219. Agriculture

The Kharif-rabi-zaid cropping calendar is the working skeleton of Indian agriculture. Kharif crops use the southwest monsoon; paddy, cotton, jute, jowar, bajra and tur are sown with June-September rainfall, though irrigation can modify the exact district pattern. Rabi crops use cool winter temperatures and stored water, so wheat, gram and mustard depend on canal releases, tube-wells or conserved soil moisture after the monsoon. Zaid crops occupy the short April-June interval between rabi harvest and kharif sowing, especially vegetables, fodder and cucurbits under irrigation. Rajasthan turns this national calendar into a sharp contrast: bajra in Barmer, Jaisalmer and Nagaur is a kharif dryland crop, while mustard and wheat in Sri Ganganagar, Hanumangarh and Bharatpur are winter crops tied to canals and wells. The same calendar also separates rainfed farming from irrigated farming. NCERT classifies farming by soil moisture adequacy during the crop season; that distinction explains why weak monsoon years first reduce rainfed pulses and millets, while irrigated wheat reacts later through reservoir storage and canal supply. Crop names alone are therefore incomplete geography. A complete agricultural region carries season, water source, soil, district and market together. Seasonal timing also explains why shifting-cultivation names cannot be used as Rajasthan examples: Pondu in Odisha, Poonam in Kerala and Jhoom in Assam-type north-eastern usage rely on forest fallow, slope and heavy rain, while Thar villages rely on bunding, hardy seed and livestock manure. In dry years, fodder availability often becomes as important as grain output because cattle, sheep and goats absorb the shock in western Rajasthan. This livestock link is central to arid agriculture and drought recovery.
