We often hear that India is an agricultural country. This basically means that agriculture is an important part of our livelihood. In India, agriculture is our primary economic activity and about two-thirds of our population is engaged in the same. Let us get acquainted with types of farming done in India.

Agriculture
The word agriculture is derived from a Latin word- ager or agri meaning soil, and ‘culture’ meaning cultivation of the soil. In modern terms, agriculture comprises “the art and science of cultivating the soil, growing crops and rearing livestock.”
You can consider farming to be rather a complete system which includes inputs, processing, and outputs. The inputs here are seeds, fertilizers, machinery, which then, undergoes operations like ploughing, sowing, irrigation, weeding, and harvesting. And thus, we get the final outputs like crops, dairy and poultry products.
Subsistence Farming
Subsistence Farming– This is farming which is done for consumption of the farm owners, can be either Primitive or Intensive. Here the only aim is to fulfil the needs of the farmer and his family.
Primitive subsistence farming is the type of subsistence farming that is typically done on small areas of land with traditional tools like hoe, dao, digging sticks etc. This is rather the most natural method of growing crops, because, the natural environment like heat, rain, wind and condition of the soil contribute to the growth of crops. Primitive farming further includes:
Shifting cultivation: In this primitive method, farmers clear the cultivated land, after harvesting the crops and burn the land. As a result, they maintain the fertility of the soil, so whoever uses the land next can get a good yield. This method is known by different names in different regions of India. Shifting cultivation is also practised in some countries in South America and South East Asia
Nomadic herding: This kind of farming method involves herders and farmers travelling from place to place with their flocks of animals. And, the herders also source wool, meat, hide and dairy products from the livestock. Nomadic herding is very common in Rajasthan, Jammu & Kashmir with herders rearing sheep, goats, yaks, and camel.
Intensive subsistence farming is quite in contrast to primitive farming, farmers practice intensive farming on wider areas of land, use modern machinery and tools and add chemical fertilizers for better crops.
