Food is any substance consumed to provide nutritional support for the body. It is usually of plant or animal origin, and contains essential nutrients, such as carbohydrates, fats, proteins, vitamins, or minerals. The substance is ingested by an organism and assimilated by the organism’s cells in an effort to produce energy, maintain life, or stimulate growth. Historically, people secured food through two methods: hunting and gathering, and agriculture. Today, most of the food energy consumed by the world population is supplied by the food industry. With increasing concern over both the methods and products of modern industrial agriculture, there has been a growing trend towards sustainable agricultural practices. Agriculture is the oldest profession and applied science in the world. Revolutionary changes have taken place in the field of agriculture. Most of the developing countries are grappling with the plans of the development of agriculture. This hand book covers all the aspects of agricultural sciences. It is hoped, the book will be found to be of immense value to the students of higher education.
