i. Seed rate and treatment

10 kg of seeds is required to sow one hectare and the seeds are split into two before sowing.

The seeds are treated with Azospirillum @ 1.5 kg/ha and shade dry for an hour

Seed treatment with Trichoderma viride @ 4 g / kg of seed is done to control wilt disease.

ii. Field preparation and sowing

The main field is ploughed 4 times with Chisel and disc plough each one time and cultivator twice.

FYM @ 25 t /ha is applied before the last ploughing.

75% of the total recommended dose of super phosphate i.e. 200 kg/ha is applied as basal dose.

Azospjrillum and Phosphobacteria each @ 2 kg/ ha along with FYM 50 kg and Neem cake @ 100 kg is applied before last ploughing.

Raised beds of 120 cm width and 30 cm height are formed through broad bed former.

Raised beds of 120 cm width (4 feet) are formed at an interval of 30 cm (1 feet)and the laterals are placed at the center of each bed.

Sowing is done in lines of 15 cm spacing in the raised beds. Hence 8 lines are formed in one single bed.

The beds are wetted after sowing, through drip irrigation system for 8-12 hours depending upon the soil moisture level.

The seeds are germinated 8-12 days after sowing.

Immediately after the observation of gaps, gap filling is done to maintain the population.

iii. Fertigation

A dose of 60:40:60 kg of NPK/ha is applied through fertigation.

75% of the Phosphorous is applied as basal dose during last ploughing.

Fertigation is done in once in three days.

iv. Intercultivation

Weeding is done once on 20th day after sowing.

Thinning is done on 30 days after sowing.

v. Harvesting
