Abstract

Water is the prime requirement for the existence of life. Due to the limited water resources in Iran, it is essential to save and economize the use of water resources. This can be achieved by applying proper water manegment including storage and maintaining soil water, improving soil water permeability and increasing water use efficiency. The objective of this study was to investigate the effect of different rates of a superabsorbent polymer on dry matter yield (Y) and water use efficiency (WUE) of FORAGE COM. A greenhouse experiment was carried out as a factorial complete randomized design with 18 treatments and 3 replicates. Six levels of the superabsorbent (0, 0.05, 0.1, 0.2, 0.3 and 0.4 dry basis percentage, Soto S5) and three soils differing in texture (clay, loamy and loamy sand, A1 to A3) were used. FORAGE COM was planted in the pots. The pots were irrigated based on 60% depletion of soil available water for the all treatments. Yield (Y), evapotranspiration (ET) and water use efficiency (WUE) were measured.The rcsults indicated that the effects of soil, superabsorbent and their interactions were significant (P<1%) on Y and WUE. Clay soil (A1) had maximum Y and WUE and loamy soil (A2) and loamy sand soil (A3) had minimum Y and WUE. There were significant differences in WUE between S1 and the other rates.The S5 and S0 had maximum and minimum Y and WUE values, respectively. The results indicated that there was no significant difference between S4 and S5 treatments. Moreover, application of superabsorbent with five levels, increased Y and WUE. In summory overall, application of 0.05, 0.1 and 0.3 dry basis percentage of superabsorbent, in clay, loamy and loamy sand soils, caused maximum Y and WUE respectively. Finally, with increaseing superabsorbent, the Y increased, which in turn increased the WUE.
