Indian agriculture is a guaranteed 3-6 question block in PSC exams. Crop seasons, revolution names and their fathers, and soil types are the most repeated topics. This note covers everything.
Crop Seasons in India
| Season | Sowing | Harvesting | Also Called | Key Crops |
|---|---|---|---|---|
| Kharif | June-July (onset of SW monsoon) | Sept-Oct | Monsoon crop | Rice, Jowar, Bajra, Maize, Cotton, Jute, Sugarcane, Groundnut, Soybean |
| Rabi | Oct-Nov (after monsoon) | March-April | Winter crop | Wheat, Barley, Gram (Chana), Mustard, Peas, Linseed |
| Zaid | March-April | June-July | Summer crop | Watermelon, Muskmelon, Cucumber, Moong dal, Vegetables |
Memory trick: Kharif = Khareef (monsoon in Arabic) = rain-dependent. Rabi = Rabi (spring in Arabic) = winter sowing. Zaid = Zwischensaison (between seasons).
Major Crops — Leading States
| Crop | #1 Producer State | Key Facts |
|---|---|---|
| Rice | West Bengal | Kharif crop; India = #2 global producer (after China) |
| Wheat | Uttar Pradesh | Rabi crop; India = #2 global producer (after China) |
| Sugarcane | Uttar Pradesh | Tropical/subtropical; takes 12 months to mature; India = #2 producer (after Brazil) |
| Cotton | Gujarat | ”White gold”; Kharif; India = #2 producer (after China) |
| Jute | West Bengal | ”Golden Fibre”; Kharif; needs humid climate; India = #1 producer globally |
| Tea | Assam | Plantation; India = #2 producer (after China); Assam > West Bengal > Tamil Nadu |
| Coffee | Karnataka | Plantation; Karnataka produces ~70% of Indian coffee |
| Rubber | Kerala | ~90% of India’s rubber; Kottayam = rubber capital |
| Groundnut | Gujarat | Kharif oilseed |
| Soybean | Madhya Pradesh | Kharif oilseed |
| Mustard | Rajasthan | Rabi oilseed |
| Coconut | Kerala | Perennial; Kerala = #1 |
| Tobacco | Gujarat/Andhra Pradesh | |
| Maize | Karnataka | Kharif; used as feed grain |
PSC trick: For “largest producer” questions, remember: UP = wheat, sugarcane. WB = rice, jute. Gujarat = cotton, groundnut. Karnataka = coffee. Kerala = rubber, coconut. Assam = tea.
Agricultural Revolutions
| Revolution | Sector | Father/Associated Person | Year/Period |
|---|---|---|---|
| Green Revolution | Food grains (wheat, rice) | Dr. M.S. Swaminathan (India); Norman Borlaug (global) | 1960s-70s |
| White Revolution (Operation Flood) | Milk/Dairy | Dr. Verghese Kurien | 1970-96 |
| Blue Revolution | Fisheries/Aquaculture | Dr. Arun Krishnan / Dr. Hiralal Chaudhuri | 1985-90 |
| Yellow Revolution | Oilseeds | Sam Pitroda (some sources: Rajiv Gandhi era policy) | 1986-90 |
| Golden Revolution | Horticulture/Honey/Fruits | Nirpakh Tutej | 1991-2003 |
| Silver Revolution | Eggs/Poultry | Indira Gandhi (policy push) | 1970s |
| Pink Revolution | Meat/Prawns/Onion | Durgesh Patel | — |
| Brown Revolution | Leather/Non-conventional energy/Cocoa | — | — |
| Black Revolution | Petroleum/Crude oil | — | — |
| Grey Revolution | Fertilizers | — | — |
| Round Revolution | Potato | — | — |
| Rainbow Revolution | Overall agriculture | — | 2000s |
| Evergreen Revolution | Sustainable agriculture | M.S. Swaminathan | Proposed concept |
Top 3 PSC revolutions: Green = M.S. Swaminathan (food grains). White = Verghese Kurien (milk, Operation Flood). Blue = fisheries. These three are asked in almost every exam.
Green Revolution — Detail
| Fact | Detail |
|---|---|
| Key feature | High Yielding Variety (HYV) seeds, chemical fertilizers, irrigation, mechanization |
| Crops impacted | Mainly wheat (then rice) |
| States benefited most | Punjab, Haryana, Western UP |
| HYV wheat varieties | Sonora-64, Lerma Rojo (from Mexico, via Norman Borlaug) |
| HYV rice | IR-8 (“Miracle Rice”) |
| Criticism | Regional inequality, ecological damage, water table depletion, input-intensive |
White Revolution / Operation Flood
| Fact | Detail |
|---|---|
| Father | Dr. Verghese Kurien (“Milkman of India”) |
| Organisation | AMUL (Anand Milk Union Limited); NDDB (National Dairy Development Board) |
| Based in | Anand, Gujarat |
| Phases | Phase I (1970-80), Phase II (1981-85), Phase III (1985-96) |
| Result | India became world’s #1 milk producer |
Soil Types in India
| Soil Type | Colour/Feature | Found In | Suitable For |
|---|---|---|---|
| Alluvial | Most widespread; fertile; river-deposited | Indo-Gangetic plains, river deltas | Rice, wheat, sugarcane, most crops |
| Black (Regur) | Black; retains moisture; cracks when dry | Deccan Plateau (Maharashtra, MP, Gujarat) | Cotton (“Black Cotton Soil”) |
| Red | Red due to iron oxide | Tamil Nadu, Chhattisgarh, Odisha, Karnataka | Millets, groundnut, tobacco |
| Laterite | Red; acidite; leached; hard when dry | Kerala, Karnataka, NE India, hill slopes | Tea, coffee, cashew, rubber |
| Desert/Arid | Sandy; low humus; high salt | Rajasthan, Gujarat (Kutch) | After irrigation: bajra, jowar |
| Forest/Mountain | Acidic; humus-rich | Himalayan slopes, Western Ghats | Plantation crops, spices |
| Saline/Alkaline | High salt; infertile | Arid regions, coastal areas | Needs reclamation (gypsum treatment) |
| Peaty/Marshy | Organic; waterlogged | Kerala (Kuttanad), Sundarbans | Rice (with management) |
Kerala’s soil: Predominantly Laterite (most of Kerala) and Peaty/Marshy (Kuttanad). Alluvial soil in river valleys. Laterite = good for rubber, tea, coffee.

| Well/Tube Well | Groundwater extraction; most common source | Punjab, UP, Rajasthan |
| Tank | Traditional rainwater storage | Tamil Nadu, Andhra Pradesh, Karnataka |
| Drip | Water-efficient; drop by drop to roots | Maharashtra, Gujarat (promoted in arid areas) |
| Sprinkler | Water sprayed; for undulating terrain | Rajasthan, Gujarat |
Major Irrigation Projects / Dams
