With respect to water shortage during the recent decades, subsurface irrigation method has been considered in arid and semiarid zones. Therefore, experimental design was performed as completely randomized blocks with four repetitions in Isfahan University of Technology. Then, the effects of different irrigation intervals of every day, every other day and once a week under the surface and subsurface irrigation on height, collar diameter, chlorophyll content and stomata conductivity of Zygophyllum fabago L. were investigated. The percentage of plant survival was also recorded six months after planting. The results showed that irrigation interval had a significant effect on height, chlorophyll content and stomata conductivity of the tested plant (P<0.05) and the height, diameter of the collar and stomata conductivity decreased by increasing the irrigation interval. While, the irrigation interval didn’t have a significant effect on the collar diameter (P>0.05). The highest percentage of survival (100%) was observed in subsurface irrigation treatment and control treatment had the lowest percentage of viability (70%). It could be concluded that the improvement of growth parameters and survived of Zygophyllum fabago were better with the subsurface irrigation than the surface irrigation.
