Effects of Irrigation Regims and N Levels Fertilizers on Quantity and Quality of Grain Corn This search is conducted to determined on effects of irrigation regims and N levels Fertilizers on yield and quality of Grain Corn. This project is conducted with 3 moisture regimes: T1= 40% reduction available water , T2= 60% reduction available water, T3= 80% reduction available water and 3 levels of N- fertilizer N1= 130, N2=180, N3= 230 kg/ha with 9 treatments in 3 replications. Results showed that effects of moisture regimes is very significant on yield of corn, total yield, 1000 weight grain and length of corn (1%). Using of T2 N2 treatment yield of corn was 13200 kg/ha. This treatment has 219 mm net irrigation and 180 kg/ha N. Using of T2 N2 total yield of corn was 29330 kg/ha. Key words: Irrigation Regims , N Fertilizers, Yield, Quantity, Quality, Corn
