Coriander Farming Guide

1. Climate and Soil

• Climate: Cool and dry climate best. High heat at flowering reduces seed quality.
• Temperature: 15–25°C ideal.
• Soil: Well-drained loamy soil with organic matter.
  
  • pH: 6.0–8.0
  • Avoid waterlogging soil.

2. Land Preparation

• Plough 2–3 times to make the soil fine and weed-free.
• Apply 10–15 tons/acre of well-decomposed FYM (Farm Yard Manure) before sowing.
• Prepare raised beds in areas with heavy rainfall.

3. Seed and Sowing

• Seed rate: 10–15 kg/acre.
• Seed treatment: Treat with Trichoderma or Carbendazim (2 g/kg) for disease prevention.
• Seeds are split before sowing (for better germination).
• Spacing:
  
  • Row to row: 30 cm
  • Plant to plant: 10 cm
• Sowing depth: 2–3 cm

4. Irrigation

• First irrigation immediately after sowing.
• Subsequent irrigations every 7–10 days (depending on soil & weather).
• Avoid water stagnation.
• Stop irrigation 2 weeks before harvesting.

5. Manures and Fertilizers

• Apply 20:30:20 kg NPK per acre.
• Half nitrogen at sowing, half after 30 days.
• Spray micronutrients (Zn, Fe, B) if deficiency symptoms appear.

6. Weed and Pest Management

• Weeding: First weeding after 20–25 days, then one every 15 days.
• Common pests:
  
  • Aphids → Spray neem oil or Imidacloprid.
  • Leaf-eating caterpillar → Spray Spinosad.
• Diseases:
  
  • Powdery Mildew → Spray wettable sulphur.
  • Wilt → Use disease-free seeds, crop rotation.

7. Harvesting

• For leaves (Dhania Patta): Harvest 30–40 days after sowing; can be cut 2–3 times.
• For seeds (Coriander spice): Harvest when 50–60% of seeds turn yellowish-brown.
