Agro technology/Cultivation practices |
Prefers a rich light sandy soil, but thrives best in a fertile calcareous soil. This plant shows better growth from neutral to alkaline pH.
Cultivation
1. Planting stock production: seeds are used as propagating material. For
one hectare, 7-8 kg of seeds are required.
2. Field planting: After collecting the seeds from brown pods, scarify them
by carefully scraping with a knife. This will help the germination
process. Then soak the seeds in warm water for 24 hours. Seeds sowed in
vermiculate will germinate in 3-8 weeks. March is the best time for seed
sowing. Transplant the seedlings in the field when they attain 8-12 cm
height during May.
3. Manuring/Fertilizer: Apply farmyard manure/compost based on plant/soil
analysis.
4. Irrigation: Irrigation is necessary at the time of transplanting
seedlings in the field. Thereafter, irrigate in every 10-15 days
interval.
5. Pest and diseases: This species is extremely susceptible to the various
viruses that affect the potato family (Solanaceae), it can act as a
center of infection, so should not be grown near potatoes or tomatoes. |
Harversting |
Plants usually start flowering after 4 months from sowing the seeds, and is the stage for harvesting. Subsequent harvests can be done in every 1-2 months interval. Fruits are harvested when they ripe and turn into brown colour. |
