Abstract: In order to determine water requirement and Irrigation Interval of wheat (Mahdavi) in Golpayegan an experiment was conducted by four treatments (50, 75, 100 and 125 mm evaporation of class A pan) using a complete Randomized block design with four replicates. before Conducting the experiment physico chemical characteristics of soil samples were determined. Before each irrigation, water content of soil from 0-15, 15-30 and 30- 60 cm were measured. Since then irrigation treatments were used. The results showed that effect of different Irrigation treatments on grain and straw of wheat was significant. The yield of 75 mm evaporation treatment was 7825 kg/ha grain and 13625 kg/ha straw and was more than other treatments. The yield of 50, 100 , 125 mm irrigation treatments was less than of 75 mm respectively. The effect of different Irrigation treatments on protein and thousand grains weight was not significant. The content of water consume of 50, 75, 100 and 125 mm treatments were 11261, 10238, 9282 and 8696 m3 /ha respectively during growth period of wheat. (water efficiency was %65). The treatment based on 75 mm evaporation was beat irrigation interval for wheat in Golpaygan.
