In water scarcity conditions for fodder production, selection of suitable corn hybrids along with irrigation management is very important to improve water productivity. Accordingly, the present study was conducted as a split strip plot experiment in a randomized complete block design with three replications in the experimental field of Ahvaz Research Station in the 2018-2019 crop year. The main factor was irrigation interval at three levels of two, three and four days and the secondary factor was corn hybrids 704, 611 and Mobin.The results showed that the four-day cycle caused a 32.4% and 38.7% decrease in shoot and ear yield compared to the two- and three-day cycles, respectively. Comparing the mean interaction of irrigation cycle and hybrid treatments, it was found that the highest water productivity of 1.27 kg/m3 was obtained in hybrid 704 with a three-day cycle. In examining the effect of irrigation levels, due to the improvement of water productivity in the three-day cycle by 15% and 63%, respectively, compared to the two- and four-day cycles, this irrigation cycle is recommended. Also, the 704 and Mobin hybrids with a higher ear yield of approximately 16% compared to the single-cross 611 are recommended and promoted. Soil salinity monitoring showed that two and three-day irrigation periods reduced salinity in all soil profiles by an average of 46% and 37% compared to before planting. However, in the four-day period, although the salinity in the surface soil layer decreased by 27%, due to the accumulation of salts in the lower soil layers, the salinity increased by 15% in the 25-50 cm layer and 20% for the 50-75 cm layer. The results of this study indicate that to combat salt accumulation, intermittent leaching is required during the season and the removal of salts from the soil by underground drains.
