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

For vegetable purpose, optimum time for sowing is first week of October and when grown for seed purpose, complete sowing in last week of October to first week of November.

Spacing

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

Sowing Depth

Depth of soil should not exeed 3cm.

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 2parts. Before sowing, soaked seeds in water for 8-12hr. To prevent crop from wilt disease,root rot and damping off, treat seeds with Trichoderma viride/Pseudomonas fluorescens @ 4gm/kg of the seeds at before sowing."

Fertilizer Requirement (kg/acre)

Nutrient Requirement (kg/acre)

For good growth of crop, apply Nitrogen@25kg in form of Urea@55kg/acre and Phosphorus@20kg/acre in form of SSP@125kg/acre. Apply half of Nitrogen and full dose of Phosphorus at time of sowing. Apply remaining amount of Nitrogen at time of flower initiation.

To attain fast growth 15-20days after germination take spray of Triacontanol hormone@20ml/10Ltr. Also one spray of NPK(19:19:19) fertilizer@75gm/15Ltr of water at 20days of sowing helps in good and faster growth of crop. To obtained more yield, spray Brassinolide@50ml/acre/150Ltr water, 40-50 days after sowing. Take its second spray after 10days. Also one spray of Mono ammonium Phosphate 12:61:00@45gm/15Ltr of water at leaf and branches growing stage helps in good growth and increases yield.

Depending upon soil texture, rain and climate, four to five irrigation are required for good growth of crop. Apply first irrigation 30days after sowing. Apply remaining irrigation on 60-70th day, 80-90th, 100-105th and 110-150days. Avoid moisture stress at flowering and seed development stage. 

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. 

• Pests 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.

• Diseases 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.
