This book is intended for students of agriculture studying in different institutions in India. It would also be useful for scientists, extension workers to help to understand the fundamentals of agronomy to enhance productivity for livelihood security of farmers. It is equally urgent to agricultural scientists dealing with crops, regional planners and extension workers. Thus, an attempt has been made to provide such a perspective to all stakeholders, students, scientists and planners. Basic knowledge of Indian agriculture is being described even today as a gamble of the monsoon and every year farmers' fate oscillate with the behaviour of the monsoon. In these circumstances, a new design of Agronomy is required. Keeping in view these things this book has been written, which will be helpful for researchers, teachers and students of agricultural institutes/universities. All readers are welcomed for valuable criticism and suggestions to make this book more useful. Table of Contents..
