Agricultural water use efficiency to adapt climate change in Indo-Gangetic plains of south-east Asia

Enhancing crop water productivity by genetic improvements or agronomic manipulations and reducing evapotranspiration losses from soil plant surface is the need of hour. Selection breeding traits which lead to increase in like early maturing stress tolerant cultivars with deep thick root system, hairy leaves partitioning assimilates towards grains etc. can help increasing productivity. Different management options like, alteration planting time, more efficient methods, tillage practices, irrigation management, intercropping, use anti-transpirants, row orientation, geometry application mulches shelter belts play important role for sustainability resources However, best option varies according location, prevailing weather conditions as well social economic farmers.
