Rice — The Staple of India
India is the second-largest producer of rice in the world (after China), producing about 120 million tonnes annually from ~44 million hectares.

Varieties
- Aman (winter rice): Rainfed; sown June-July, harvested Nov-Dec — 60% of India’s rice
- Aus (autumn rice): 3-4 month variety; May to Oct — East India
- Boro (summer rice): Irrigated; Nov-Dec to April-May — West Bengal, Assam
- Basmati: Premium aromatic rice; Punjab, Haryana, Western UP (GI tagged)
Cultivation Methods
- Transplanting: Seedlings grown in nurseries for 25-35 days; then transplanted to puddled fields
- SRI (System of Rice Intensification): Less water, wider spacing, higher yields
- Direct seeded rice (DSR): Growing popularity in Punjab; less labor, but higher weed risk
Wheat — The Winter Staple
India is the second-largest producer of wheat in the world (after China), with an annual output of about 110 million tonnes from ~31 million hectares.
Geographic Requirements
| Factor |
Requirement |
| Temperature |
10-15°C at sowing; 25-30°C at harvest |
| Rainfall |

| Season |
Rabi (winter) — sown Oct-Dec, harvested March-April |
The Green Revolution Story
Wheat production surged from 12 million tonnes (1965) to 110 million tonnes today — most dramatic yield increase in Indian agricultural history.
Key factors: Norman Borlaug’s dwarf wheat varieties (Lerma Rojo, Sonora 64), irrigation expansion in Punjab-Haryana, chemical fertilizers, assured MSP, government procurement.
