The Role of Improving Water Use Efficiency in Irrigated Agriculture for Enhancing the Production and Productivity of the Crops

Water scarcity and the increasing global demand for water in many sectors, including agriculture, has become a global concern .The rapid growth world population and the adverse impacts of climate change lade to growing computation for water use by industrial and urban users for agriculture to secure enough food. Irrigated agriculture is an important role in total agriculture and provides humanity with wide range of agricultural products, including fruits, vegetables, grains and cereals. Effective management of water use is the only way to save water for the increasing irrigated agriculture. Different approaches have been adopted to reduce the damage caused by drought; among these approaches is water productivity or water use efficiency WUE. A crop with high WUE should have greater yield than crop with low WUE.
