Types of Farming
- The cultivation methods depend upon the characteristics of the physical environment, technological know-how and socio-cultural practices.
- Farming varies from subsistence to commercial type.
- In different parts of India, the following farming systems are practised.
Primitive Subsistence Farming
It is a ‘slash and burn’ agriculture. Farmers clear a patch of land and produce cereals and other food crops.
When the soil fertility decreases, the farmers shift and clear a fresh patch of land for cultivation.
It is known by different names in different parts of the country. It is known as jhumming in northeastern states.
- Land productivity is low in this type of agriculture.
- This type of farming depends on monsoon.
- This farming is practised in few parts of India.
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 higher production.
- This type of farming uses higher doses of modern inputs such as high yielding variety (HYV) seeds, chemical fertilisers, insecticides and pesticides to obtain higher productivity.
- Plantation is a type of commercial farming in which a single crop is grown on a large area.
- Plantations cover large tracts of land, using capital intensive inputs, with the help of migrant labourers.
- All the produce is used as a raw material in industries. Eg: Tea, Coffee, Rubber, Sugarcane, Banana.
