The dry leaf yields greatly differ depending on a number of factors. They
primarily include:
- Germplasm characteristics
- Soil nutrition level
- Irrigation
- Age of plantation
- Spacing
- Growing conditions
- Management Practices
|
Maximum yields are recieved in the second and the third year in
comparison to the first year. Seed yields mature when plants are 4 to 5
years of age. The productivity of these plants can continue upto 20 years
but a decline in the yeild becomes notable by 12 years. If the leaf and seed
yields are good, then their production ranges from 500 kgs to 2,500 kg a
year.
