plant withers in May. The thistle heads grow into full size within 30- 40 days. The harvesting of thistle head is to be done when about 50 per cent of these have grown in full size indicated by withered petals. Delay in harvesting may cause seeds shedding resulting in heavy loss. Usually two harvesting are made, first in the second week of April followed by another in May. If harvested at the right time, on an average, about 1 t/ha of seeds may be obtained.Drying:The material kept in open sun for about 5 to 7 days dries completely. The dried material which consists of ruptured heads, dry sticks and leaves is beaten with long sticks to separate seeds from the heads. During the beating, the dry material should be kept covered with gunnies or any other cloth so as to arrest the spread of pappins which create great nuisance if allowed to float in air. The seed and extraneous material are separated through sifting and winnowing. A further drying seed for a day or two is recommended before the material is finally stored.Processing:The fluffy pappus must be removed from the "seed" (achenes). The seed is usually dried, powdered and made into a tincture using ethyl alcohol. Since silymarin is nearly insoluble in water, aqueous extracts or teas are ineffective for liver treatment. It is best to use 95% alcohol to extract the seed. Most of the silymarin is concentrated in the protein layer of the seed husk (pericarp). The tincture should be bright yellow, indicating the presence of the resinous fraction which contains the silymarin.Chemical Composition Silymarin, Silyhermin, Neosilyhermin A and B, Quercetin, Kaempferol, Dihydrokaempferol, Luteolin, Triterpene acetate, Fumaric acid and Apigenin. Conclusion Milk thistle has high medicinal value in the world and is also the number one recommended natural herb for liver health. The achenes, i.e. fruits of the plant, are commonly used as a medicinal drug; they are the raw material for isolation of different substances with liver-protection activity In fact, in Europe, Milk thistle is a prescribed medication and also extracts of milk thistle is prescribed to treat mushroom poisoning, alcoholic cirrhosis, chronic hepatitis and acute viral hepatitis and cultivation of milk thistle also gave more economic returns to the farmers.

Agarwood Plantation

Are you thinking or worried about how to do agarwood plantation and cultivation? This article helps you to set up and maintain the agarwood plantation and cultivation.
Agarwood also known as Oud has been extensively used for making several valuable products over decades. Agarwood is a resinous heartwood that naturally occurs in the Aquilaria trees that commonly grow in the Himalayan foothills of South Asia and in the rainforest of Papua New Guinea. Though Aquilaria tree, the most important source of agarwood is commonly found in countries such as India, Malaysia, and Thailand, its globally increasing demand makes agarwood farming the choice of many people these days.

Agarwood Plantation

Since the Agarwood tree can grow on a wide range of soil and under diverse conditions, cultivation of this valuable incense has not been a concern for farmers. Agarwood tree is planted mainly during the beginning of rainy season. Agar is mainly formed inside the trunk or root of the tree when it gets infected by Phaeoacremonium parasitic fungus. The precious resin formed is a result of the tree's natural defense mechanism during the fungal infection. This resin often referred to as Oud or agarwood, is the major component in the fragrances. In oud plantation, the planter would inject artificial inducer into the xylem of the tree for the early production of Agarwood. The interesting fact is that natural resin that usually forms after around ten years can be done in a short period of time with the help of this inoculation technique. Resinous wood will be formed in the roots, trunks, and branches of the tree after a few months. During the harvest time, to extract resin, the root will be dug out and the trunk part will be cut down 20 cm above the ground. The resins can then be separated from the white unaffected wood of the tree.
Agarwood Uses

Agarwood, the resinous wood formed in Aquilaria tree is used as incense, for extracting essential oil, medicinal purposes as well as a perfume ingredient. The precious agarwood traced back thousands of years has an interesting history and is used for treating respiratory disorders and in traditional Chinese medicines. Agarwood can also be carved into beads, sculptures, and boxes. Whether for agarwood chips, medicine, oil or fragrances, the agarwood market is growing rapidly.

If you are planning to do agarwood plantation, then you should do some research to get an expert opinion regarding Oud plantation. we are the leading Agarwood product manufacturers in India can help you with Agarwood tree cultivation and things you need to consider before engaging in agar production.

Agarwood is the most expensive agro-product in the world that is used to make lots of products such as essential oils, herbal teas, agarwood chips and tablets for incense and also accessories.

Being used in natural medicines, the agarwood oil is called as the liquid gold.

An idea of its value can be acquired by knowing a simple fact, that pure agarwood is very rare and costs more than gold, diamonds and even platinum. However, nothing is impossible and to make the impossible process of finding pure fragrant agarwood, the Agarwood Plantations in Kerala are being done.

Actually the heartwood of the tree is otherwise non-fragrant. When it is infected by the fungus, the tree produces resinous substance that is heavenly fragrant and comes with loads of health benefits. Now, in the plantations, the trees are grown and then injected with the fungus. This process is done when the trees are 5 years old and is called as the artificial inoculation.

Once the infection has set-in, the resinous deposition takes place gradually that brings huge monetary returns.

In case you are still sceptical of making a decision, then please know that agarwood tea and oils are the most expensive ones in the whole world and are consumed across the globe for various purposes.

The production methodology of the Agarwood doesn't disturb the nature or the ecosystem in any manner.

There are three methods of artificial inoculation at the Agarwood Plantations in Kerala namely – F02P (Pasting), F12S (Sticking) and F07D (Drilling and Injecting).

Once the fungus is set-in, the fungus spreads to the larger wood volume and the tree wound changes from brown to dark brown which means that the process of infection is going on. The complete process of the agarwood generation in deep trunk takes 4 to 5 years to complete.

How to Grow Black Cumin

Nigella Sativa
How to Grow Black Cumin:

After the last good frost of the winter season is the best time to plant your black cumin herb seeds outside. There are some gardeners who will grow the black cumin, also known as Nigella Sativa in several successive weeks after the final frost which is great to do if you want your harvesting season to last longer. Black cumin also make great accents to flower arrangements when their pods are dried. They are also edible as a seasoning to almost any type of food you choose to make.

Seed Sowing Depth: Your black cumin seeds should be sown in a total of about of about 8 to 10 inches in rich soil. Each seed should lay about 1/8 inch under the top layer of soil. Each seed should be planted 4 to 6 inches apart to allow for adequate growth until the plant is ready to be harvested.

It is recommended to sow your black cumin seeds outdoors after the last deep frost of the winter when at all possible. All seed should be planted in rich soil in direct sunlight for best results.

When To Sow: The black cumin seeds will do best if they are sewn right after the last hard frost of the winter so they will germinate and be ready for harvest 2 to 3 months later.

Sowing Indoors/Outdoors: Black cumin should be sewn outdoors whenever possible in soil with a pH balance of between 6.0 and 7.0. Each seed should be planted about 8 to 10 inches deep in the soil and all soil should be worked thoroughly two to three months before planting to ensure the appropriate pH balance is reached.

Plant Height & Width: The fully grown black cumin plant will end up being about 20 to 60 cm (8 to 24 inches) tall and about 2-4 inches wide when they are fully grown.

Leafs Color/Description: Black cumin does not grow with leafs but as blooms with flowers that germinate on the end when the plant is fully grown. Fully germinated flowers have light blue petals and are shaped somewhat like a star with each plant consisting of 4-5 petals on the plant.

Growth Habits: The growth habits of the black cumin flower are that they love to grow in full sunlight when at all possible. They also love rich, dark soil with a pH of between 6.0 and 7.0 to allow them to grow to be the healthiest they can possibly be. Flowers should be watered with a lighter mist or spray as they are fairly fragile avoid drenching them with streams of water which can damage the growing plant. If no rain falls, about 1-2 inches of water are needed for the plant each week and should be provided in 2 to 3 watering sessions weekly.

General Information on Black Cumin & Uses: Black cumin is often dried and used in flower arrangements and bouquets. Drying the black cumin and adding it in to a bouquet can add a nice scent as well as a pop of color and accent to the bouquet. These plants are going to need to be planted annually for such purpose as they are annual bloomers and they will not come back the next year. Drying the flowers before using them for accent is vital or they will wilt and die off within a few days.

Black cumin is also edible and can be used as an accent to foods as the seeds in their pod are completely safe and edible. Add them to your favorite dishes to add a few seeds and a little bit of crunch to your meal. Adding them to smoothies or soups for a different consistency and added health benefit is also another great idea. These seeds have a variety of edible uses including garnishes to your favorite dishes as well. Add them in and let people marvel at how well they fit in with almost anything that you plan to cook.

Pests & Diseases Black Cumin Are Susceptible Too: Black cumin is susceptible to several different issues including wilt if they are left too long and not harvested when they are meant to be. They will wilt quite quickly within a few days to a week. Be sure to harvest your black cuminon time, about two to three months after they are planted to ensure that they are being harvested before the wilt away.

Black cumin is also subject to powdery mildew during the colder months of March and April after the last frost when they are planted. Powdery mildew is a mold that will attack the plant during its growing phases when it's just starting to sprout to the point when it is just starting to flower. In severe cases of powdery mildew the plant may not be able to develop or grow and may be killed off completely.

Alternia blight is another condition that black cumin is susceptible to when the weather is hot and humid. The most susceptible stage is the stage when the plant is beginning to grow but hasn't fully reached germination and harvesting stage yet. The seeds will die by being shriveled easily as fungi take over the plant. These pathogens can be spread by clothing people wear, tools, or even the air around the plant.

The last issue black cumin can have is damping off and this condition occurs in two stages including the pre-emergence and the post-emergence phases. The pre-emergence phase causes the seeds to rot and they are usually killed before the plant even breaks the soil's surface. The post-emergence phase occurs after the plant has begun to sprout and causes the young seedlings and stocks of the plant to die off before it matures.

Harvesting Information and Storage: When harvesting your black cumin be sure to harvest the seeds by late summer. Seeds can be stored throughout the entire year. When harvesting your black cumin be sure to clip the entire flower off of the plant to ensure that all seeds and flowers that the plant has to harvest are harvested. Moreover, if you want to use the flowers for accents to arrangements be sure to cut the stems long as you will need them to ensure they fit in the bouquet.

When storing the seeds take them out of the flowers and dry them adequately before storing in air-tight bags or containers for year-around use. They are then used as accents and herbs that are spices in both your cooking and as seeds that add accents to various medicinal dishes that people create. They add great accents to dishes and awesome tastes to anything from soups to rice dishes to smoothies and back again.

If you are putting them in flower displays or bouquets be sure to dry them thoroughly before adding them to the the arrangements so they do not wilt or die before you are done enjoying the bouquet. It is best to grow new flowers to dry each year as they are brittle and may break down over time. This will keep the flowers fresh to add to your bouquets all year around. Enjoy them as a beautiful accent to any bouquet you choose to put together and ensure that they are there for you and friends to enjoy year around.
