In order to investigate the effect of superabsorbent and mycorrhizal fungi on reducing water consumption, growth traits and potato yield, an experiment with strip-factorial design was performed. In this study, the amount of irrigation water at three levels (100, 75 and 50% of water requirement based on evapotranspiration) in horizontal plots and the use of Trawat200A super absorbent with two levels (0 and 80 kg / ha) and mycorrhiza on two levels (inoculation and non-inoculation with Glomus etunicatum) were placed in vertical plots. The results of combined analysis of variance showed that effect of irrigation and the use of mycorrhiza and superabsorbent were significant in most vegetative traits as well as yield. Means comparison showed that vegetative traits and total yield decreased by application of low irrigation, but this decrease was significantly less in mycorrhizal inoculation conditions and with the application of superabsorbent polymer. Under moderate and severe stress conditions, the combined use of mycorrhiza and superabsorbent increased the total yield compared to non-consumption (control) by about 9.5% and 10.15%, respectively.
