Coriander

 The scientific name - Coriandrum sativum 

Coriander, known locally in Sri Lanka as "kottamalli," is a widely used herb and spice with both culinary and medicinal importance. Originating from the Mediterranean and widely adopted in South Asia, coriander plays a significant role in Sri Lankan cuisine. Its seeds and leaves are used to add a warm, earthy, and slightly citrusy flavor to various dishes, from curries to soups. Beyond its culinary uses, coriander is valued in traditional Sri Lankan medicine, known as Ayurveda, for its digestive and anti-inflammatory properties.

History

The history of coriander is lengthy and intriguing, dating back thousands of years. It was one among the first spices that people adopted in the Mediterranean and Middle East. Coriander was so highly prized by the ancient Egyptians that it was even placed in King Tutankhamun's tomb, indicating that it was used in religious ceremonies and may even have been believed to have protective properties.

In addition to using it as a spice, the Greeks and Romans also utilized coriander to make perfumes, flavor wines, and even believe it to be a medicinal herb. The Romans helped coriander spread throughout Europe and subsequently Asia, where it became a staple in Southeast Asian, Chinese, and Indian cooking customs.

Economic value of Coriander

The demand for coriander in cuisine, spice blends, and health goods around the world has given it substantial economic importance. Coriander seed exports from major producers like Morocco and India generate foreign exchange. Because it gives smallholder farmers a means of subsistence, it boosts rural economies. In addition to being employed in the culinary, pharmaceutical, and wellness industries, the spice is essential to the multibillion-dollar spice industry, which increases its economic significance.

Cultivetion

1. Climate and Soil : Coriander thrives in warm temperatures (18°C-30°C) and well-drained, fertile soil with a pH of 6.0-7.0.

2. Sowing and Planting : Seeds are sown directly or started in trays, spaced 1-2 inches apart with rows 6-8 inches apart, at a depth of 0.5-1 inch.

3. Watering and Fertilization : Regular, light watering is needed; avoid overwatering. Use balanced fertilizers or organic compost to enrich the soil.

4. Growth and Maintenance : Thin seedlings, weed regularly, and mulch to retain moisture. Control pests with organic methods like neem oil.

5. Harvesting : Harvest fresh leaves (cilantro) within 3-4 weeks, and seeds after 3-4 months when they turn dry and brown or yellow.

6. Post-Harvest Processing : Dry seeds in a cool, dry place and store in airtight containers; fresh cilantro leaves can be used immediately or refrigerated.
