📌 CDS Focus 2022–2026: Agriculture is very high-yield. Exam tests: which crop grows in which season (Kharif/Rabi/Zaid), leading producing states (rice = WB; wheat = UP; cotton = Gujarat; jute = WB; tea = Assam), growing conditions (temperature & rainfall requirements), and Agricultural Revolutions (Green = HYV seeds; White = milk; Blue = fish; Yellow = oilseeds). Memorise crop→season→state→soil as a four-column table.

MAJOR CROPS OF INDIA
2. Major Crops — Growing Conditions & Leading States
Fig. 2.1 — Major Crops: Season, Soil, Temperature & Top Producing State
⚠️ Crop Traps — Most Tested: (1) Rice #1 state = West Bengal (not Punjab or UP — they are #2/#3). (2) Wheat #1 state = Uttar Pradesh (not Punjab, which is #2). (3) Cotton = Gujarat #1; grows best in black/regur soil. (4) Jute = West Bengal #1 (Golden Fibre, needs high humidity and alluvial delta soil). (5) Tea = Assam #1 (not Darjeeling — which is famous for quality, not quantity). (6) Coffee = Karnataka #1; Arabica coffee = Coorg (Kodagu). (7) Rubber = Kerala #1 (not NE India). (8) India is the world's largest producer of Milk, Spices, Pulses, Jute, Tea, and Bananas.
AGRICULTURAL REVOLUTIONS
3. Agricultural Revolutions of India
Fig. 3.1 — Major Agricultural Revolutions: What, Who, When & Key Outcome
💡 Green Revolution — Key Facts: Introduced HYV (High-Yielding Variety) seeds, chemical fertilisers, pesticides, and irrigation. Most successful for wheat in Punjab, Haryana & UP. Father: M.S. Swaminathan. Norman Borlaug introduced HYV wheat globally. Critics: Led to soil degradation, groundwater depletion, reduction in crop diversity.
IRRIGATION
4. Irrigation in India
💧 Traditional Irrigation
Canal Irrigation: Most extensive in India; mostly in northern plains (Indo-Gangetic Plain). Inundation canals (seasonal) and Perennial canals (year-round). UP = largest canal network
Wells & Tubewells: Most important source of irrigation in India (~60% of irrigated area). Mostly in alluvial areas of UP, Bihar, Rajasthan
Tank Irrigation: Predominant in peninsular India (AP, TN, Karnataka) where rocky terrain prevents canals. Ancient system
💧 Modern / Efficient Irrigation
Drip Irrigation (Trickle): Water delivered drop by drop directly to root zone. Best for orchards, vineyards, horticulture. Maharashtra = largest drip irrigation area. Saves 30–50% water
Sprinkler Irrigation: Water sprayed like rain. Ideal for uneven terrain and sandy soils. Used for vegetables, wheat, sugarcane. Rajasthan & AP have large sprinkler coverage
Rainwater Harvesting: Collecting and storing rainwater. Traditional forms: Kund, Baoli, Johad (Rajasthan); Bamboo drip (NE India)
Topic EKey Government Schemes in Agriculture
PM-KISAN
Pradhan Mantri Kisan Samman Nidhi — Rs 6,000/year direct income support to all eligible farmers in three equal installments.
PMFBY
Pradhan Mantri Fasal Bima Yojana — Crop insurance scheme at low premiums. Launched 2016. Covers pre-sowing to post-harvest losses.
MSP
Minimum Support Price — Government-guaranteed price for agricultural produce to protect farmers from market price crashes. CACP recommends MSP.
e-NAM
National Agriculture Market — Online pan-India trading platform for agricultural commodities. Links existing APMC mandis.
MGNREGS
Mahatma Gandhi NREGS — Guarantees 100 days of unskilled rural employment per year per household. Supports agricultural labour during lean seasons.
Q1. Which state is the largest producer of Rice in India? CDS PYQ
(a) Punjab(b) Uttar Pradesh(c) West Bengal(d) Andhra Pradesh
✔ Answer: (c) West Bengal
West Bengal is consistently India’s largest producer of rice by quantity, followed by Uttar Pradesh, Punjab, and Andhra Pradesh. Punjab produces the highest yield per hectare but West Bengal leads in total production due to its large cultivated area and three crops per year (aus, aman, boro seasons). Rice needs 25–35°C temperature and over 100 cm of rainfall.
Q2. “Operation Flood” was associated with which Agricultural Revolution? CDS PYQ
(a) Green Revolution(b) White Revolution(c) Blue Revolution(d) Yellow Revolution
✔ Answer: (b) White Revolution
Operation Flood (1970–1996) was launched by the National Dairy Development Board (NDDB) under Dr. Verghese Kurien, known as the “Father of the White Revolution.” It transformed India from a milk-deficit country to the world’s largest milk producer. It established the Amul cooperative model. M.S. Swaminathan is the Father of the Green Revolution (HYV seeds, wheat).
Q3. Black soil (Regur) is most suitable for growing which crop? CDS PYQ
(a) Rice(b) Wheat(c) Tea(d) Cotton
✔ Answer: (d) Cotton
Black soil (Regur), formed from Deccan Trap basalt, is the ideal soil for cotton cultivation. It has high water-retention capacity, self-ploughing (cracks when dry, swells when wet), and is rich in calcium, potassium, and magnesium. Maharashtra, Gujarat, and Telangana (Deccan Plateau) are major cotton growers due to this soil. This is why cotton is also called “black gold.”
Q4. Jute is called the “Golden Fibre.” Which state is the largest producer? ⚡ Tricky
(a) Assam(b) Odisha(c) Bihar(d) West Bengal
✔ Answer: (d) West Bengal
West Bengal accounts for about 50–60% of India’s jute production. Jute needs alluvial delta soil, high humidity (>80%), and over 150 cm of rainfall — conditions found in the Ganga–Brahmaputra delta. Assam is #2. India is the world’s largest producer of raw jute. Jute mills are concentrated in the Hugli River basin (West Bengal). Common trap: Assam for tea and jute are both high, but jute leader = West Bengal.
Q5. Arabica coffee, considered the finest variety, is mainly grown in which region? ⚡ Tricky
(a) Nilgiris, Tamil Nadu(b) Coorg (Kodagu), Karnataka(c) Wayanad, Kerala(d) Visakhapatnam hills, Andhra Pradesh
✔ Answer: (b) Coorg (Kodagu), Karnataka
Arabica coffee, considered superior in quality, is grown mainly in Coorg (Kodagu) district of Karnataka at altitudes of 1,000–1,500 m. Karnataka produces about 70% of India’s coffee. Robusta coffee (hardier, used in instant coffee) is grown at lower elevations in Kerala and Tamil Nadu. India exports coffee mainly to Europe and Russia.
Q6. The HYV (High-Yielding Variety) seeds introduced in the Green Revolution were primarily for which crops? CDS PYQ
(a) Rice and Maize only(b) Wheat and Rice(c) Cotton and Sugarcane(d) All Kharif crops
✔ Answer: (b) Wheat and Rice
The Green Revolution (1960s–1970s) primarily used HYV seeds of wheat and rice developed by Norman Borlaug (wheat) and IR-8 rice (IRRI). The revolution was most successful for wheat in Punjab and Haryana. M.S. Swaminathan adapted these varieties for Indian conditions. The revolution tripled wheat production and doubled rice production but led to regional imbalances, groundwater depletion, and soil degradation.
