Application of proper management and using advanced techniques in order to conserve soil moisture and increase soil moisture holding capacity are among the most effective procedures for increasing water use efficiency and consequently for improving utilization of the nation water resources. Limitations in the availability of good quality water resources, forcing the researchers to find out efficient and economic methods to increase water use efficiency. Due to climate conditions of Iran which is arid and semi-arid, and also due to excessive use of water in agricultural sector, one of the proper techniques and one of the solution for the above problem is to use soil amendments such as superabsorbent polymers. The use of superabsorbent polymers improve soil physical conditions and absorb the scatter rain and other water resources which the results is less soil water tension for arid and semi-arid rejoins. In order to investigate the effect of deficit irrigation and Aquazorb superabsorbent on yield of Pinto beans ( Phaseolus vulgaris ) a field study was conducted in 2013 at the city of Dehaghan in Isfahan Province. The study was conducted in split-plot design and the main treatments were different amounts of irrigation water including irrigation water levels of 60, 80, 100 and 120% of the soil moisture deficit and the sub-treatments were different amounts of Aquazorb superabsorbent including S 0 as control treatment (zero kilograms per hectare), S 100 (100 kilograms per hectare), S 200 (200 kilograms per hectare) and S 300 (300 kilograms per hectare). After land preparation, the experimental plots were obtained and the Aquazorb superabsorbent was mixed with soil up to 10 cm depth and the plots were irrigated to make the Aquazorb superabsorbent stabilized in the soil and then the bean was planted. The characteristics including length of the main stem, dry weight of vegetative parts without bean seed, one hundred grain weight, harvest index and bean seed yield (kilograms per hectare) were analyzed using SAS statistical software and the LSD test was used for mean comparison of data. The results of the analysis of variance showed that as the superabsorbent increases the length of the main stem, dry weight of vegetative parts without bean seed, one hundred grain weight and bean seed yield increases. The highest increased was belonged to treatment of 300 kilograms per hectare of superabsorbent. Also, as the irrigation water increased the length of the main stem, dry weight of vegetative parts without bean seed, one hundred grain weight and bean seed yield increased. The highest increased was belonged to irrigation treatment of 120%. For harvest index, there were no significant differences between superabsorbent treatment of 100 kilograms per hectare and treatment of without superabsorbent. The highest harvest index with value of 39.8% was belonged to irrigation treatment of 80% and superabsorbent treatment of 300 kilograms per hectare. In general, the irrigation treatment of 80% is recommended for the area that farmers are facing either with lack of irrigation water or high value of irrigation water.
