It is estimated that in Africa and Asia, 85-90% of all the fresh water is used for agriculture and by 2025, agriculture is expected to increase its water requirements by 1.3 times (Shiklomanov, 1999). To meet the water requirements of the burgeoning population and for the industrial consumption, water has to be diverted leaving less water available for agriculture. When water becomes limited, naturally, the crop production gets hampered as there would be uncertainty in the availability of water at the critical stages of growth affecting the survival and yield prospects of the crops. Thus, there is a great need to explore the possibilities for saving available water for meeting the requirements of critical growth stages of the crop production. This article attempt to summarize the work carried out by various researchers on the physiological aspects of crop production under limited water supply. The lack of water at critical stages of plant growth is called drought stress, and researchers are working to screen the drought tolerant germplasm having the drought tolerant traits to be used in the breeding programs.
