INTRODUCTION

ABOUT STEVIA


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.

IMPORTANT OF PLASTIC MULCH IN STEVIA CULTIVATION.


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.

Limitations:

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

mulches.

• 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 .

Conclusion:

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.
