Abstract: This study reviews management of saline irrigation water for enhancing crop productivity. Saline/ alkaline water has been successfully used to augment irrigation supplies and help to raise water productivity. Harnessing synergetic effects of improved salt-tolerant crops and varieties offer a possible approach to enhance productivity in these areas. Various approaches for improving and sustaining productivity in a saline environment include in situ conservation of rainwater in precisely leveled fields,and blending saline and fresh water to keep resultant salinity below threshold or to achieve its amelioration and precision irrigation technique with salty water at less salt-sensitive stages. Other productivity-improving measures involve soil and water management practices, methods of irrigation, its frequency and time of application or withholding of irrigation to maintain an environment favourable to crop production.
