Prepared land by giving two or three ploughing and do planking after ploughing operation to make uniform and levelled bed. Before last ploughing add, 40qtl/acre of well decomposed cow dung in soil.

Time of sowing
The optimum time for seed sowing is mid-October to mid-November.

Spacing
Keep row to row distance of 30 cm and plant to plant spacing of 15 cm.

Sowing Depth
Depth of soil should not more than 3 cm.

Method of sowing
Use Pora method for sowing.
 

Seed Rate
For sowing one acre land, seed rate of 8-10kg is used. 

Seed treatment
For quick germination, before sowing crushed, break seeds into 2 parts. Before sowing, seeds are soaked in water for 8-12 hours. To prevent crop from wilt disease, root rot and damping off, treat seeds with Trichoderma viride/Pseudomonas fluorescence @ 4gm/kg of the seeds at before sowing.

Fertilizer Requirement (kg/acre)

Nutrient Requirement (kg/acre)

At the time of ploughing, mix the Cow dung@4tonnes/acre in the soil. Application of nutrient dose such as Urea@25kg/acre, DAP@25kg/acre and MoP@12kg/acre should be done. Half dose of nitrogen should be added at the time of sowing and rest of the half dose is added after 30-35 days. In irrigated areas, use Urea@25kg/acre and the nitrogen is given in three equal splits; one at the time of sowing, second after 25-30 days and third after 45-50 days. Spraying of zinc@5ppm after 50-60 days of sowing will help to increase the yield upto 20-25%.

At initial growth stage of coriander, weed is a serious problem. Take one or two weeding operations to keep field weed free. Take first weeding 4week after sowing and second 5-6week after sowing.

Irrigation should be given according to soil moisture present in the soil. First irrigation should be given immediately after sowing of seeds. Subsequent irrigations should be given at 10 to 12days interval.

• Pest and their control:
  

Aphid: If Infestation of Aphid is observed, to control take spray of Imidacloprid@6ml/10Ltr water or Thiamethoxam@4gm/10Ltr of water.

• Pest and their control:
  

Powdery Mildew: Patchy, White powdery growth appears on upper surface of leaves.

If infestation is observed take Spray of water soluble Sulphur@20gm/10Ltr of water. If needed repeat spray with interval of 10days or take spray of Propiconazole10EC (Topas)@200ml/acre in 200Ltr of water.

Grain Mould: To prevent crop from grain mould, take spray of Carbendazim@200gm/acre 20 days after grain set.

Root rot: To protect crop from root rot, as preventive measure do soil application of Neem Cake@60gm/acre. Also treat seeds with Trichoderma viride@4gm/kg of seed.

If infestation of root rot, observed in field to control, drenched soil with Carbendazim @5gm/Ltr of water or Copper oxychloride@2gm/litre of water.

When crop attained 20-25 cm height harvesting for green leaves can be started. Three to four cutting can be taken. When crop is grown for seed purpose, it is ready for harvesting in April month. Harvest when capsule gets matures but having green color. Over ripe capsule fetch lower price.

After harvesting allowed crop to dry in sunlight for 6-7 days. After proper drying, carry out threshing after then cleaning operation.
