Chapter 4: Agriculture (Geography)

Introduction

India is an agriculturally important country: two-thirds of its population is engaged in agricultural activities. Agriculture is a primary activity that produces most of our food and raw material for industries; products like tea, coffee and spices are also exported. This chapter covers types of farming, cropping seasons, major crops and their growing conditions, and the reforms introduced to improve Indian agriculture.

Key Concepts

Types of farming

1. Primitive subsistence farming

  • Practised on small patches with primitive tools — hoe, dao and digging sticks — and family/community labour; depends on monsoon and natural soil fertility.
  • It is 'slash and burn' agriculture: farmers clear a patch, grow food crops, then shift when fertility falls; nature replenishes fertility. Productivity is low.
  • Names in India: jhumming (Assam, Meghalaya, Mizoram, Nagaland — the north-east), Pamlou (Manipur), Dipa (Bastar, Chhattisgarh, and Andaman & Nicobar), Bewar/Dahiya (Madhya Pradesh), Podu/Penda (Andhra Pradesh), Pama Dabi/Koman/Bringa (Odisha), Kumari (Western Ghats), Valre/Waltre (south-eastern Rajasthan), Khil (Himalayan belt), Kuruwa (Jharkhand).
  • Names abroad: Milpa (Mexico and Central America), Conuco (Venezuela), Roca (Brazil), Masole (Central Africa), Ladang (Indonesia), Ray (Vietnam).
  • The story of Rinjha, near Diphu in Assam, shows a family practising slash-and-burn with bamboo-canal irrigation from a spring.

    • 2. Intensive subsistence farming

  • In areas of high population pressure on land; labour-intensive, with high doses of biochemical inputs and irrigation.
  • The right of inheritance divides land among generations, making holdings uneconomical, yet farmers try to get maximum output.

    • 3. Commercial farming

  • Uses higher doses of modern inputs: HYV seeds, chemical fertilisers, insecticides and pesticides.
  • Commercialisation varies: rice is a commercial crop in Haryana and Punjab but a subsistence crop in Odisha.
  • Plantation is a type of commercial farming — a single crop on a large area, an interface of agriculture and industry, capital-intensive, with migrant labour. Examples: tea, coffee, rubber, sugarcane, banana; tea in Assam and North Bengal, coffee in Karnataka. Needs a well-developed transport and communication network.

    • Cropping seasons

  • Rabi — sown October to December, harvested April to June. Wheat, barley, peas, gram, mustard. Important states: Punjab, Haryana, Himachal Pradesh, Jammu and Kashmir, Uttarakhand, Uttar Pradesh. Winter rain from western temperate cyclones helps; the green revolution also helped.
  • Kharif — sown with the onset of monsoon, harvested September–October. Paddy, maize, jowar, bajra, tur (arhar), moong, urad, cotton, jute, groundnut, soyabean. In Assam, West Bengal and Odisha, three crops of paddy: Aus, Aman and Boro.
  • Zaid — short summer season between rabi and kharif: watermelon, muskmelon, cucumber, vegetables and fodder crops.
  • Sugarcane takes almost a year to grow.

    • Major crops and growing conditions

    Rice — staple food of most Indians; India is the second largest producer after China. Kharif; needs above 25°C, high humidity and rainfall above 100 cm. Grown in northern and north-eastern plains, coastal and deltaic regions; canals and tubewells allow it in Punjab, Haryana, western UP and parts of Rajasthan.

    Wheat — second most important cereal; rabi; needs a cool growing season and bright sunshine at ripening, 50–75 cm rainfall evenly distributed. Two zones: Ganga–Satluj plains (north-west) and black soil region of the Deccan. States: Punjab, Haryana, Uttar Pradesh, Madhya Pradesh, Bihar, Rajasthan.

    Millets — jowar, bajra, ragi: "coarse grains" with very high nutritional value (ragi is rich in iron, calcium, micronutrients and roughage).

  • Jowar — third most important food crop by area and production; rain-fed, grown in moist areas; Maharashtra, Karnataka, Andhra Pradesh, Madhya Pradesh.
  • Bajra — sandy and shallow black soils; Rajasthan, Uttar Pradesh, Maharashtra, Gujarat, Haryana.
  • Ragi — dry regions; red, black, sandy, loamy and shallow black soils; Karnataka, Tamil Nadu, Himachal Pradesh, Uttarakhand, Sikkim, Jharkhand, Arunachal Pradesh.

    • Maize — food and fodder; kharif; 21°C to 27°C; old alluvial soil; in Bihar also grown in rabi. States: Karnataka, Madhya Pradesh, Uttar Pradesh, Bihar, Andhra Pradesh, Telangana.

    Pulses — India is the largest producer and consumer of pulses; main protein source in vegetarian diets. Tur (arhar), urad, moong, masur, peas, gram. Need less moisture. As leguminous crops, all except arhar restore soil fertility by fixing nitrogen, so they are grown in rotation. States: Madhya Pradesh, Rajasthan, Maharashtra, Uttar Pradesh, Karnataka.

    Sugarcane — tropical and subtropical; hot and humid, 21°C to 27°C, rainfall 75–100 cm; needs manual labour. India is the second largest producer after Brazil; source of sugar, gur, khandsari and molasses.

    Oil seeds — about 12 per cent of total cropped area. In 2020 India was the second largest producer of groundnut after China. Groundnut is kharif and makes up about half of major oilseeds; Gujarat was the largest producer in 2019–20, followed by Rajasthan and Tamil Nadu. Linseed and mustard are rabi; sesamum is kharif in the north and rabi in the south; castor is both.

    Tea — plantation crop introduced by the British; tropical/sub-tropical climate, deep fertile well-drained soil rich in humus, warm moist frost-free climate, frequent evenly distributed showers; labour-intensive; processed within the garden. States: Assam, Darjeeling and Jalpaiguri (West Bengal), Tamil Nadu, Kerala. In 2020 India was the second largest producer after China.

    Coffee — the Arabica variety, initially brought from Yemen; first introduced on the Baba Budan Hills; today confined to the Nilgiri in Karnataka, Kerala and Tamil Nadu.

    Horticulture — in 2020 India was the second largest producer of fruits and vegetables after China. Mangoes (Maharashtra, Andhra Pradesh, Telangana, UP, West Bengal), oranges (Nagpur, Cherrapunjee), bananas (Kerala, Mizoram, Maharashtra, Tamil Nadu), lichi and guava (UP, Bihar), pineapples (Meghalaya), grapes (Andhra Pradesh, Telangana, Maharashtra), apples, pears, apricots and walnuts (Jammu and Kashmir, Himachal Pradesh).

    Rubber — equatorial crop; rainfall above 200 cm, temperature above 25°C; Kerala, Tamil Nadu, Karnataka, Andaman and Nicobar Islands, Garo hills of Meghalaya.

    Fibre crops — cotton, jute, hemp and natural silk. Rearing silkworms is sericulture.

  • Cotton — India is believed to be its original home; second largest producer after China; drier parts of black cotton soil of the Deccan; high temperature, light rainfall or irrigation, 210 frost-free days, bright sunshine; kharif, 6 to 8 months to mature.
  • Jute — the golden fibre; well-drained fertile flood-plain soils renewed every year; high temperature; West Bengal, Bihar, Assam, Odisha, Meghalaya; used for gunny bags, mats, ropes, yarn and carpets.

    • Technological and institutional reforms

  • Agriculture provides livelihood for more than 60 per cent of the population.
  • After Independence: collectivisation, consolidation of holdings, cooperation and abolition of zamindari; land reform was the main focus of the First Five Year Plan.
  • 1960s–70s: the Green Revolution (package technology) and the White Revolution (Operation Flood).
  • 1980s–90s: comprehensive land development — crop insurance against drought, flood, cyclone, fire and disease; Grameen banks, cooperative societies and banks for low-interest loans.
  • Other schemes: Kisan Credit Card (KCC), Personal Accident Insurance Scheme (PAIS), weather bulletins on radio and TV, and minimum support price, remunerative and procurement prices.

    • Bhoodan–Gramdan: at Pochampally (Telangana), when landless villagers asked Vinoba Bhave for land, Shri Ram Chandra Reddy offered 80 acres to 80 landless villagers — Bhoodan. Zamindars who gave whole villages made Gramdan. The movement is also called the Blood-less Revolution.

    Board Exam Focus

  • MCQs from the book: single crop on a large area — plantation agriculture; a rabi crop — gram; a leguminous crop — pulses.
  • 3-mark: one beverage crop and its conditions (tea); one staple crop and its regions (rice); institutional reforms for farmers.
  • 5-mark: government initiatives to increase agricultural production; geographical conditions for rice.
  • Model outline for rice: kharif crop → above 25°C → high humidity → rainfall above 100 cm → irrigation in low-rainfall areas → regions.

    Kisan Credit Cards, crop insurance and minimum support prices are still key debates in Indian agriculture, and millets are being promoted again for their nutritional value.

    Common Mistakes

  • Writing that all pulses fix nitrogen — the book says all except arhar.
  • Confusing seasons: gram and mustard are rabi; cotton, jute and groundnut are kharif.
  • Mixing up "second largest producer" rankings: rice, groundnut, tea, cotton, fruits and vegetables — after China; sugarcane — after Brazil; pulses — India is the largest.
  • Writing coffee is grown on the Baba Budan Hills today — it was introduced there; today it is confined to the Nilgiri in Karnataka, Kerala and Tamil Nadu.

    • 💡 Key Learning Points

    • ✓Distinguish primitive subsistence, intensive subsistence and commercial (including plantation) farming, with regional names for slash-and-burn.
    • ✓Identify rabi, kharif and zaid seasons with their sowing/harvesting months and crops.
    • ✓State the temperature, rainfall, soil and main states for major crops: rice, wheat, millets, maize, pulses, sugarcane, oilseeds, tea, coffee, rubber, cotton and jute.
    • ✓Recall India's rank as a producer of key crops as stated in the chapter.
    • ✓Explain the technological and institutional reforms in agriculture and the Bhoodan–Gramdan movement.

    👨‍🏫 Teaching Tips

    • →Start with the question in the text: name industries based on agricultural raw material, and list the students' answers.
    • →Build a crop fact chart (season, temperature, rainfall, soil, states) as a class, one crop per group.
    • →Use a calendar strip to show when rabi, kharif and zaid crops are sown and harvested.
    • →Read the Rinjha story and ask students to identify the type of farming and crops grown.
    • →Mark wheat-producing areas on an outline map as the chapter's project work.
    • →Discuss the Bhoodan–Gramdan story and why it is called the 'Blood-less Revolution'.
    • →Have students explore the Farmers' Portal mentioned in the chapter and report one useful piece of information.
