This experiment was conducted in Karaj as split plot in a RCBD with 3 replications in 2017. The experimental treatments included irrigation management at three levels: irrigation with surface brush, sub surface (15 cm depth), and atmospheric and backyard in the main plot and irrigation management at three levels: 50, 100 and 150 mm evaporation from the pan in subplots and application of titanium dioxide nanoparticles in three levels: zero (control), 2 and 4 mg/lit in sub-sub plots. The results of this study indicated that divergence method (sub surface type) can be used to optimize the use of water resources to reduce irrigation losses and achieve high yield in corn production. Application of irrigation management of subsurface ribbon barrels along with titanium dioxide nanoparticles of four milligrams per liter in corn fields reduced 85% of weeds. Result showded that corn and weed competition reduced tissue texture and allocated photosynthetic sources to seed more than stems and corn leaves. Also, the use of titanium dioxide nanoparticles increased the activity of antioxidant enzymes and corn yields. The highest yield in this treatment was obtained at 10450 kg/ha.
