Stevia (STEVIA REBAUDIANA) leaves have functional and sensory properties superior to those of many other high potency sweeteners. Stevia is likely to become a major source of high potency sweetener for the growing natural food market in the future. Although Stevia can be helpful to anyone, there are certain groups who are more likely to benefit from its remarkable sweetening potential. These include diabetics, those interested in decreasing caloric intake, and children.

Origin of Stevia Rebaudiana is in central Paraguay where it grows near the ponds and streams in wild conditions. Native Paraguayans have been consuming this herb in large quantities for many centuries. It was only during early fifties that Japanese stumbled upon this unique herb and took it to Japan where they have developed many varieties of this wonderful herb for large scale cultivation The leaves of this plant are 30 times sweeter than sugar , with zero calories. Where as pure extract is 300 times sweeter than sugar.

Stevia Rebaudiana is a small perennial growing up to 65-80 cm tall, with sessile, oppositely arranged leaves. Different species of Stevia contain several potential sweetening compounds, with Stevia Rebaudiana being the sweetest of all. Stevia is a semi-humid subtropical plant that can be grown easily like any other vegetable crop even in the kitchen garden. The soil should be in the pH range of 6.5- 7.5; well-drained red soil and sandy loam soil. Saline soils should be avoided to cultivate this plant.

Stevia: the best trend for 2015

The food and health industry is rapidly changing, and many analysts are making their predictions for the trends that will dominate the food industry in 2015.

Whilst these predictions vary dramatically across the board, one trend that crops up time and time again is the health drive towards reducing calorie intake, especially from sugar. This health drive seems set to continue for a long time, as maintaining a healthy diet and lifestyle remains high on the public health agenda.

Despite a desire to reduce calorie intake, there is still a demand for sweetened food and drink products, suggesting an increased role for zero-calorie sweeteners in 2015 as further manufacturers are expected to adopt plant-based sweeteners into their products.

In 2012 the Truvia business kick started the trend in the UK by launching the first ever stevia based sweetener, a new category of sweetener offering calorie-free sweetness from a leaf. The introduction of stevia to the market was a significant breakthrough at a time of growing health concerns over obesity and diabetes. It was seen as the perfect answer to consumers’ desire for sweet tasting foods and beverages without the calories, and is derived from a natural plant source, which many consumers prefer to artificial alternatives. Since its introduction to the UK market three years ago, stevia is now worth over £4m and is growing at a rate of 18% year on year; it is the only area of sweeteners showing growth. 

While the value of stevia as an additive for use in food and beverage manufacture totalled $110 million in 2013, Mintel and Leatherhead Food Research forecasts this to grow to $275 million by 2017. They comment: “Post EU regulations, improved tastes and textures and increased consumer buy in and demand, stevia has been quietly gaining traction with consumers – and alongside that, usurping the traditional pecking order of more established sweeteners.” Healthcare professionals and consumers alike are acknowledging the benefits of stevia and appreciate its natural plant origin.

This is increasingly important as obesity continues to rise and cause significant health problems for many adults and children across Europe. Simple tweaks to the diet can make a significant difference. For example, zero and low-calorie sweeteners can play a useful role as part of a healthy, balanced diet as they can help patients to control their calorie intake. Research has shown that overweight patients consuming sweet foods are more likely to stick to their diets with the use of zero and low-calorie sweeteners in the initial phase following weight loss,. In addition, research has shown that the consumption of zero-calorie sweeteners neither stimulates the appetite nor results in increased food intake,. Stevia also has the potential to help alleviate the global burden of diabetes as people with Type 2 diabetes may find zero and low-calorie sweeteners useful in helping to manage the calories and carbohydrates in their diet. People with diabetes can safely consume stevia-based products and they have no effect on the glycaemic index,. Over the past few months the UK has seen an expansion in the number of food manufacturers offering reduced calorie product ranges, sweetened with stevia. As calorie reduction remains high on the agenda, it’s likely that 2015 will see stevia continue to become more mainstream

Today let’s talk about Stevia’s current trend in the global market and its future prospects.

The below studies by different international market research companies talk about Stevia’s exponential growth.

The Nielsen based data shows that stevia is a rapidly growing industry and that stevia is developing into a broadly mainstream ingredient in foods and beverages.

Global market for stevia will reach 11,000 tons by 2014 requiring tripling (three times) of stevia leaf production at the farm level.

Indian Market:  An estimated 10 to 20 per cent people in India have diabetes; the market for low-calorie sweeteners is at least 25 per cent if one combines the obese and weight conscious consumers with diabetics.  At 50.8 million, India had one of the largest diabetic populations in FY10. With an improvement in health awareness, the diagnostic and usage rates are likely to increase, leading to a rise in the number of diabetics consuming artificial sweeteners from 2.96 million FY10 to 9.6mn in FY15.

India scenario


Stevia is been successfully cultivated in the recent years at many areas of Rajasthan, Maharashtra, Kerala, Tamil Nadu and Orissa. The increasing demands for natural sweeteners have driven the farmers in India for Stevia cultivation in large scale.
One Hectare of Stevia Rebaudiana cultivation would be sweetener equivalent to 36 Hectares of Sugar Cane More so the sweetness in Stevia Rebaudiana leaves is healthy and harmless. .

Diterpene Glycoside is the group of natural sweeteners that have been extracted from Stevia. The leaves of wild Stevia plants contain
Dulcoside- 0.3 %
Rebaudioside C – 0.6 %
Rebaudioside A – 3.8 %
Stevioside – 9.1 %

Dried leaves have the following specifications:
Moisture Content: 5%
Glycoside: 3%
Stevioside: 12%

The plant is native to tropical and subtropical regions of North America and South America. There are near about 240 species of Stevia Genus There are about 90 varieties of Stevia Rebaudiana developed all around world. Basically all these varieties have been developed for different climatic requirements. Many times these varieties perform strangely in different climatic conditions. At the end of the day just like sugar cane it is the Steviocide and Rebaudiocide content in the Stevia leaves that determines the price and marketability of Stevia leaves.
 In many cases in south India it was observed that steviocide content was as low as 3.5 % which was below the minimum market requirement of  9% . Hence it becomes imperative that the grower select proper varieties with adequate guarantees from the planting material suppliers about minimum assured Steviocide and Rebaudiocide contents

This form of Stevia is the herb in its most natural, unrefined state. A leaf picked from a Stevia plant and chewed will impart an extremely sweet taste sensation reminiscent of licorice that lasts for quite a while. For Stevia to have a more practical application as a tea or sweetener, the leaves must be dried or put through an extraction process, which makes the sweet taste even more potent.

For more of the flavor and sweet constituents of the stevia leaf to be released, drying and crushing is necessary. A dried leaf is considerably sweeter than a fresh one, and is the form of stevia used in brewing herbal tea. Dried stevia leaf may come in bulk or packaged like tea bags. You can also get it finely powdered. It has a greenish color and can be used in a wide variety of foods and beverages, including coffee, applesauce and hot cereals. You also can use it to make an herbal tea blend. Its distinctive flavor is reminiscent of licorice, which will blend very well with different aromatic spices, such as cinnamon and ginger


The form in which stevia is primarily used as a sweetener in Japan is that ofa white powdered extract. In this form it is approximately 200 to 300 times sweeter than sugar (by weight).This white powder is an extract of the sweet glycosides (natural sweetening agents) in the stevia leaf.Not all stevia extract powders are the same. The taste, sweetness and cost of the various white stevia powders will likely depend on their degree of refinement and the quality of the stevia plant used. You may find that some powders have more of an aftertaste.Since extracted stevia powder is so intensely sweet, we recommend that it be used by the pinch (or drop if diluted in water). Once mixed, this solution should be stored in the refrigerator

Liquid Concentrates

These come in several forms. There's a syrupy black liquid (that results from boiling the leaves in water), which can enhance the flavor of many foods. Another type is made by steeping stevia leaves in distilled water or a mix of water and grain alcohol. You can also find a liquid made from the white powder concentrate mixed with water, and preserved with grapefruit seed extract

Stevia is a semi-humid, subtropical plant and can grow in the temperature ranges between 04 - 48 C. An annual average temperature of 31o C with a rainfall of 140 cm per year has been found optimum for its good growth. It shows good seed germination when subjected to light and warm conditions. Hence, a long growing season, minimal frost, high light intensities and warm temperature favors higher leaf production. Stevia is a short day plant, but the concentration of stevioside in the leaves increases when the plants are grown under long day conditions. The day temperatures should not exceed 48 oC and the night temperatures should not fall below 04 o C.

Soil & Propagation

Stevia grows well in sandy loam soils with an ample supply of water. stevia prefers acidic to neutral soil with a PH range of 6.5-7.5 for its best growth. Saline soils should be avoided as stevia plant is susceptible to water logged conditions.


Stevia plants can be propagated from cuttings or seeds or by tissue culture. As the seed germination is very poor and seedlings are very slow to establish, it is generally propagated clonally through cuttings. For vegetative propagation, stem cuttings of 15 cm length taken from leaf axils of the current year’s growth have been given better results. Treatment with Paclobutrazol @ 100ppm has been found to induce the root initiation in short time and IBA@500 ppm is also found to be effective. The best months for propagation are February-March. The cuttings will be ready for transplanting after 25-30 days of rooting.

During May or June month land should be deep ploughed  and get freely open so that  harmful soil born insects and other  undesired  substances will be destroyed.

As per requirement 10* 3*1 ½  ft  bed should be prepared.  Properly mix  50 Kg/bed organic compost .
In the mean time waste things should be cleaned from bed. After that according to rows seeds are put on the beds . After that seeds are covered  by  ½ cm thick layer of brawn  of rice and wheat. now prepared beds are ready to produce stevia plant.

Precautions :

Bed should be prepared under shadow area.
The  bed preparation area should be well drained .
Bed soil should be insect free.
Use appropriate insecticide , bactericide, fungicide  to protect stevia from insect or dieses.
Bird net should be used to protect bed from the birds.


Maintain moisture according to weather  on the stevia bed .
Be careful  ample supply of water invite insect dieses. So irrigate once in a day in winter and 3 or 4 times in a day in summer.
Bed height  should be 1 to 1 ½  feet above  from  surrounding land.
Keep 2 to 3 feet distance between 2 beds so that intercultural practices should be one properly.

After  5-6 days stevia plants get started grow.
Conteneous irrigation should be done as per requirement.
After 5 to 6 week stevia plants are ready for transplantation. Carefully take out plants and put them on  cold and well moisture place.
As much as possible transplant the plants on main land.

Management of Stevia cultivation is yet to mature in many regions and cultivators are
still on a learning curve. While tolerant of most soil types, Stevia is normally grown on
a sandy loam or loam. Stevia occurs naturally on soils of pH 4 to 5, but thrives with soil
pH as high as 7.5. However, Stevia does not tolerate saline soils. Normally there is no
pest or disease incidence reported in this crop. Harvesting starts after 3rd-4th month of

In India, Stevia cultivation is also looked upon as an opportunity to revitalise rural economies and tax incentives are being offered to take up cultivation. Bioved Research and Communication Centre (BRCC), UP, a centre which coordinates Stevia cultivation in the Northern State of Uttar Pradesh has reported that Indian climatic conditions suits Stevia cultivation due to ideal temperature conditions and the humidity ranging from 65-85 %. Scientific cultivation and careful selection of planting material can yield better returns in shorter times as compared to traditional crops according to Indian Stevia cultivators.Cultivation of stevia opens up new vistas for crop diversification and a viable
alternative to sugar cane in view of escalating cost of production due to extensive usage of chemical fertilizers, pesticides and irrigation requirements of sugarcane. Cultivation of stevia may be useful in the protection of environment, restoration of the health of soil, and revitalize the rural economy.

Since the 70’s, Stevia has been used in Japan as the main alternative to sugar instead
of the banned aspartame in diet soda, gum and other food and beverages. Stevia is
also used as a sweetener in other countries after extensive studies proved its safety.
Stevia has been used with success to treat many ailments including diabetes, high blood pressure, gingivitis, digestion ailments, and addictions, topically for acne and other skin ailments and also as a wonderful weight loss aid. Stevia provides several advantages over sugar and artificial sweeteners when used in food production, lower costs for transportation, storage/warehousing and handling charges:
In 2006, the World Health Organization evaluated Stevia and found no evidence of carcinogenicty in Stevioside and Rebaudioside A. It also reported that Stevioside
led to beneficial effects in patients with hypertension or with type-2 diabetes. The report concluded that further study was needed to determine proper dosage.

Mulching is a Agricultural practices to cover the soil with plastic or straw/wheat dust on the top of the
soil therefore, to control weed, excessive water evaporation & conserve soil moisture. Both organic &
in organic mulching have great benefit for stevia crop productivity.

Advantages of plastic mulching 

1. It is completely impermeable to water.

2. It prevents the direct evaporation of moisture from the soil and thus limits the water losses and conserves moisture.

3. By evaporation suppression, it prevents the rise of water containing salts.

4. Mulch can facilitate fertilizer placement and reduce the loss of plant nutrient through leaching.

5. Mulches can also provide a barrier to soil pathogens

6. Opaque mulches prevent germination of annual weeds from receiving light

7. Reflective mulches will repel certain insects

8. Mulches maintain a warm temperature even during nighttime which enables seeds to germinate quickly and for young plants to rapidly establish a strong root growth system.

9.Synthetic mulches play a major role in soil solarisation process.

10.Mulches develop a microclimatic underside of the sheet, which is higher in carbon-di-oxide due to the higher level of microbial activity.

11.Under mulch, the soil structure is maintained during cropping period

12. Early germination almost 2-3 days.

13. Better nodulation in crops like Groundnut.

14. Less nematodes population.

15.Water erosion is completely averted since soil is completely covered form bearing action of rain drops.

16.When compared to organic mulches, it serves for a longer period.

Moisture conservation.

To keep stevia leaves clean, market demand will increases.

• Plastic film with its moisture barrier properties does not allow the soil moisture to escape Water that evaporates from the soil surface under mulch film, condenses on the lower surface of the film and falls back as droplets.

• Thus moisture is preserved for several days and increases the period between two irrigations.

• The irrigation water or rainfall either moves into the soil thru holes on the mulch around the plant area or through the unmulched area.

Weed control:

• Black plastic film does not allow the sunlight to pass through on to the soil

• Photosynthesis does not take place in the absence of sunlight below black film hence, it arrests weed growth.


• They are costly to use in commercial production when compared to organic


• Probability of ‘burning’ or ‘scorching’ of the young pants due to high temperature of black film.

• Difficulty in application of top dressed fertilizer

•Reptile movement and rodent activities are experienced in some places.

• More runoff

• Environmental pollution

• Difficult in machinery movement

• Can not be used for more than one season using thin mulches

• Weed penetration with thin films

•Toxic to livestock.

Areas of application:

Mulching is mainly employed for

a. Moisture conservation in rainfed areas

b. Reduction of irrigation frequency and water saving in irrigated areas

c. Soil temperature moderation in greenhouse cultivation

d. Soil solorisation for control of soil borne diseases

e. Reduce the rain impact, prevent soil erosion and maintain soil structure

f. In places where high value crops only to be cultivated.

g. In the areas where high water scarcity like Rajasthan, Gujarat, Hariyana, Punjab in India, mulching will give better crop yield as compare to existing method.

Selection of mulch:

The selection of mulches depends upon the ecological situations and primary and secondary aspects of mulching

Rainy season ………………………………………..Perforated mulch.

Orchard and plantation…………………………………………….Thicker mulch

Soil solarisation …………………………………………………..Thin transparent film

Weed control through solarisation ……………………………….Transparent film

Weed control in cropped land………………………………………….Black film

Sandy soil ……………………………………………………………………Black film

Saline water use …………………………………………………………….Black film

Summer cropped land ………………………………………………………White film

Insect repellent …………………………………………………………….Silver colour film

Early germination ……………………………………………………… Thinner film .


Selection of mulch in stevia cultivation will depend according to Agro- climatic condition of a particular zone. We are realized the effect of plastic mulch in stevia cultivation in India. Famers/growers both are benefited for adopting this technique in their field. Production as well as cost of cultivation has been minimizing greatly. So, we advice our growers to adopt this technique to get better profit and control soil erosion as well as costing of cultivation.
