Onion farming की complete guide — varieties, Rabi/Kharif calendar, nursery, fertilizer, pest management और storage economics।
Onion (Allium cepa) is India's most price-volatile and politically sensitive vegetable crop — onion price spikes have toppled state governments. India is the world's second-largest onion producer and largest exporter, with Maharashtra, Madhya Pradesh, Karnataka and Gujarat leading production. For Indian farmers, onion offers high profitability but requires precise management of timing, nutrition and storage.
Onion (Pyaz) भारत की सबसे price-volatile और politically sensitive vegetable crop है। India दुनिया का second-largest onion producer और largest exporter है। Farmers के लिए high profitability लेकिन precise management ज़रूरी है।

🌍 Climate & Soil Requirements
Climate और Soil Requirements
- Temperature: 13–35°C. Bulb formation needs short days and cool temperatures (below 25°C). Very high temperatures during bulbing cause poor quality.
- Rainfall: 650–750mm well-distributed. Irrigation dependent in most regions. Excess rain during maturity causes neck rot and poor storage quality.
- Soil: Well-drained sandy loam to clay loam, rich in organic matter. pH 6.0–7.5. Poorly drained soils cause bulb rot. Raised beds mandatory in flat areas.
- Major producing states: Maharashtra (Nashik — "Onion Capital of India"), Madhya Pradesh, Karnataka, Gujarat, Bihar, Andhra Pradesh, Rajasthan.

🌱 Nursery Raising & Transplanting

💧 Irrigation & Fertilizer
Irrigation और Fertilizer
Irrigation
- First irrigation immediately after transplanting. Then every 7–10 days during vegetative growth.
- Critical: Increase frequency to every 5–7 days during bulb development (60–90 days after transplant).
- Stop irrigation 10–15 days before harvest — essential for neck drying, good storage quality and easy harvesting. This step is critical and often missed.
- Drip irrigation: Saves 40% water, reduces foliar disease, enables precise fertigation.
Fertilizer
| Timing | N (kg/ha) | P (kg/ha) | K (kg/ha) | Application |
|---|---|---|---|---|
| Basal (at transplanting) | 50 | 50 | 50 | Full P+K + 1/3 N — mix into soil |
| 30 days after transplant | 50 | — | — | 1/3 N top dressing + 2% urea foliar |
| 60 days after transplant | 50 | — | 25 | Remaining N + K for bulb development |
🐛 Pest & Disease Management
Pest और Disease Management
| Problem | Symptoms | Management |
|---|---|---|
| 🍄 Purple Blotch | Purple lesions on leaves — most serious fungal disease | Mancozeb 2.5g/L spray every 10 days from 30 days after transplant |
| 🍄 Stemphylium Blight | Yellow oval spots with purple border | Iprodione or Mancozeb spray |
| 🦟 Thrips | Silver-white streaks on leaves, curling | Spinosad or Fipronil spray. Yellow sticky traps. |
| 🍄 Basal Rot (Fusarium) | Yellowing + rotting at base | Carbendazim soil drench, avoid waterlogging |
| 🔴 Neck Rot (Botrytis) | Rotting at neck after harvest | Proper field curing before storage, avoid irrigation near harvest |
🌾 Harvesting, Curing & Storage
Harvesting, Curing और Storage
- Harvest indicator: 50–75% of tops (leaves) fallen/bent, bulb neck is thin and dry. Harvesting too early = poor storage. Too late = field rot.
- Harvest method: Loosen soil with fork, pull bulbs by hand. Avoid bruising — any bruise point becomes rot during storage.
- Field curing (essential!): Spread harvested bulbs in field for 7–10 days with leaves covering bulbs (protects from sun). This dries the neck completely — critical for storage quality.
- Storage (onion chawl): Store in well-ventilated shade structure. Traditional bamboo/wood platforms with gaps for airflow. Maintain 65–70% humidity. Avoid cold storage for red onions — causes sprouting.
- Yield: Rabi — 20–35 tonnes/ha. Kharif — 15–25 tonnes/ha.
