Abstract :Irrigation water is vital and most limiting input in arid agriculture. This study evaluates the late sown wheat crop under various agro-management practices for enhancing the crop productivity in water scarce area. Results exhibited that better leaf water relations expressed in terms of an improvement in the leaf water potential, leaf osmotic potential, stomatal conductance and relative water content of flag leaf as well as higher rates of transpiration and net COassimilation were recorded with the planting technique of seed spreading augmented with furrows. This planting technique also expressed higher number of productive tillers, 1000grain weight and grain yield whereas lower soil penetration resistance as compared to other planting treatments. The highest water use efficiency insert ignore into journalissuearticles values(WUE); was achieved with the irrigation regime of 80% insert ignore into journalissuearticles values(evapotranspiration); ETo while in case of planting techniques, seed spreading augmented with furrows expressed the maximum values of WUE. The highest grain yield was recorded with flat sowing subjected to the irrigation equivalent to 100% reference evapotranspiration insert ignore into journalissuearticles values(100% ETo); which was almost similar with seed spreading augmented with furrows at 80% ETo. Under deficit irrigation regimes insert ignore into journalissuearticles values(80 and 60% ETo);, seed spreading augmented with furrows performed better than the other two planting techniques
