Coriander is a fast-growing, aromatic herb that grows in the cooler weather of spring and fall.This herb is used to flavour many recipes, and the entire plant is edible.The leaves are called cilantro, and the seeds are called coriander.
Scientific name-Coriandrum sativum.
Climate and soil requirement for growing Coriander
It requires cool climate in early stages and warm, dry weather at maturity. It can be sown on a wide variety of soil, but it performs best in well-drained sandy loam to loamy soils.
Improved Coriander variety
Punjab Sugandh (2008)
Its green plants are semi-erect and produce profuse tillers. Leaves are medium in size, green, tender and excellent in the aroma. It is late in bolting and give four cuttings of green leaves. The average green leaves yield is 150 q, and of seed is 3.5 q/acre.
Agronomic Practices for Coriander cultivation
Prepare a fine seedbed by giving two or three ploughings, each followed by planking.
Use healthy and dis for free capsules (seeds). Rub the capsules gently to break them into 2 to 4 parts. Unrubbed capsules give very poor germination. Treat the seed with Thiram @ 2.5 g per kg of seed.
Time and Method of Sowing
Optimum period of sowing for green leaves is the first week of October and for seed last week of October to the first week of November. However, it can be continued up to last week of December. Sow by pora method in rows 30 cm apart.
The slow growth of coriander in the initial stages poses a serious weed problem. Give two weedings, preferably with improved wheel hand hoe, the first about four weeks after sowing and the second 5-6 weeks after that.
Irrigation of Coriander
Give four or five irrigations depending upon the soil and rainfall. The first irrigation may be given about three weeks after sowing. Subsequent irrigations may be given as and when required taking care that there is no moisture stress, particularly at flowering and seed development stages.
Manures and Fertilizers for Coriander
Apply 40 kg N (90 kg Urea) in three split dozes, one-third at sowing and remaining in two equal splits after first and second cutting of green leaves. However, for seed crop apply 30 kg N (65 kg urea) per acre in two splits, half at sowing and the remaining half at flower initiation. There is no need of applying phosphorus to soils testing medium to high in this nutrient.
Harvesting and Threshing of Coriander
The green leaves are harvested on attaining 20-25 cm height. Therefore, 3-4 cuttings can be taken from green leaves. The crop is ready for harvest by the end of April. Harvest when the capsules are mature but green. The green colored fetch a price premium over the brown colored over-ripe capsules. Remove the harvested produce to a pucca threshing floor, allow it to dry and then thresh. Dry the capsules fully before storage.
A) Insects of Coriander
No serious insect pests appear.
B) Diseases of Coriander
The disease forms tumor-like swelling on leaf veins, petioles, peduncles, stems, and capsules. The fruits in the umbels may become enlarged. Remove and burn the diseased plants.
Treat the seed as given under seed preparation.
