A two years experiment was conducted to investigation of Cotton Irrigation timing by sprinkler system method at Hashem-Abad Cotton Research Station, Gorgan, North of Iran. For this aim, in 2004 and 2005 four Irrigation timing (M1=6-9 Am., M2=6Am.-13Pm, A=14-20Pm., N=21Pm.-5 Am.) with three replication based on 70% of class A pan evaporation were studied. In 2004, the irrigation timing had no significant effect on the quantity and quality traits of Si-Okra. The N and A treatment have had the highest and lowest total yield, respectively. The same results were taken in 2005. There was no difference in mean comparison between treatments, but in terms of quantity, the total yield of M1 and N were more than the other treatments. Finally, the night sprinkler Irrigation is prior to the others. In this region, as mater of fact, cotton is Irrigated 3-5 times, therefore, the sprinkler methods are recommended for cotton Irrigation despite of the increase of flower shedding because of cotton plant produce many flowers.
