Introduction

Primitive human lived on wild plants and animals. They started facing starvation due to increase in food demand with the increase in number. The domestication of botanical plants and their cultivation marks the dawn of civilization. Modern crop production is the application of the principles of physical, biological and social sciences for growing of domesticated plants to meet the diversity of human needs in a profitable manner. It is a continuous challenge to increase the crop yields to remain ahead of human population increase. The dynamic process of crop production is now facing the challenge of global climatic change. New potent crop varieties and technologies must be explored for the survival of ever increasing people on limited resource base under various climatic conditions. The continuous concern in crop production is to use optimally the resources necessary for crop production in a sustainable manner. The sustainable use of resources implies current utilization in an optimum way saving their productivity for the use of future generations.
