📍 Best Climate and Soil for Onion Cultivation
✅ Ideal Climate:
Onions grow well in cool and dry climates.
Temperature range: 13°C to 25°C is ideal during the growing stage.
High temperatures during maturity help in proper bulb formation and drying.
✅ Soil Requirements:
Light, well-drained loamy soil with good organic matter.
Soil pH should be between 6.0 and 7.5.
Avoid waterlogged or saline soils.
🚜 Land Preparation
Plough the land 2–3 times and bring it to fine tilth.
Add well-decomposed farmyard manure (20–25 tons/ha) before last ploughing.
Prepare raised beds or ridges and furrows for better drainage.

Rabi Season: October–December
Sowing time varies by region and weather. For maximum profit, time your crop to target high-price periods, especially during lean supply months.


🌱 Onion Planting Methods
Seedlings are raised in nurseries and then transplanted.
Seed rate: 8–10 kg per hectare for transplanting.
Transplant 6-week-old seedlings when they are 12–15 cm tall.
Spacing:
Row-to-row: 15–20 cm
Plant-to-plant: 10 cm
💧 Irrigation for Onion Crop
Onions need frequent but light irrigation.
Avoid waterlogging to prevent bulb rot.
Irrigate immediately after transplanting, then every 7–10 days depending on soil moisture.
Critical stages:
Bulb formation
Maturity (reduce watering for better shelf life)


🌿 Fertilizer Management
Apply 20 tons of organic manure before planting.
Recommended NPK dose: 100:50:50 kg/ha
Apply 50% Nitrogen + Full P + K at transplanting
Remaining Nitrogen in two splits at 30 and 45 days after transplanting
Add Micronutrients like Zinc and Boron if required.
🐛 Pest and Disease Management
Common Pests:
Thrips
Onion fly
Cutworms
Common Diseases:
Purple blotch
Downy mildew
Basal rot
Control Measures:
Use Neem-based bio-pesticides.
Spray Fipronil or Imidacloprid for thrips.
Practice crop rotation to avoid soil-borne diseases.


🔥 Weed Management
Weeds compete for nutrients, affecting bulb size.
Perform manual weeding or use pre-emergence herbicide like Pendimethalin.
🧅 Harvesting and Post-Harvest Handling
Harvest when 60–70% of leaves fall over naturally.
Cure onions under shade for 7–10 days.
Remove tops and roots, and grade bulbs by size.
Storage Tips:
Store in well-ventilated, dry places.
Use net bags or ventilated crates for long shelf life.
