Agriculture in India

Overview

Agriculture forms the backbone of the Indian economy, employing nearly half of the country's workforce and contributing significantly to GDP. For the KAR TET Paper II Social Studies section, this topic connects geography (climate, soil, water) with economics (livelihood, trade) and carries direct questions on types of farming, major crops, and agricultural practices across India.

Students must master the classification of agriculture (subsistence vs commercial, intensive vs extensive), understand which crops grow in which regions and why, and know the key agricultural practices that have transformed Indian farming since independence. Karnataka-specific agricultural knowledge—major crops, irrigation sources, and farming challenges—often appears in state-level TET exams.

This topic also links to broader themes like food security, rural development, and sustainable practices, making it essential for understanding India's socio-economic fabric.

Key Concepts

• **Subsistence agriculture** means farming primarily to feed the farmer's family, with little surplus for sale. Most small and marginal farmers in India practise this.

• **Commercial agriculture** involves large-scale production of crops for sale in markets, often using modern inputs like HYV seeds, fertilisers, and machinery.

• **Intensive agriculture** uses high labour and capital inputs on small landholdings to maximise yield per hectare. Common in densely populated areas like West Bengal and Kerala.

• **Extensive agriculture** covers large areas with minimal labour input per hectare, yielding less per unit area but more total output. Seen in parts of Punjab for wheat.

• **Kharif crops** are sown with the onset of monsoon (June-July) and harvested in autumn (September-October). Examples: rice, maize, jowar, bajra, cotton, sugarcane.

• **Rabi crops** are sown in winter (October-November) and harvested in spring (March-April). Examples: wheat, barley, gram, mustard, peas.

• **Zaid crops** are short-duration summer crops grown between rabi harvest and kharif sowing. Examples: watermelon, cucumber, moong, urad.

• **Green Revolution** (1960s onwards) introduced HYV seeds, chemical fertilisers, irrigation, and modern techniques, dramatically increasing wheat and rice production in Punjab, Haryana, and western UP.
