Abstract The interaction effects of different applied ratios a hydrophilic polymer (Superab A200) (0, 0.2, 0.6% w/w) under various soil salinity levels (initial salinity, 4 and 8 ms/cm) were evaluated on available water content (AWC), biomass, use efficiency for corn grown in loamy sand sandy clay loam soils. results showed that the highest AWC was measured at lowest salinity. application w/w level increased by 2.2 1.2 times greater than those control soils, respectively. analysis variance data effect significant biomass amounts these traits soils with level. Application rate 0.2% resulted aerial root corn. At rates 2.6 1.7 Thus, especially increases holding capacity, yield, plant. On other hand, decreases negative plant helps irrigation projects to succeed arid semi‐arid areas.
