What is Agriculture?
- Agriculture is the process of producing food for people, fodder for cattle, fiber and many other desired products by the cultivation of certain plants and the raising of domesticated animals (livestock).
- India is an agriculturally important country.
- Two-thirds of its population is engaged in agricultural activities.
- It is a primary activity.
Types of Farming:
Primitive Subsistence Farming:
- It is also called as Shifting Cultivation or Jhumming or Slash and Burn Cultivation.
- It is practised on small patches of land with the primitive tools like hoe, dao and digging sticks, and family/community labour.
- This type of farming depends upon monsoon, natural fertility of the soil and suitability of other environmental conditions to the crops grown.
- In shifting cultivation, a plot of land is cleared by felling the trees and burning them. The ashes are then mixed with the soil and crops like maize, yam, potatoes and cassava are grown. After the soil loses its fertility, the land is abandoned and the cultivator moves to a new plot.
- It is called as jhumming in north-eastern states like Assam, Meghalaya, Mizoram and Nagaland; Pamlou in Manipur, Dipa in Bastar district of Chhattishgarh, and in Andaman and Nicobar Islands.

Intensive Subsistence Farming:
- This type of farming is practised in areas of high population pressure on land.
- It is labour-intensive farming, where high doses of biochemical inputs and irrigation are used for obtaining higher production.
- Intensive subsistence farming is prevalent in the thickly populated areas of the monsoon regions of south, southeast and east Asia.
- Main characteristic of this type of farming is the use of higher doses of modern inputs.
- Example– high yielding variety (HYV) seeds, chemical fertilizers, insecticides and pesticides in order to obtain higher productivity.
- The degree of commercialisation of agriculture varies from one region to another.
- For example- rice is a commercial crop in Harayana and Punjab, but in Orissa, it is a subsistence crop.
- Plantation is also a type of commercial farming.
- In this type of farming, a single crop is grown on a large area.
- Plantations cover large tracts of land, using capital intensive inputs.
- In India, tea (Assam and North Bengal), coffee (Karnatka), rubber, sugarcane, banana etc. are important plantation crops.
- Dryland agriculture is associated with agriculture in absence of irrigation facilities. Thus this type of agriculture is wholly dependent upon rain. This type of agriculture is significance from Indian point of view because more that 75% of the cultivable land fall under rainfed area. A not so well developed canal system and sinking ground water further makes it significant.
It is divided into 3 types –
- Dry Farming – Moisture/Precipitation is less than 750 mm annually.
- Dryland Faming – Mositure is more than 750 but less than 1000 mm.
- Rainfed Farming – Cultivation of crops in regions receiving more than 1,150 mm.
- Crops that are grown in such areas are – Pulses, Winter Wheat, Mllets like – Bajra.
- Dryland farming depends upon the moisture-holding capacity of the soil and many measures are taken to promote this – like mulching, clearing of weeds, contour ploughing, etc.
- However, dryland farming is also more prone to erosion especially wind and water. In rainy areas, this is more acute such as Maharashtra and Punjab wherein peak rainy season erosion is more.
Methods of Dry Farming:
- The field is ploughed repeatedly in order to conserve moisture in the soil. This process is necessary especially during the raining season so that rainwater is properly utilized.
- Soil fertility is reduced when cultivation is continued for a number of years. This problem becomes serious particularly in the background of farmer’s inability to make use of fertilizers and manures. In order to solve this problem, the land is left as fallow land. It helps in the recuperation of soil fertility.
- The Pulverisation of soil is done before sowing. This process converts soil into small particles that permit the easy flow of water in the soil and plant roots find ample opportunity to grow in strength and support the plants.
- Hoeing, weeding, and pruning are done at regular intervals. Hoeing allows air to enter the soil space and helps in plant growth. It is generally done before sun-rise so that night dew can enter the soil and provide moisture to plants. Through weeding, unwanted plants in the fields are removed and pressure on the soil to feed the plants is reduced. Pruning removes unwanted parts of the plants and wanted plants to find ample opportunity to grow.
- The land is usually covered with straw to reduce evaporation of the soil moisture and to control soil erosion by wind.
- In order to improve their income level, the farmers keep themselves engaged in allied agricultural activities such as livestock keeping and dairying.
Problems of Dry Zone Agriculture:
- Rainfall is scarce, erratic, unreliable, and uncertain which makes this region susceptible to floods, droughts, and famines.
- Large areas are covered by sandy soil which lacks nutrient materials for soil fertility.
- The area is prone to soil erosion, particularly erosion by wind.
- Yields are low and crops are susceptible to pests and diseases.
- Due to a lack of moisture and inadequate irrigation facilities, it is difficult to use HYV seeds and new technologies.
- The majority of the farmers are poor and cannot afford costly inputs like better seeds, fertilizers, farm mechanics, etc.
- Large areas of dry farming lack basic infrastructural facilities like market, transport, storage, refrigeration, etc. The farmers are forced to opt for distress sales in the absence of these facilities and fail to get remunerative prices for their products.
India has three cropping seasons- rabi, kharif and zaid.
- Are sown in winter from October to December and harvested in summer from April to June.
- Some of the important rabi crops are wheat, barley, peas, gram and mustard.
- Also called as monsoon crops.
- Are grown with the onset of monsoon in different parts of the country and these are harvested in September-October.
- Important crops grown during this season are paddy, maize, jowar, bajra, tur (arhar), urad, cotton, jute, groundnut and soyabean.
- In states like Assam, West Bengal and Orissa, three crops of paddy are grown in a year. These are Aus, Aman and Boro.
- In between the rabi and the kharif seasons, there is a short season during the summer months known as the Zaid season.
- Some of the crops produced during ‘zaid’ are watermelon, muskmelon, cucumber, vegetables and fodder crops.
- Sugarcane takes almost a year to grow.

- Mahatma Gandhi declared Vinoba Bhave as his spiritual heir.
- The Bhoodan-Gramdan movement was started by Acharya Vinoba Bhave is also known as the Blood-less Revolution.
- In order to ensure the availability of food to all sections of society, our government carefully designed a national food security system. It consists of two components- a buffer stock and the public distribution system (PDS).
- PDS is a programme which provides food grains and other essential commodities at subsidized prices in rural and urban areas.
- India’s food security policy has a primary objective to ensure the availability of foodgrains to the common people at an affordable price.
- The focus of the policy is on growth in agriculture production and on fixing the support price for procurement of wheat and rice, to maintain their stocks.
- Food Corporation of India (FCI) is responsible for procuring and stocking foodgrains, whereas distribution is ensured by the public distribution system (PDS).
- The FCI procures food grains from the farmers at the government announced minimum support price (MSP).
- The government used to provide subsidies on agricultural inputs such as fertilizers, power, and water.
- Excessive and imprudent use of fertilizers and water has led to waterlogging.
- Organic farming is much in vogue today because it is practiced without factory-made chemicals such as fertilizers and pesticides.
- The crops which are cultivated for commercial purpose are called cash crops. These crops include sugarcane, tobacco, fibre crops (cotton, jute, and mesta) and oilseeds.
