Optimum use of consuming water in agriculture sector is one of the most major and effective solutions to cope with water crisis. Therefore, deficit irrigation is stated as a proper solution in water limitation aiming to maximally use water volume unit. Application of saving soil moisture techniques together with irrigation management increase the irrigation efficiency and promote sustainable agriculture. We considered that usage of super absorbent polymers contribute to optimal use and preservation of water resources. Our study was conducted during two growth seasons within 2014-2015 in the farm and in Sari University of Agricultural Sciences and Natural Resources on single cross 704 silage maize. The treatments included three irrigation regimes (as the main plot) and three levels of super absorbent (as subplots) with three replications. Irrigation treatments consisted of complete and partial root irrigation in two levels of 55 and 65% (PRD65, PRD55) and three levels of water super absorbent polymer of A200 type, including 0, 30 and 60 kg/ha. The plants, that were regularly irrigated during their growth period and cultivated with 60kg/ha of super absorbent, had the highest yield but they were not significantly different from plants, irrigated with 55 and 65% water volume. Thus, super absorbent reduced the irrigation volume and made possible to generate the same yield with water use 35 and 45 % lower.
