3 Subsistence agriculture Self-sufficiency farming in which the farmers focus on growing enough food to feed themselves and their families. The typical subsistence farm has a range of crops and animals needed by the family to feed and clothe themselves during the year. Planting decisions are made principally with an eye toward what the family will need during the coming year, and secondarily toward market prices.

In commercial farming crops such as wheat, maize, tea, coffee, sugarcane, cashew, rubber, banana, cotton are harvested and sold into world markets. Commercial agriculture includes livestock production and livestock grazing. Due to the expensive nature of capital formation and implementation of technological processes, the landowners of such farms are often large agricultural corporations (especially in developing countries).
