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. OBJECTIVES After completing this lesson, you will be able to: • state reasons for human dependence on plants and animals for food; • define and differentiate between agriculture and horticulture; • list and explain the various steps for raising an improved crop; • differentiate between manures and fertilizers with the help of examples; • explain various agricultural practices adopted for improvement of food such as, crop rotation and multiple cropping; • state the need for protection of crops; • explain the terms and give examples of weedicides and insecticides; • suggest methods of storage of agricultural produce; • explain the meaning of green revolution; • state the need for animal husbandry; • cite examples of three groups of domesticated animals; • explain methods adopted for management of live stock for better production; • state common diseases of domestic animals and their prevention. 32.1 HUMAN DEPENDENCE ON PLANTS AND ANIMALS FOR FOOD Our food items are either plant products, such as grains, vegetables and fruits or animal products like milk, egg, mutton, chicken etc.
