Date palm offshoot needs adequate water for establishment and growth in primary years after planting. Therefore irrigation scheduling is very necessary for increasing the establishment and growth of date palm offshoots. An experiment was conducted to study on amounts of superabsorbent polymer applying on surviving of date palm offshoot at date palm and tropical fruit research institute of Iran, during 2011-2012. The experiment was laid out under Randomized Complete Block Design (RCBD) with split plot arrangement, having three replications in which irrigation rate were kept in main plot and super absorb were in sub plot. Experiment comprised a following treatment combination irrigation based on %60, %80 and %100 class A pan in main plots, superabsorb in four rates (0, 40, 80 and 120 g for each offshoot) in subplot. The water requirement was calculated based on FAO pan method. The offshoot growth characteristics such as establishment percent, plant height, number of leaves, leaf length and width, number of leaflets, leaflet length and width, truck diameter and for any treatment were determined. The results showed that irrigation treatments or superabsorb had no significant effect on establishment of date palm offshoot and another vegetative characteristics. There was significant effect between leaflet length and trunk perimeter in the interaction of irrigation and super absorb treatments. The most suitable treatment was irrigation based on % 60 evaporation and 80 g superabsorb.
