Agriculture in India-Food Crops Types of Agriculture in India Agriculture plays an important role in the Indian economy in the following ways: a. It provides food for the ever increasing population of the country. b. It supplies raw materials for agro-based industries such as the textiles and food processing industries. c. It provides a market for industrial goods such as machinery and agricultural implements. d. It provides employment to millions of people. e. It accounts for a large portion of India’s exports. Some types of agricultural farming in India are shifting agriculture, subsistence agriculture, intensive agriculture, extensive farming, plantation farming and mixed farming. Shifting Agriculture  It is also known as ‘Slash and Burn Agriculture’ and ‘jhum’, ‘ponam’ or ‘podu’. It is a primitive method of cultivation. In this type of cultivation, a patch of forested land is cleared by felling and burning trees. The ashes of trees are mixed in the soil.  After two to three years, when the soil loses its fertility, the land is left fallow, and a new patch of land is cleared for cultivation.  Maize, potato, yam and cassava are grown in shifting cultivation. It is mainly practised in northeast India.  Dry paddy, maize, millets and vegetables are commonly grown in this type of farming. This method of cultivation has some disadvantages. It results in deforestation, accelerates soil erosion and causes floods and silting. Subsistence Farming  A majority of farmers in India practise subsistence farming. Land holdings in this type of farming are small, and farmers use traditional methods of agriculture.  As farmers are poor, they do not use fertilisers and high-yielding seed varieties in their fields.  The production is not very high. Food crops are mainly produced for consumption by the family. Intensive Farming  This kind of cultivation is practised in areas with high density of population.  It is a labour intensive system whereby fertilisers, high-yielding seed varieties and irrigation methods are used for increasing production.  More than one crop is cultivated on the same field. Extensive Farming  This kind of cultivation is practised where the size of the agricultural field is large and productivity is high.  Machines are extensively used, and hence, the labour employed per unit area is low.  Farmers specialise in the production of one or two major commercial crops.  Rice, wheat, maize and sugarcane are the main crops which are grown in extensive farming. Because the productivity is high, there is large surplus for sale. Plantation Farming  In plantation farming, single crops of tea, sugarcane, coffee, rubber, cotton and banana are grown on large fields.  Large labour force and capital are required in plantations.  Developed transport is required to transport these crops to factories for processing.  Latest technology and modern methods of agriculture are used. In this kind of cultivation, crops are mainly exported to earn foreign exchange. Mixed Farming  In mixed farming, two or more crops are grown together on a rotational basis.  Apart from growing crops and fodder crops, animals are also reared.  This type of cultivation ensures farmers with a steady income. Commercial Farming  In this type of farming, crops are grown for commercial purposes, i.e. for selling in local and international markets.  Wheat and maize are the main crops which are grown in commercial grain farming.  Farming is mechanised and is prevalent in areas where farms are large and the market is strong.  In India, this kind of farming is practised in Punjab, Haryana, Gujarat, Western Uttar Pradesh and Andhra Pradesh. Dry Farming  It is practised in areas where irrigation facilities are not readily available. Crops which can stand dry weather such as jowar, bajra and ragi are mainly grown.  The fields are repeatedly ploughed before and during rains to preserve soil moisture.  This type of cultivation is practised in Western Rajasthan and in some parts of Deccan. Problems Faced by Indian Agriculture Environmental Factors  Unreliable rainfall  Lack of irrigation facilities  Soil erosion  Reduction in net sown area Institutional Factors  Small and fragmented land holdings  Exploitation of farmers Economic Factors  Subsistence agriculture  Challenges posed by globalisation Technological Factors  Use of old and inefficient techniques by Indian farmers Steps Taken to Improve Agricultural Production in India  Introduction of various reforms such as the abolition of the Zamindari Act.  Consolidation of fragmented land holdings  Creation of irrigation infrastructure  Announcement of minimum support prices  Provision of subsidies to farmers for purchasing fertilisers and seeds Green Revolution Green Revolution is a term which is used to describe manifold increase in farm production in India. Its main features are  Use of large-scale capital and technological inputs  Use of high-yielding seed varieties  Use of chemical fertilisers and extensive irrigation facilities  Adoption of modern scientific methods of farming Impact of the Green Revolution  Owing to large production, the Green Revolution changed Indian agriculture from subsistence farming to commercial and market-oriented farming.  Creation of more employment opportunities.  Farmers were benefited by increased productivity leading to rural prosperity.  It made India self-sufficient in food grains. However, the Green Revolution was criticised by environmental scientists because of land degradation caused by overuse of fertilisers and decease in soil fertility due to over irrigation. Agricultural Crops and Seasons There are two major agricultural crops in India—rabi crops and kharif crops. In India, there are three main types of cropping seasons. They are rabi, kharif and zaid. Types of Sowing Period Harvesting Period Main Crops or Seasonal Conditions Cropping Fruits Seasons Rabi Winter (October– Summer (April–June) Wheat, barley, Rainfall during winter December) peas, gram and months in northern India mustard because of western temperate cyclones helps in the growth of crops. Kharif Beginning of the September–October Rice, maize, jowar, Much needed moisture is monsoon (July) groundnut, tur and provided by the monsoon cotton rains in India. Zaid March–April May–June Watermelon, These crops are grown cucumber, between the rabi and vegetables and kharif seasons. These fodder crops require warm weather to grow. However, it is to be noticed that this categorisation of the cropping season does not exist in southern India. Rice It is the most important staple food crop of India. It is a kharif crop which is grown extensively in the northern plains, northeastern parts of the country, and coastal and deltaic regions. Rice requires high temperature above 20°C–35°C and high rainfall between 150 cm and 300 cm. During the earlier phase of its growth, the crop requires 5–10 cm of standing water. India is the second largest producer of rice in the world after China. The rice crop in India can be divided into upland and lowland rice. Upland Rice Lowland Rice It is mainly grown on mountainous regions. It is mainly grown on low-lying regions. It is sown in March–April and harvested in It is sown in June and harvested in October. September–October. The crop is mainly used for local consumption. The crop is not only consumed locally but is also sold to other regions. Soil: Rice requires fertile, clayey and loamy soil for cultivation. It grows well on alluvial soil which should be able to retain standing water in the field. Manure and fertilisers are added to increase production. Methods of Cultivation Rice in India is cultivated by two methods—the dry method and the puddle method. The dry system of cultivation is mainly confined to regions which depend on rainfall and do not have sufficient irrigation facilities. In this method, seeds are scattered by hand in areas of moderate rainfall and are sown in rows with the help of drills in areas of heavy rainfall. Puddle or wet method of cultivation is practised in regions which have adequate supply of water. After ploughing, land is filled with 3–5 cm of water. The cultivation of rice is carried out by the following steps:  Sowing of seeds  Transplanting  Harvesting  Processing Sowing of Seeds Seeds are sown by various methods. These are Broadcasting Method: In this method, seeds are scattered all over the field. This method is prevalent in regions where labour is scarce and the soil is infertile. Drilling Method: In this method, seeds are sown in furrows with the help of a drill usually made of bamboo. The germination of seeds is high as seeds fall into furrows systematically. This is however a time-consuming way to sow seeds. Dibbling Method: In this method, seeds are sown at regular intervals in furrows. Transplanting Method  In this method, seedlings from nurseries are transplanted into rice fields in groups of four to six at a distance of 30–45 cm.  Initially, the field is covered with 2–3 cm of water. The level of water is then increased to 4–6 cm till the crop matures.  This method is popular as it gives higher yield. Japanese Method  In this method, the seedlings are prepared in nurseries.  The rows of plants are then fixed at a distance of 25 cm, and the distance between the plants is about 15 cm.  Manure is used extensively to increase yield. Plants give higher yield by this method. Harvesting and Processing  The rice fields are drained dry just before the crop is harvested. Each stalk is then hand reaped.  The moisture content of the stalk is reduced by drying stalks in the Sun.  In threshing, grains are separated from the stalks. It is done in the field to reduce the cost of transport.  During winnowing, unwanted husk is removed from the grains by pouring them from a height.  Milling is then done to remove yellowish husk from the grains. Distribution India produces 22% of the total rice in the world. It is mainly grown in West Bengal, Uttar Pradesh, Haryana, Andhra Pradesh, Punjab, Bihar, Assam, Maharashtra, Gujarat, Meghalaya, Manipur, Tripura and Tamil Nadu. Wheat It is the second most important crop in the country after rice. It is a rabi crop. India accounts for 12% of the total wheat production in the world. Climatic Conditions: Wheat requires a cool climate. It requires a temperature of 10–15°C during sowing and 20–25°C during harvesting. About 80 cm of rainfall is ideal for wheat cultivation. Soil: Well-drained loamy soil is suitable for the growth of wheat. Wheat is a rabi crop which is sown Methods of Cultivation during winters and harvested during summers.  Seeds are generally sown by the drilling and broadcasting methods.  The wheat crop starts ripening in March and is harvested in April when the temperature is 27.5°C. Distribution  Uttar Pradesh, Haryana, Rajasthan and Madhya Pradesh are five leading producers of wheat in the country. Wheat yield is extremely high in Punjab and Haryana.  The yield of wheat is low in Madhya Pradesh, Himachal Pradesh and Jammu and Kashmir as it is grown under rain-fed conditions. Millets Climate required for the growth of millets Name of Temperature Rainfall Required Soil Distribution the Crop Required Jowar 27–32°C It grows in arid and Red, grey and Maharashtra, Madhya semi-arid regions yellow loamy soils.

Ragi 20–30°C It is grown in Red and sandy Karnataka (leading regions receiving loamy soil and well- producer), Tamil Nadu, 50–100 cm of drained alluvial soil. Uttarakhand, rainfall. Maharashtra and Andhra Pradesh Pulses  Pulses are an important part of the Indian diet as they provide vegetable protein. Some pulses are gram or arhar, urad, masur (lentil), moong (black gram) and matar (peas).  Temperature ranging between 20°C and 25°C and rainfall between 50 cm and 75 cm are required for growing pulses.  Pulses grow well in dry light soil.  Gram is the leading pulse and is sometimes grown along with wheat. While gram is raised as a rabi crop in regions receiving about 10 cm of rainfall, urad and moong are raised as kharif crops.  Pulses are leguminous crops which increase the content of nitrogen in the soil, increasing its fertility.  India is the largest producer and consumer of pulses in the world. Madhya Pradesh, Maharashtra, Uttar Pradesh, Rajasthan and Andhra Pradesh are the five leading states producing pulses.
