How to Grow Stevia; Get Full Information of Stevia Cultivation in India

Stevia is a "wonder crop" with a strong sweet taste that has been used to sweeten drinks and make tea since the sixteenth century. During World War II, England started to examine stevia as a substitute for sugar, which was hard to find. But in the 1970s, the Japanese started to use stevia to replace the banned artificial sweetener, Saccharin. Currently, the stevia plant is grown in various nations around the world, such as India, China, Vietnam, Brazil, South America, South Korea, Taiwan, Israel, Argentina, Colombia, etc.

In 1971 Japan started to use stevia in its food. In 1984 China started its cultivation, in 1991 stevia was banned in the United States because of the early investigations that recommended the sweetener may cause cancer. However, in December 2008, the United States Food and Drug Administration(USFDA) acknowledged this contention, announced stevia GRAS and permitted its use in standard U.S. food production. In 2011 European Food Safety Authority approved the use of Steviol Glycosides as a sweetener and finally in 2015 FSSAI of India allowed the use of stevia in food items and beverages.

Stevia cultivation typically requires around 20 percent of the land and far less water to give a similar measure of sweetness as other standard sugars. Stevia farming gives a productive harvest to thousands of independent farmers having small lands. It does not replace food crops but is being cultivated as a cash crop on smaller plots in addition to food crops for an increase in revenue. When growing conditions are most favorable, farmers may harvest stevia several times per year.

Stevia Cultivation in India

Stevia is called by numerous names in various parts of India. Its most popular name is  "Meethi Tulsi" and "Meethi Patti". In Hindi stevia is called 'Madhu Patrika". But in most of the places, it is generally known as "Meethi Tulsi" because of its uncanny similarity to the Tulsi plant in stature, leaf shape, and other physical qualities.

Stevia is also known as Sweetleaf, Honey leaf, and Sugar leaf. Though its farming is done throughout the world for a long time, it has been around two decades when the cultivation of stevia plant was introduced in India and currently it is growing up in a great way. Currently, India has about 30 million diabetic patients, which is expected to increase to 80 million until 2025. In this way, the Indian farmers have also started to take stevia cultivation to the next level trailing the huge demand for the diabetic market here. Presently India's total annual production of stevia is about 600 tons. The weather conditions in many parts of India are very good for stevia cultivation.

Stevia Growing States in India

Maharashtra, Punjab, Karnataka, Chhattisgarh, Madhya Pradesh, and Andhra Pradesh are major Stevia growing states in India. Gradually stevia farming is picking up in Uttar Pradesh as well.

Sowing Season of Stevia

Time for sowing is February to March of the year

Soil

Stevia plants love to grow in full sun. It is grown best in semi-humid locations with acidic, well-draining soil and environments especially in hot climates. It can be grown in a wide variety of soils but it gives the best outcome when planted in sandy soil to loamy soil with a well-draining system and high organic content. Stevia doesn't grow well in saline soils as it is harmful to its proper development. The pH ranging from 6.0 to 7.5 is best for the proper growth of the stevia plant.

Land Preparation for Plantation

Before planting stevia the farmer should have to plow his land at least 2-3 times to bring the soil to a fine tilth. In his first plowing, he should mix Trichoderma with the soil and at last plowing, FYM should be mixed well with the soil.

Spacing in Plantation

Transplantation of Stevia is done on raised beds. The raised beds ought to have 12 to 15 cm tall and 50 to 60 cm in width. Row-to-Row separation ought to be 40 to 45 cm and Plant-to-Plant separation ought to be around 30 cm. This count gives Stevia plant thickness as 20,000 to 25,000 plants for every one acre of land.

Plant Population

Plant density in Stevia Cultivation should be 25,000 to 30,000 per acre when seedlings are transplanted into the main fields.

Weed Control

Hand weeding is the most common way to expel weeds from the field. First, weeding is done following one month of planting, and afterward ensuing weeding is done at regular intervals.

Irrigation

Irrigation is the most significant part of stevia farming, water is irrigated to the plants through the sprinkler system or by drip irrigation technique. The plant doesn't require water in bounty so the light water system is given at proper interims. In summer, apply the water with an interval of 8 days. Don't overwater the plants and avoid stagnation of water in the field as it will harm the harvest.

Fertilizers and Compost

Stevia needs proper balanced nutrition for appropriate development and glycoside creation. Even though stevia was initially depicted as a yield with minimal outer nutritional support requirement, however, it was found later that it reacts well to fertilizer application. The nutritional management program for stevia relies upon soil and agro climate, cultivating framework, variety, and target yield.

During land preparation, apply FYM@200qtl/acre, cow dung/urine, and vermin compost and blend well in with soil. Apply fertilizer dose of N:P:K 11:45:45 kg/acre, Urea 24 kg, SSP 282 kg, and Potash 75kg/acre to land. Apply a full dose of SSP as a basal portion. Nitrogen and Potash are applied in 10 dosages each month. The splashing of Boron and Manganese is done to give the most extreme dry leaf yield.

Application of organic compost helps to keep roots cool, deter weeds, and also prevents moisture loss. Avoid using high nitrogen fertilizers, as they produce enormous leaves with little flavor. Give liquid organic fertilizers that are rich in phosphoric acid or potash content.

Species of Stevia

The family of Stevia has about 154 species; six species are generally used that are Stevia eupatoria, Stevia ovata, Stevia plummerae, Stevia salicifollia, Stevia serrata, and Stevia rebaundiana. From all these, Stevia rebaundiana is the one with noteworthy sweetening properties. The property of the species that pointed out the plant was the extraordinary sweet tests of the leaves and watery extracts.

Popular Varieties of Stevia with Their Yield

Below are some popular varieties of stevia which are grown in Indian Climate condition

SRB-128: This variety is suitable for both southern as well as north Indian climates. It has a very high total glucoside content of 14-15 %.    

SRB-512: This variety grows well in northern latitudes and it can be harvested 3 or 4 times in one year. Total glucoside content varies between 9-12 %.

Pests Control in Stevia

Most pests are not found in Stevia crops because steviol glycoside itself has a sizeable pest repellant quality, but some of the modern high yielding breeds of Stevia needs crop safety to some extent. However, if pest appears they can be controlled by spraying neem oil with diluted water on the crop.

Commonly, non-favorable conditions, the excessive moisture level in soil and air, weed infestation, and unbalanced nutrients becomes the reason for pests and diseases in stevia crop. At this moment, perfect nutrients and appropriate agronomic management can work as a shield.

Diseases of Stevia

Septoria stevia:

Grey spot appear on leaves followed by chlorosis is caused by the fungus Septoria steviae. The disease spreads most fastly during high rainfall with cool night temperatures.

There are basically three methods for controlling Sclerotinia sclerotiorum; chemical, cultural, and organic control. The chemical and cultural control technique is generally used to lessen infection. The main synthetic control that is utilized to control Sclerotinia sclerotiorum is fumigation.

Southern blight:

it is caused by soil-borne fungus Sclerotium rolfsii. Soil solarization is an effective way to kill Southern blight.

Harvesting and Storage

The first harvest of the crop can be done in four months after planting and ensuing harvest once every three months. Generally, after 40 to 60 days of harvest, you can go for the next one.

Green stevia should be harvested early in the morning when it has the highest sugar content. Cool temperatures and short days heighten the sweetness of stevia. From one plantation cycle, a farmer can produce three harvests. Each harvest cycle should be performed with a space of 3-4 months.

For drying the leaves, tie the stems in small bundles and hang them upside down in a cool, dark and well-ventilated room until the leaves dry. When green leaves turn dry, remove the leaves from the stems and store in airtight containers. Grind them into a powder before use.

Packaging
