how to grow Coriander(dania)

Corriander (Coriandrum sativum L.) is an annual herb that belongs to the carrot family. The bright green
plant is erect and glabrous (hairless), reaching heights of 16 to 24 in. (40 - 60 cm). The compound lower
leaves are roundish and lobed, while the upper leaves are finely divided into very narrow, lacy segments.
The small white or pink flowers are borne in compound umbels that measure approximately 1.6 in.
Adaptation
· Well-drained loam and sandy-loam soils
· Suitable soil pH ranges are from 4.5 to 8.0, with an optimum of 6.3
· Optimum growing temperature of 18° C.
Site Selection and Soil Preparation
Choose a site that is flat and preferably near a reliable water source. Site should be where crops,
especially carrots, have not been grown before, free from wildlife and human interference.
Land Preparation
1. Solarize (optional) the area soil for at least one month
2. Spray soil on selected area with pre-emergence herbicide (Touch down)
3. Thoroughly plough the site 15 centimeters deep or more
4. Remove all debris and any volunteer growth
5. Prepare a fine tilth mixture of well-cured manure/Urea and the soil
6. Raise beds; conventional 1 meter by 5 to 10 meters
7. Spray the beds with fungicide and other pestcide to avoid fungal diseases and repel pests
respectively

Sowing
1. Before sowing, the soil should be thoroughly watered
2. Treat seed with fungicide is in swampy areas to avoid fungal diseases
3. Seeds are drilled on the rows opened at 10cm space and 2-4 cm depth
4. Cover seeds with a thin layer of soil
5. Irrigate with a light water shower
6. Cover with mulch (dry grass) at 3-5cm thickness
Bed maintenance
· Irrigate with watering-can in the morning or afternoon from sowing until two seedlings emerge
· Once seedlings start germinating, remove mulch and continue irrigating twice a day
· Apply registered fungicides and pesticides within 3-4 days after grass cover removal; insecticides
application depends on disease or insect appearance
· Perform gentle hand weeding post-emergence
Disease Control
· Control fungal diseases like Seedling rot and Damping-off using registered fungicide- avoid chemical
pesticides from the onset of the third week (heavy foliar stage)
· Crop rotations out of the carrot family for several years can help reduce disease problems
· Using clean seed can help prevent the introduction of disease into new fields or areas
