Apply 10 kg of FYM, 100 g of NPK 6:12:12 g mixture as basal dose/pit and N @ 10 g/pit at 30 days after sowing.Apply Azospirillum and Phosphobacteria @2 kg/ha and Pseudomonas 2.5 kg/ha along with FYM 50 kg and neem cake @ 100 kg before last ploughing.

Drip irrigation
Install drip system with main and sub-main pipes and place the inline lateral tubes at an interval of 1.5 m. Place the drippers in lateral tubes at an interval of 60 cm and 50 cm spacing with 4 LPH and 3.5 LPH capacities respectively.

Sowing
Dig pits of size 45 x 45 x 45 cm at spacing of 2 m in row spaced at 1.5 m. Sow three seeds in each pit. After germination, thin to 2 healthy seedlings. Instead of direct sowing, the seeds can be sown in poly bags @ 2 seeds / bag and 15 days after germination, they can be planted @ 2 seedlings per pit.

Fertigation
Apply a dose of 250:100:100 kg NPK/ha throughout the cropping period through split application.
