Cultivation Of Coriander

By Punjab Agricultural University on 29 Jan 2016 | read


Climate and Soil

It requires cool climate in early stages and warm dry weather at maturity. Coriander can be sown on a wide variety of soil but it performs best in well-drained sandy loam to loamy soils.

Improved variety

Punjab Sugandh (2008) : Its green plants are semi-erect, and produce profuse tillers. Leaves are medium in size, green, tender and excellent in 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

Preparatory Tillage : Prepare a fine seed bed by giving two or three ploughings, each followed by planking.

Seed Rate : Use 8-10 kg of seed per acre.

Seed Preparation : Use healthy and disease free capsules(seeds). Rub the capsules gently to break them into 2 to 4 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 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.

Weed Control : The slow growth of coriander in the initial stages poses a serious weed problem. Give two weeding, preferably with improved wheel hand hoe, the first about 4 weeks after sowing and the second 5-6 weeks thereafter.

Irrigation : Give four or five irrigation depending upon the soil and rainfall. The first irrigation may be given about 3 weeks after sowing. Subsequent irrigation 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

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

The green leaves are harvested on attaining 20-25 cm height.Therefore, 3-4 cuttings can be taken of 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.

Plant Protection

a) Insects

No serious insect-pests appear on this crop.

b) Diseases :

Stem gall : The disease forms tumor like swelling on leaf veins,petioles, peduncles, stems and capsules. The fruits in the umbelsmay become enlarged. Remove and burn the diseased plants.Treat the seed as given under seed preparation.
