Agriculture Geography

📖 Agro-climatic zones

India is divided into 15 broad agro-climatic zones by the Planning Commission (now under NITI Aayog's successor framework), based on soil type, climate, rainfall, and cropping patterns — a framework used for regional agricultural planning.

🌾 Cropping pattern by region

Rice — dominant in high-rainfall, alluvial regions: West Bengal, Punjab, Andhra Pradesh, Tamil Nadu.
Wheat — dominant in the Northern Plains with moderate winter rainfall: Uttar Pradesh, Punjab, Haryana, Madhya Pradesh.
Cotton — grown mainly on black soil in Maharashtra, Gujarat.
Sugarcane — needs high water availability: Uttar Pradesh, Maharashtra.
Tea — needs well-drained, acidic soil and high rainfall: Assam, West Bengal (Darjeeling), and parts of South India.

💧 Irrigation's role

Irrigation has significantly modified the natural geography of cropping — for example, canal irrigation and tube wells have allowed wheat and rice cultivation to expand into relatively drier Punjab and Haryana, well beyond what rainfall alone would support.

💡 Key Facts

India is divided into 15 agro-climatic zones for agricultural planning.
Cotton cultivation is strongly linked to black (Regur) soil in Maharashtra and Gujarat.
Irrigation (canals, tube wells) has allowed water-intensive crops to expand into naturally drier regions like Punjab.
Tea requires high rainfall and acidic, well-drained soil — hence its concentration in Assam and Darjeeling.

15 agro-climatic zones — planning framework based on soil, climate, rainfall.
Rice (high rainfall/alluvial) / Wheat (Northern Plains) / Cotton (black soil) / Sugarcane (high water) / Tea (acidic soil, high rainfall).
Irrigation modifies natural cropping geography — e.g. Punjab's rice cultivation despite lower natural rainfall.
