Agronomy is a compulsory subject for the undergraduate and post-graduate students of Agriculture in Colleges and Universities of India and abroad. The crop production and post harvest technology have gradually being changed due to coming up of some inputs of Agriculture such as high yielding varieties of different crops, pesticides, fertilizers etc. to fulfil our goal of crop production, it is essential to have some sound knowledge on different aspects of Agronomy. Keeping this fact in view in the present book, attempts has been made to provide readily available informations on various aspects of Agronomy. The remarkable contents of the book are climatology, growth and development of crops, soil, cultivation, manures and fertilizers, water management of crops, weed and weed control, agroforestry. We do hope that this book serves as an advanced text and reference book for students, research scholars, teachers and those who are actively engaged in different fields of Agriculture. This book contains 9 chapters, a positive approach to mobilize the farmers in right direction.
