Agricultural Practices and Animal Husbandry
We all need food to survive. Food is the basic need for all living beings, as it provides energy for doing work, and raw material for building and repair of various parts of the body. You know that our country has a large population, and therefore, we need to produce a lot of food. You also know that to produce such a large amount of food we need a large area of land. However, our land availability is limited. Indian scientists have experimented and researched and suggested ways and means by which more food can be grown than before, on the same piece of land. Improved methods of agriculture have led to the production of about 360m tonnes of plant food products and about 88m tonnes of animal food products.
