Agro-Climatic conditions for Coriander Cultivation:- Coriander grows well in dry and cool weather. It does not tolerate any frost. Coriander performs well at a temperature range of 20 to 30 °C.
Best season to grow Coriander:- June to July & October to November.
Soil requirement in Coriander Cultivation:- Coriander grows well in well drained loamy soils. The Optimum PH range 6 to 8 in soil is best suited for its cultivation.
Seed Rate in Coriander Cultivation:- Whole Coriander seeds will not germinate and hence the seeds are split open into halves before sowing. Seed rate is about 20 to 25 kg/ha in rainfed crop condition, and 10 to 12 kg/ha in irrigated crop condition.
Seed Treatment in Coriander Cultivation:– Soak the seeds in water for 12 hours for better germination. Treat the coriander seeds with Azospirillum @ 1.5 kg /ha for better crop establishment and to control wilt disease, Trichoderma viride @ 50 kg/ha.
Pre sowing seed hardening treatment with Potassium Dihydrogen Phosphate @ 10 grams/liter water for 16 hours should be done for rainfed crop condition.
Field preparation and sowing in Coriander Cultivation:-
- Start preparing the main field to a fine tilth. (3 to 4 ploughings may be required).
- Add Farm Yard Manure (FMY) to the soil @ 10 tones/ha before last ploughing.
- Should form channels and beds for irrigated crop.
- Should sow the split coriander seeds @ a spacing of 20 cm x 15 cm.
- Should spray pre-emergence herbicide called Fluchloralin 700 ml by mixing with 500 liter of water per ha.
- The seeds start germinating in about 1 week – 2 weeks.
Manuring in Coriander Cultivation:- Top dressing should be done at 10 kg N/ha 1 month after sowing for the irrigated crop only. Should consider to add Farm Yard Manure (FMY) 10 tons/ha; 40 kg P,10 kg N and 20 kg K for rainfed and irrigated crops.
Irrigation in Coriander Cultivation:- 1st irrigation should be given immediately after sowing and the second on the third day and subsequent irrigations at 6 to 10 days interval. In rainy season, crop hardly requires any irrigation.
Cultivation care in Coriander Cultivation:- Should apply pre-emergence spray of herbicide Fluchloralin 700 ml in 500 liter of water/ha. Thinning should be carried out after 1 month of sowing.

Pests and Disease in Coriander Cultivation:- Following are the Pests and Diseases found in Coriander cultivation.
Powdery mildew: Seed should be treated with Pseudomonas fluorescens (Pf 1) @ 10 grams /kg and foliar spray of Pf1 2 grams/liter or Dinocap 250 ml/ha or spray Wettable sulphur 1 kg/ha at the time of initial showing of the disease and second spray @ 10 days interval. Should spray Neem seed kernel extracts 5 % thrice (1st spray immediately after the showing of disease, second and third at 10 days interval).
Wilt: To contriol this, seed should be treated with Pseudomonas fluorescens @10grams/kg followed by soil application of Pf1 @ 5 kg /ha.
Grain mould: Grain mould can be controlled by spraying Carbendazim 0.1% , which is 500 grams /ha 3 weeks after coriander grain set.
Harvesting of Coriander:- The coriander plants are pulled just when the fruits are in fully ripe stage but green and start drying. The plants should be dried and thrashed with small sticks. Seeds should be cleaned. For fresh coriander leaf, pull out the plants when they are 30 to 35 days old.
