Varieties : 2.5 kg/ha.
Hybrids : 1.50 kg /ha
Hydropriming for 24 h with seed to water ratio of 1:4.
Treat the seeds with Trichoderma viride @ 4g/kg or Pseudomonas fluorescens @10g/kg before sowing.
A deep loamy soil with pH range of 6.5-7.5 is suitable
For varieties, apply FYM @ 10 kg/ pit along with 100 g of NPK mixture (6:12:12) per pit as basal and 10 g N/pit as top dress on 30 days after sowing.
Hybrids Apply NPK @ 200:100:100 kg per hectare.
Basal Dose : 50% of N&K and full of P
Top dressing : 50% of N & K, 30 DAS
Irrigate the basins before dibbling the seeds and thereafter once a week.
Varieties : 30 – 35 t/ha
Hybrids : 80-90 t/ha
Matured fruits can be stored over sand bed at ambient condition.
Nursery raising
In hi-tech horticulture, use 12 days old healthy seedlings obtained from shade net
houses for planting. Raise the seedlings in protrays having 98 cells. Use well decomposed
cocopeat as medium. Sow one seed per cell. Water regularly twice a day. Transplant about
12 days old seedlings in the main field
