Abstract: Sustainable crop production should be managed to enhance soil ecosystems, improving soil health and fertility and reversing degradation and pollution of land. As well as, it should be contributed to maintaining and improving, and efficiently utilizing, water resources (quantity, access, stability and quality), especially promoting practices that minimize risks of water pollution from agrochemicals and save water. In present study, the effect of land leveling, cut off irrigation and N- fertilizer on yield and yield components of wheat have been studied. The results showed that the highest yield of grain and straw of wheat was obtained with using Nfertilization rate 288 kg N ha-1, land levelling rate 0.01 % of surface slope and cut off stream of irrigation rate 75%. The best investment factor (2.64) was also achieved using the previous treatment. The results of this study suggest that, irrigation application efficiency (%) increased from 66 % (for control) to 75.4 % for cut off 75 % of stream irrigation and land leveling with 0.01 % slope. Thus, about 30.8 % from the applied water for irrigation is saved by the previous treatment.
