Abstract

Fresh water resources are decreasing globally, because of climate change and increasing competition of industrial and urban development. Scarcity of water resources in world’s leading rice-producing countries such as China and India has threatened the production of rice crop, which is the main staple food in Asia, particularly China, India, Indonesia, Bangladesh, Vietnam and Pakistan. Hence increasing demand of rice needs more attention towards this crop production globally. On the other hand it is an aquatic crop; needs more water as compared to wheat, maize etc. Therefore it is imperative to investigate the ways to get good yield with minimum input of water. In this context an effort has been made to review the water saving techniques for the enhancement of rice production in paddy field with minimum input of water.

Key words: Water saving techniques, yield, growth of rice crop.
