Why is subsistence agriculture still practiced in certain parts of the country? Give four reasons.

Subsistence agriculture is still practiced in certain parts of the country due to the following reasons:
(i) Small piece of land: In some parts of the country, the farmers have only small patches of land where they do farming with the help of primitive tools like hoe, dao and digging sticks, and family labour.
(ii) Poverty: Small farmers are poor. They cannot use fertilisers and high yielding variety of seeds.
(iii) Lack of irrigation facilities: In some parts irrigation facilities are not available to the farmers. The farming still depends upon monsoon. In such situation they can produce only what they need.
(iv) Fertility of the soil: At places where the soil is not fertile, only subsistence agriculture can be practised. Thus the farmers are compelled to produce to sustain their family.
