Seed Treatment: Azospirillum @ 1.5 kg /ha
Field preparation and sowing: Prepare the main field to a fine tilth and form beds and channels (for irrigated crop). Sow the split seeds at a spacing of 20 x 15 cm. The seeds will germinate in about 8-15 days.
Presowing seed hardening treatment with Potassium Dihydrogen Phosphate @ 10g/lit of water for 16 hours is to be done for rainfed crop.
Seeds are to be treated with Azospirillum @ 3 packets/ha.
Seed treatment with Trichoderma viride @ 4 g/kg of seed has to be done to control wilt disease.

Seed rate: 10 - 12 kg/ha.
Broadcast the seeds for rainfed crop. (20 – 25 kg/ha)

Clipping coriander : 60 kg N : 40 kg P : 60 kg K kg / ha.
Split : 35th day 30 kg N
55th day 30 kg N after clipping.
Basal: FYM 10 t/ha; 10 kg N, 40 kg P and 20 kg K for rainfed and irrigated crops.
Top dressing: Top dressing may be done at 10 kg N/ha 30 days after sowing for the irrigated crop only.

Irrigation (for irrigated crop only): First irrigation immediately after sowing and the second on the third day. Subsequent irrigations at 7-10 days interval.

Aftercultivation: Pre-emergence spray of herbicide Fluchloralin 700 ml in 500 lit/ha. Thinning is done 30 days after sowing. Subsequent weeding is done as and when necessary. Leave 2 plants per hill. Spray CCC @ 250 ppm one month after sowing for inducing drought tolerance in
rainfed crops.

Plant protection
Aphid: Spray methyl demeton 25 EC @ 2 ml/lit or dimethoate 30 EC @ 2 ml/lit.

Powdery mildew: Spray Wettable sulphur 1 kg/ha or Dinocap 250 ml/ha at the time of initial appearance of the disease. Neem seed kernel extract 5% spray thrice. (1st spray immediately after the appearance of disease. 2nd and 3rd at 10 days interval. 3 sprays of NSKE (5%), 1st spray immediately after appearance of the disease, 2nd & 3rd at 15 days interval.
Grain mould: Spray Carbendazim 0.1 % (500 g/ha) 20 days after grain set.
Harvest: The plants are pulled just when the fruits are fully ripe but green and start drying. The plants are dried and thrashed with sticks, winnowed and cleaned. For leaf, pull out the plants when they are 30-40 days old.

Rainfed Grain yield : 300-400 kg/ha.
Irrigated : 500-600 kg/ha
Leaf yield : 6-7 t/ha.
