Subsistence farming is a type of farming in which the agricultural produce is not sold but is kept for the consumption by the family and to provide seeds for the next crop. It is a form of farming in which nearly all of the crops or livestock raised are used to maintain the farmer and the farmers family, leaving little, if any, surplus for sale or trade. Subsistence farming can be classified into two types: primitive subsistence farming and intensive subsistence farming. Primitive subsistence farming is a type of subsistence farming in which farmers use primitive tools and techniques to cultivate crops for their own consumption. Intensive subsistence farming is a type of subsistence farming in which farmers use advanced techniques and tools to cultivate crops for their own consumption.

Subsistence farming is usually practiced in developing countries where farmers have small landholdings and limited resources. The farms are usually small, consisting of no more than a few acres, and farm technology tends to be primitive and of low yield. The crops grown in subsistence farming are generally produced for consumption by the family, and heavy machinery is generally not used in this kind of farming.

Examples of crops grown in subsistence farming include rice, wheat, maize, millet, and sorghum. In India, rice is a common crop grown through subsistence farming. In Africa, cassava, yams, and plantains are commonly grown through subsistence farming.
