Abstract: 
Water for paddy fields irrigation is getting scarcer in Guilan. water input can be reduce by reducing ponded water depths to another water managements. The research was conducted a RCB design with 4 treatments and 3 replications at rice research Institute of Iran, Rasht in one rice variety consisted of Hashemi. The results over this and another research of Hashemi variety showed, water saving was on average 40% with yields reductions of only 10%. Water Productivity and Water Use Efficiency were 0.28-0.75 and 0.29-0.92 Kg grain per water. Total rice production can be increased by using water saved in one location to irrigation new paddy field in another. If this is not done, a strategy of saving water at the field level potentially threatens total rice production at large.
