  In order to investigate irrigation management and the effects of different amounts of nitrogen fertilizer on hybrid corn SC704 experimental in the form of crushed plots in the form of complete randomized block design in three replications during two crop years 2015 and 2016 in Golestan province, in Katul was done. The main factor of irrigation cycle by day in four levels including 7, 14, 21 and 28 days and the secondary factor of nitrogen fertilizer in four levels included 60, 120, 180 and 240 kg.ha-1. The results of analysis of variance showed a significant effect between irrigation cycle and nitrogen on Weigh of 1000 grains, grain yield, seed nitrogen and biomass yield. The results showed that 28 days of irrigation reduced grain yield, seed nitrogen, seed phosphate and seed potassium compared to 7 to 14 days of irrigation. The increase in nitrogen fertilizer to 180 and 240 kg.ha-1 increased the yield of the grain by affecting the biological yield and yield components seed nitrogen, seed phosphate and seed potassium. However, nitrogen consumption in higher amounts under stress conditions (21 to 28 day Interval Irrigation) not only did not have a positive effect on yield, but also reduced grain yield by 180 to 240 kg.ha-1. The highest grain yield was obtained in the combination of 7 and 14 day irrigation treatment and nitrogen level of 240 to 180 kg.ha-1 and 12209, 11416, 10147 kg.ha-1. The results of the average comparison between the two years showed that the highest number of grains per corn was 583, the Number of grains per row as 40.3 and the Weigh of 1000 grains was 138.9 grams and seed nitrogen 3.991 µg.g-1 DW in the second year.
