4. Stevia
 Stevia is a perennial herb
 Stevia is known all over the world due to its sweet
leaves and zero caloric.
 Stevia leaves contain sweetening compounds.

6. Economic Importance:
 Two cuttings can be gain from stevia in a year.
 Its per acre profit is many times greater than
other one year crop layout like
 wheat+cotton
wheat+rice.

7. Medicinal Importance
 Regulates blood pressure
 Control blood sugar and Insulin levels
 Due to zero calories it is control diabetes
 Weight loss
 Anti-fungal, anti-viral, anti-inflammatory etc.
 Prevents cancer
 Lowers cholesterol level
 Useful for skin care
 Prevents osteoporosis
 Strong blood vessels
 It’s extract is useful for dandruff.

8. Time and Method of Cultivation:
 We prepare nursery for stevia cultivation.
 Nursery can be prepare from seed, propagules and
tissue culture.
 Seed nursery can be transplanted after 2 months .
 Propagules and tissue culture nursery can be
transplanted to field after 1 month.
 For spring cultivation, nursery grow in November and
transplanted to field in February.

9. Land Preparation:
 Loamy soils are more suitable for stevia
cultivation.
 The land should be ploughed initially 2-3
times with harrowed or disc plough to break
the clods with 2 plankings to fine the soil.

10. Sowing Method:
 Crop is grown on raised beds because
intercultural operations are easily handled by
manual labor.
 Raised bed should be of 15cm in height.

11. Irrigation
 According to weather and soil conditions, 1-2
light irrigation’s should be done in a week.
Fertilizers:
 Use 2 bags of urea, 1 bag DAP and 1bag
potassium sulfate per acre for good production.

12. Weeds Management:
 Stevia requires hoeing and weeding.
 Manually removal of weeds are more
preferable because its leaves use directly or
indirectly for eating purpose.
 First weeding or hoeing done after 15 days
 subsequent hoeing and weeding will be done
one month after the first weeding and
hoeing.
 Hoeing is also required immediately after
harvesting

13. Insects and their Control
 Insects of stevia are termites, aphid, jassid,
thrips and army worm but these do not cause
serious or more damage.
 Control becomes necessary for insects which
cause more damage.
 Avoid the use of pesticides on stevia.

14. Diseases and their Control
 Root rot disease in stevia.
 plant starts becoming yellow from bottom to upper
site and completely dry.
 It’s attack is more at initial stages.
 Mix 400g Topsin-M in 100 liter water and spray
around the roots to control the root rot disease.

15. Pinching
 It is done by cutting the growing tips of stevia
plants every 2-3 weeks for the first month.
 This practice is done to encourage new and bushy
growth, produce dense foliage and promote healthy
growth.
 During pinching the buds and one pairs of leaves
are removed by clean and sharp cutters.
 It helps to prevent breakage of stems during high
winds.

16. Harvesting
 First harvesting after 4 months and subsequent
after every 3 months
 Harvest the leaves before flowering because
sweetness is more in leaves before flowering.

17. Method of Dry:
 Immediately after harvest the herb is dried.
 Put the leaves in shade for dry after thoroughly
wash.
 It can also be dried
 Using simple drying racks inside transparent poly
house
 By passing dry air just above room temperature.

18.  Yield
 From 2 cuttings 40-45 mounds of dry leaves per
acre can be obtained.
 Packaging
 Dry leaves are stored in plastic lined cardboard
boxes, sealed and strapped.
 labeled for further processing.

19. Types of Stevia Products
 Types of stevia products
 Fresh stevia leaves
 Dried stevia leaves
 Stevia extracts
 Liquid concentrates
