Coriander is an easy-to-grow annual herb that is used in a variety of cuisines around the world. It is a versatile plant that can be grown in a variety of soils and climates, making it a popular choice for home gardeners. Coriander can be grown from seed or from transplants. The seeds should be planted in early spring, once the frost danger has passed. The plant should be kept moist but not wet. When the plants are 6–8 inches tall, thin to 12 inches apart. Coriander should be harvested when the leaves are still tender. For the best flavor, harvest in the morning when the essential oils are at their peak. Dried or fresh leaves can be used for later. The seeds should be harvested when the leaves turn brown and are dry. The seeds can be ground for a flavorful addition to dishes. With proper care, a single coriander plant can produce several harvests throughout the season.

The best season to grow coriander is during the cooler months of spring and autumn. Coriander thrives in cooler weather and higher humidity. Ideal conditions for growing coriander include temperatures between 60-70°F (15-21°C) with plenty of sunshine and adequate moisture. The soil should also be well-drained, fertile, and slightly acidic. Coriander does not tolerate extreme heat or cold, so it should not be planted outdoors until temperatures remain consistently above 60°F (15°C).
Coriander prefers well-drained, light and sandy loam soil that is rich in organic matter. It should be slightly acidic, with a pH of 6.0-7.0. The soil should be well aerated and drained and should not be waterlogged or heavy. Coriander prefers full sun exposure but can tolerate some light shade.
The most widely cultivated varieties of Coriander in India are:
1. Pusa Mausami
3. Pusa Ajeet
4. Pusa Sadabahar
5. Pusa Nimboo
6. Pusa Jaiphal
7. Pusa Suraj
8. Pusa Jyoti
Seed rate for coriander cultivation is 4-6 kg/ha. The seed rate depends on the soil type, seed variety and climatic conditions. It is important to use the right seed rate to get good yields. Higher seed rate can result in overcrowding of plants and lower seed rate can result in poor yields. The seed rate should also be adjusted according to the weed pressure and soil fertility. For better germination of seeds, it is important to use good quality seed, which is free of weed seeds and diseases.
Seed treatment is an important agronomic practice in coriander cultivation. It helps to protect seeds from soil-borne diseases, as well as to enhance their vigor. The treatment involves soaking the seeds in fungicides, insecticides, and other agrochemicals for a certain period of time before sowing. This helps to reduce the risk of disease and insect infestations, and increases the germination rate of the seeds. Seed treatment also helps to improve the vigor of the plants, resulting in higher yields. Additionally, it can also help in reducing the pre-harvest losses due to pest and disease infestations.
1. Soil Preparation: Coriander is grown in well-drained, sandy loam soils. To prepare the soil for coriander, the soil should be plowed several times to incorporate organic matter and to break up any soil clods.
2. Fertilizer Application: A balanced fertilizer such as 10-10-10 should be applied at the rate of 40 to 50 kg/ha. Compost or well-rotted manure should also be added in the soil at the rate of 10 to 15 tonnes/ha.
3. Sowing: Coriander seeds should be sown in the prepared field after the last frost when the soil temperature reaches a minimum of 18°C. The whole seed cannot be germinated hence the seeds should be split into halves before sowing.The seeds should be sown in rows at a spacing of 15 cm. The seeds should be sown 2 cm deep in the soil. It is recommended to water the sown area immediately after sowing.
4. Irrigation: The soil should be kept moist throughout the growing season. It is recommended to irrigate the crop regularly to ensure optimum growth and yield.
5. Weeding: Weeds should be controlled by frequent weeding or mulching. Hand weeding or hoeing should be done when the weeds are small.
6. Harvesting: Coriander is ready for harvesting when the leaves turn brown and the seeds turn black. The crop can be harvested by cutting the plants at the base. The harvested material should be dried in the sun and the seeds can be threshed and stored in airtight containers.
Coriander prefers light, well-drained, loamy soil with a pH of 6-7. It should be free from weeds, stones, and other debris.Coriander can be sown directly into the soil or started in seed trays and transplanted. Seeds should be planted 1 cm deep and spaced 5-7 cm apart.Coriander requires regular watering but the soil should not be waterlogged. Water the plants at the base to avoid wetting the leaves.Coriander benefits from a light application of nitrogen-rich fertilizer every 3-4 weeks.Weeds should be removed by hand to prevent them from competing with the plants for nutrients.
Powdery Mildew Aphids: Aphids are tiny, soft-bodied insects, usually green, black, or brown in color, that can be found on the underside of the leaves and stems of coriander plants. They feed on the sap of the plant, and can often be seen clustered together in large groups. They can cause damage to the plant by sucking out the sap, which can lead to wilting and yellowing of the leaves.
Whiteflies: Whiteflies are small, white flying insects that can be found on the underside of the leaves of coriander plants. They feed on the sap of the plant, and can cause yellowing and wilting of the leaves. They can also transmit viruses to the plant.
Thrips: Thrips are small, slender insects, usually black or brown in color, that can be found on the underside of the leaves and stems of coriander plants. They feed on the sap of the plant, and can cause yellowing and wilting of the leaves.
Leafhoppers: Leafhoppers are small, green or brown insects that can be found on the underside of the leaves of coriander plants. They feed on the sap of the plant, and can cause yellowing and wilting of the leaves. They can also transmit viruses to the plant.
Cutworms: Cutworms are small, brown or black caterpillars that can be found on the underside of the leaves of coriander plants. They feed on the leaves of the plant, and can cause damage to the stems and leaves.
Downy Mildew: Downy mildew is a fungal disease that can cause yellowing and wilting of the leaves of coriander plants. It is caused by the fungus Peronospora parasitica and is spread by splashing water.
Bacterial Leaf Spot: Bacterial leaf spot is a bacterial disease that can cause yellowing, wilting, and brown spots on the leaves of coriander plants. It is caused by the bacterium Xanthomonas campestris and is spread by splashing water.
Anthracnose: Anthracnose is a fungal disease that can cause yellowing, wilting, and dark, sunken spots on the leaves and stems of coriander plants. It caused by fungus Colletotrichum spp. and is spread by splashing water.
Root Rot: Root rot is a fungal disease that can cause yellowing, wilting, and rotting of the roots of coriander plants. It is caused by the fungus Fusarium oxysporum and is spread by splashing water.
Powdery Mildew: Powdery mildew is a fungal disease that can cause white, powdery growth on the leaves of coriander plants. It is caused by the fungus Erysiphe cichoracearum and is spread by splashing water.
Coriander is an annual herb that is most commonly used in its dried form as a spice. Harvesting coriander is a relatively straightforward process. The leaves and stems may be harvested at any time during the growing season, but it is best to do so when the plant is in full bloom. The leaves and stems should be cut close to the ground, leaving a few inches of stem for regrowth. The stems can be dried and used as a flavoring for soups, salads, and other dishes. The seeds can be harvested when they are ripe and dried for use in cooking or to make coriander essential oil.For fresh leaves it can be harvested when they reach a mature size, which is usually around 10-12 inches in height. To harvest, simply snip off the leaves at their base and remove any that are yellowing or wilting. The best time to harvest is early in the morning when the leaves are at their freshest.
Coriander leaves: The yield of coriander leaves for a hectare is around 6,000–8,000 kg. Irrigated grains: The yield of irrigated grains for a hectare is around 30–50 quintals. Rainfed grains: The yield of rainfed grains for a hectare is around 20–35 quintals.
