Agriculture is the main enterprise for more than 70 per cent of Indian population. With diverse climatic conditions, all most all crops are grown extensively throughout India. Green and yellow revolution has changed the status of Indian Agriculture from begging bowl to one of the exporter. But to feed growing population (1.8 per cent) and to enhance crop productivity we have to achieve an annual growth rate of 4.5 per cent, inspite of declining use of inputs and rapidly deteriorating natural resources. Hi-tech agriculture is the only way to meet out these challenges.

Growth in Agriculture in terms of increased sustainable productivity has to come from location specific, low input, eco-friendly and demand oriented techniques. Lot of research work has been carried out in different projects in different parts of India, but there is lack of up-to-date and compiled information to be useful for under graduate and postgraduate students, research workers and for progressive farmers.

This publication has been brought out with an objective of collecting information regarding location specific research and recommended technologies for harvesting high productivity on sustainable basis. To make this publication more informative and relevant, chapters on different crops have been invited from scientist working in the field or have a vast experience. Efforts have been made to present each chapter in an useful way and readable manner for quick understanding.
