 Climate & Soil
Coriander requires cool climate during growth stage and warm dry climate at maturity. It can be cultivated in all most all types of soils but well drained loamy soil suits well. It is observed that quality of seed is superior & essential oil content is more when the crop is grown in colder regions & at high altitudes. It is also grown in house gardens.
Land Conditions
Land should be ploughed 2-3 times followed by planking, to bring the soil to fine tilt. Clots should be broken and stubbles of previous crop should be removed. Before land preparation, pre-sowing irrigation should be given.
Irrigation
Generally, 4-6 irrigations are given depending on type of soil and climate. First irrigation should be given within 30-35 days from the date of sowing, second after 50-60 days, third after 70-80 days, fourth after 90-100 days, fifth after 105-110 days and sixth after 115-125 days.
Weeding
During early stages of growth, coriander plants grow very slow, hence weeding during this period is very essential to save the plants from weed competition. In rain fed crop, first weeding should be done at about 25-30 days after sowing and in irrigated crop about 40-45 days after sowing. Thinning of plants should be done before first irrigation to maintain a spacing of 5 to 10 cm between plants. Second weeding should be done 50-60 days after sowing, in rainfed crop.
PEST
Aphid
Aphid infestation occurs at the time of flowing or after flowering in coriander crop. It sucks the sap from tender parts of the plants resulting in heavy loss. Spraying of 0.3% solution of Malathion or 0.1% solution of Dimethoate should be done to control this insect. Sowing during last week of October to first week of November can minimize the damage caused by aphid.
Cutworm
It is a caterpillar, brownish in colour, which cuts the plants from ground level and make them to fall down. Infestation of this pest starts at the initial stage of plants resulting in heavy loss to the crop. Dusting of 4% Endosulphan dust @ 20 -25 Kg/ha should be done while ploughing to prevent the crop from infestation. Drenching of Chlorpyriphos before last ploughing is also recommended.
DISEASES
Powdery Mildew
Attack of this disease is seen during cloudy weather condition. White powdery growth appears on the leaves and buds during its primary stage. Seed formation may not take place in affected plants due to this disease. To control this disease, dusting of Sulpher dust @ 20-25 Kg per hectare should be done. Spraying of wettable sulphur or Kerathane can also control this disease.
Wilt disease
Attack of this disease is seen during cloudy weather condition. White powdery growth appears on the leaves and buds during its primary stage. Seed formation may not take place in affected plants due to this disease. To control this disease, dusting of Sulpher dust should be done. Spraying of wettable sulphur or Kerathane can also control this disease.
STEM GALL
Galls appear on the leaves and stems of the plants affected by this disease. Shape of coriander seeds change due to effect of the disease. Increasing level of humidity, intensifies the effect of this disease on crop. To control the disease, sowing may be done only after treating the seeds with 1.5 g Thiram and 1.5 g Bavistin . Spray 0.1% solution of Bavistin when the symptoms start appearing and repeat the spraying at an interval of 20 days till the disease is completely controlled.
Blight
In this disease dark brown spots appears on the stem and leaves of infected plants. Spraying of 0.2% solution of Mancozeb should be used to control this disease.
