Indian Agriculture
Regional Specialization:

Crop Seasons in India:
| Season | Period | Crops | Water Source |
|---|---|---|---|
| Kharif | June-Oct | Rice, cotton, jute, millets | Monsoon (rainfed + irrigation) |
| Rabi | Oct-March | Wheat, chickpeas, mustard | Irrigation, stored moisture |
| Zaid | Mar-June | Vegetables, melons, fodder | Irrigation |
Green Revolution Impact:
| Aspect | Before 1960s | After Green Revolution |
|---|---|---|
| Wheat yield | ~700 kg/ha | ~3000+ kg/ha |
| Rice yield | ~1000 kg/ha | ~2500+ kg/ha |
| Total foodgrain | 50 million tonnes | 300+ million tonnes |
| HYV coverage | <5% | >80% wheat/rice area |
Problems of Indian Agriculture:
| Problem | Description | Impact |
|---|---|---|
| Small landholdings | 86% holdings <2 ha | Fragmented, uneconomical |
| Low productivity | Yield/area below potential | Income low |
| Dependence on monsoon | Rainfed agriculture prevalent | Production uncertainty |
| Lack of mechanization | Small farms, poverty | Labor-intensive |
| Marketing issues | Storage, transport, MSP | Post-harvest losses |
⚡ BPSC PYQ: “Discuss the impact of Green Revolution on Indian agriculture” Answer: The Green Revolution transformed Indian agriculture through introduction of HYV seeds (especially wheat and rice), chemical fertilizers, irrigation, and mechanization. Production increased dramatically making India self-sufficient in foodgrain. However, it also caused regional disparities, environmental issues (water depletion, pesticide pollution), and dependence on purchased inputs.
