Improving Water Use Efficiency through Reduced Irrigation for Sustainable Cotton Production

The socio-economic development of a country is highly dependent on water availability. Nowadays, increasing scarcity major global challenge. Continuing improvements in water-use efficiency are essential for cotton production sustainability. Reduced irrigation could be solution to shortage the arid climate without compromising yield. Therefore, two-year field study was conducted assess effect two levels i.e., 50% and 100% available content (AWC) yield four genotypes (CIM-678, CIM-343, CRIS-613, CYTO-510). maximum seed observed CIM-678, which 2.31 2.46 Mg ha−1 under AWC during 2018 2019, respectively, non-significantly reduced by 7.7 8.94%, owing deficit irrigation. use (WUE) 0.55 0.64 Kg mm−1 significantly higher than WUE at both years. Leaf area index physiological parameters such as photosynthesis rate, transpiration stomatal conductance were not affected So, it concluded that technique performed well significant loss, improve WUE, saved 37 cm used other crops or increase crop.
