Climate
■ Coriander is a tropical crop and can be successfully grown in the rage season in areas free of severe frost during the flowering and fruit set phases.
■ The dry and cold climate favors higher seed production. Cloudy weather during the flowering and fruiting phases increases the incidence of pests and diseases. However, the timing of planting varies in different places in India.
■ In West Bengal and Uttar Pradesh, seeds are sown during the rabi season, in Maharashtra during kharif, in Tamil Nadu in kharif and rabi, and in Karnataka from May to August and from October to January.
Soil
■ Coriander is grown both irrigated and rainwater. Being an irrigated crop, cilantro can be grown in almost any soil type, as long as enough compost is applied. A rain-fed crop can only be grown in heavier soil types that have a better water-holding capacity. The crop is best grown on heavy, black, cotton loamy soils and rich silty clays that are well drained with distributed moisture. Saline, alkaline and sandy these types of soils are not suitable.

■ Coriander propagates by seed. Before sowing the fruits are rubbed until the two mesocarps are separated and then they are sown.
Fertilizers and Manures:
■ Approximately 10-20 tons of FYM per hectare are applied to the field long before planting.
■ Fertilizers are applied at 40:40:40 or 30:40:20 kg or 15:40:20 or 35:35:35 or 20:30:20 NPK per hectare depending on location at planting time.
Irrigation
■ The crop is watered immediately after sowing to ensure uniform germination and then watered at intervals of 7-10 days, depending on the soil and climatic conditions.
Intercultural
■ The crop requires two or three weeds. The first weeding, hoeing and grounding should be done 40-45 days after sowing, when the seedlings are well above the ground.
■ Weeds can be controlled by applying pendimethalin or fluchloralin at 1.5 kg or 5-6 kg.
HARVESTED
■ The coriander plant matures in 90-120 days for cereals and 40 days for vegetables. Leaf plucking, up to 50%, when the harvest is between 60 and 75 days old, offers economic benefits
in irrigated conditions. The crop should not be allowed to become ripe as this will spoil the quality, especially the color of the product.
■ Harvesting should be done when the fruit or 50% of the seeds are fully ripe and begin to change from green to brown.
■ High yields can be achieved when plants are harvested at the stage where 100% fruit turns yellow.
YIELD
■ On average, a seed yield of 400 to 500 kg / ha can be achieved under rainfall of 1250 kg / ha under irrigated conditions.
Seed conservation
■ Whole and dried seeds are usually bagged and stored in a cool, dry room.
■ At the time of storage, the seeds should not contain more than 0.5-9% moisture..e seeds should not contain more than 0.5-9% moisture..

I discovered that I was infected with the virus 3 months ago, after a medical check-up. My doctor told me and I was shocked, confused and felt like my world had crumbled. I was dying slowly due to the announcement of my medical practitioner but he assured me that I could live a normal life if I took my medications (as there was no medically known cure to Herpes). I went from church to church but soon found that my case needed urgent attention as I was growing lean due to fear of dying anytime soon. In a bid to look for a lasting solution to my predicament, I sought for solutions from the herbal world.
