Improvement in Food Resources

India is a very populous country. The efforts have been made to meet the food demand by increasing food production. The varieties of crops are selected by breeding method for various useful characteristics such as disease resistance, response to fertilisers, product quality and high yields. The nutrients play an important role in the growth and development of crops. There are thirteen nutrients essential for crops. Some nutrients are required in large quantities and are known as macronutrients and some nutrients are required in small quantities and are known as micronutrients. Manure contains large quantities of organic matter while the fertilisers are commercially produced artificial nutrients. In mixed cropping two or more crops are grown simultaneously on the same piece of land. The method of growing two or more crops in definite row patterns is known as inter-cropping. The process growing of different crops in pre-planned succession is called crop rotation. Animal husbandry is an agricultural practice of breeding and raising livestock. Animal husbandry includes cattle, sheep, goat, poultry, bee and fish farming. Indian cattle belong to two different species namely: Bos indicus (cows) and Bos bubalis (buffaloes). Poultry farming is the raising of domesticated birds such as chickens and ducks for the purpose of meat and eggs. Pisciculture can be done by two methods: capturing and culturing. Apiculture is the maintenance of a honey bee colony for the production of honey.
