Efficient Techniques to increase Water Use Efficiency under Rainfed Eco-systems

Water is the prime mover in agricultural development in rainfed agriculture. For better use of water in agriculture in water-limited environments, efforts are needed from different research disciplines; agronomists, plant breeders, plant physiologists, plant biotechnologists, water engineers and others, to develop new approaches in water use. Among different approaches water productivity or water use efficiency (WUE) is an efficient approach.Water use efficiency can be increased by two ways, either by increasing yield or by saving water. Water use efficiency is affected by a number of factors like climatic conditions, edaphic factors, nature of plant and agronomic practices. There are various techniques to increase water use efficiency in the rainfed ecosystem. Many options to improve water use efficiency are available and the target is to produce more biomass with minimum possible amount of water.
