Agriculture sector is foundation of Indian economy, employing 45% workforce despite 14% GDP share (low productivity). Structure: Large percentage smallholder farmers, Monsoon-dependent, Significant subsistence farming, Crop insurance emerging. Major crops: Rice, wheat, cotton, sugarcane, pulses; regional variations. Challenges: Low productivity (vs. global), Infrastructure gaps (irrigation, storage), Input costs rising (seeds, fertilizer), Market access issues, Climate vulnerability, Farmer indebtedness. Recent policies: Minimum support prices (MSP, floor prices), Crop insurance (PMFBY), Soil health cards, Drip irrigation promotion, Farmer income doubling target. Land holdings: Fragmented (average ~1.2 hectares), Underutilization, Inheritance pressures. Technology adoption: Slow (compared to industry), Government extension services improve. Rural infrastructure: Roads, electricity, water improving but gaps remain. Agricultural trade: India exporter of some crops (rice, cotton), Importer of others (pulses, vegetable oils). Farm income: Low and volatile, Drives migration to cities, Requires diversification. ICAI focus: Sector structure, challenges, policy responses. Exam tip: Agriculture productivity is key issue; mechanization, irrigation, better seeds, and market access are solutions.
