Class 10 Social Science Notes — Chapter 8: Agriculture
Types, cropping seasons, major crops, and impact of reforms and globalisation.
Detailed NCERT notes
- Agriculture employs ~50% of India's workforce but contributes a smaller share of GDP.
- Types of farming:
- Primitive subsistence — slash and burn, small patches (jhumming in NE, podu in Odisha).
- Intensive subsistence — small landholdings, high labour, multiple cropping; dominant in India.
- Commercial farming — high inputs (HYV seeds, fertilisers, mechanisation), market oriented.
- Plantation — single-crop, large area, capital-intensive (tea, coffee, rubber).
- Cropping seasons: Kharif (June–October, monsoon; rice, maize, jowar, bajra, cotton, jute, groundnut), Rabi (October–April, winter; wheat, gram, mustard, peas, barley), Zaid (short summer; watermelon, muskmelon, cucumber, fodder).
- Major crops:
- Rice — Kharif; needs high temperature (>25 °C) and rainfall (>100 cm); West Bengal, UP, Punjab, Andhra, Bihar.
- Wheat — Rabi; cool growing (10–15 °C), moderate rainfall; Punjab, Haryana, UP, MP.
- Millets — Jowar, Bajra, Ragi; drought resistant; Maharashtra, Karnataka, Rajasthan, Tamil Nadu.
- Sugarcane — tropical/subtropical; UP largest, followed by Maharashtra, Karnataka, Tamil Nadu.
- Cotton — kharif; needs black soil, 210 frost-free days; Maharashtra, Gujarat, MP.
- Tea and coffee — plantation; Assam, WB (tea); Karnataka, Kerala, TN (coffee).
- Green Revolution (mid-1960s onwards): HYV seeds, chemical fertilisers, irrigation and machinery → self-sufficiency in food grains, especially in Punjab, Haryana, western UP.
- White Revolution (Operation Flood): made India the world's largest milk producer.
- Institutional reforms: land ceiling, consolidation of holdings, abolition of zamindari, cooperative farming; Kisan Credit Card, PMFBY (crop insurance).
- Impact of globalisation: cheap imports (edible oils), contract farming with MNCs, shift to cash crops → income volatility for small farmers; farmer distress, migration.
- Food security: PDS (public distribution system), buffer stocks via FCI, minimum support prices (MSP).
Formulas & key results
Mind map
- Types: primitive/intensive/commercial/plantation
- Seasons: kharif/rabi/zaid
- Major crops and regions
- Green Revolution + White Revolution
- Reforms + globalisation impact
Tricks & shortcuts
- Kharif = monsoon (rice); Rabi = winter (wheat); Zaid = summer (watermelon).
- Green Revolution belt = Punjab/Haryana/W-UP.
Common mistakes to avoid
- Confusing horticulture with plantation.
- Mixing kharif and rabi crops.
Competency-based questions & answers
- Q. How has globalisation impacted Indian agriculture?A. Opened markets to cheap imports; boosted cash crops and contract farming with MNCs; but small farmers face volatile prices, higher input costs and debt.
- Q. Why did India need a Green Revolution?A. Frequent food shortages, dependence on imports, drought vulnerability in the 1960s — HYV seeds + irrigation + fertilisers boosted output, giving self-sufficiency in wheat and rice.
