Describe rice production and major areas of rice production in India.

Introduction: Rice (Oryza sativa) is India's principal staple Kharif cereal crop, feeding over 65% of the population. India is the world's second-largest producer (after China) and the largest exporter of rice globally, accounting for ~130–135 million tonnes of annual production.

1. Geographical Requirements for Rice Cultivation:

• Temperature: Tropical/sub-tropical climate requiring high temperature ($22^circ ext{C}$ to $32^circ ext{C}$) and abundant sunshine during maturation.
• Rainfall: High rainfall of 100 to 200 cm; standing water (5–10 cm) required during transplanting and early growth stages.
• Soil: Deep, fertile clayey loam and alluvial soils with impervious clay subsoils retaining moisture.

2. Major Rice Producing Areas & States in India:

• 1. West Bengal (Leading Producer - ~14–15% output):
  • Ganges delta and Burdwan district (known as the "Rice Bowl of Bengal"); cultivates 3 crops annually—Aus (Autumn), Aman (Winter), and Boro (Summer).
• 2. Uttar Pradesh (~12–13%): Terai belt and fertile eastern alluvial districts (Gorakhpur, Varanasi).
• 3. Punjab & Haryana (High-Yield Green Revolution Belts):
  • Highest per-hectare productivity (>4,000 kg/ha) driven by tubewell/canal irrigation; leading exporters of aromatic Basmati Rice.
• 4. Coastal Deltas & Peninsular Plains:
  • Andhra Pradesh (Krishna-Godavari Delta - Rice Bowl of South India), Telangana, Odisha (Mahanadi delta), and Tamil Nadu (Kaveri Delta).
• 5. Madhya Pradesh: Balaghat (famous for Chinnor Rice - GI Tag), Katni, Rewa, and Seoni.

Conclusion: Rice cultivation underpins national food security and agrarian employment, with sustainable transitions needed toward Direct Seeded Rice (DSR) to conserve groundwater.
