This experiment was carried out split plot in randomized complete blocks design with three replications at north of Iran, Boushehr province in Ahram region in 2013. Irrigation region in three levels including (30, 50 and 70% discharge of available moisture content) as main plots and five humidity superabsorbent including (0, 0.25, 0.5, 0.75 and 1% by weight) as sub plots. Results showed that the most final yield was obtained in 30% discharge of available moisture content. Water productivity in 70% discharge of available moisture content because of decrease water use and water requirement of plant had been highest. The maximum final yield was produced at 1% by weight superabsorbent. As, final water productivity because of decrease water use and water requirement had observed with 1% superabsorbent application. The most fruit number per plant was obtained at interaction of 30% discharge of available moisture content and 0.75% superabsorbent application and interaction of 50% discharge of available moisture content and 0.25% superabsorbent application. The highest water productivity was observed at interaction of 70% discharge of available moisture content and 1% superabsorbent application. Therefore, superabsorbent application because of decrease water use in plant causes to increase yield and water productivity.
