Effects of using Aquasorb Polymer on irrigation of Pinus eldarica, Olea europea and Atriplex canescens.

This experiment was carried out in 2001 in order to determine the effect of aquasorb polymer on irrigation of three plant species in Hossein Abad Station of Sand Stabilization of Qom province. The Factorial statistical method under Randomized compete blocks design whit three replicates was used. There were two Factors: species (Atriplex canescens, Pinus eldarica Medw. and Olea europea L.) and Aquasorb polymer (0.0%, 2.0%, 4.0% with irrigation interval three times were than normal interval) and control irrigation with normal interval). The variables were: Soil water content (%) before and after irrigation (at depths of 25 and 50 cm) and survival % one, three and six months after plating. The ANOVA and Duncan tests were used to analyze the data. The results showed that there were significant differences (p<0.01) in respect to survival% between the planted species. The species Atriplex canescens p., Olea europea and Pinus eldarica obtained the greatest survival percentage, respectively. The effects of Aquasorb polymer treatments on the measured variables (except soil water content ratio of after irrigation to before irrigation at 50 cm depth) were significant (p<0.01). There was a not significant differences between the levels 2.0 and 4.0% of Aquasorb polymer on one hand and between these levels and control irrigation regime on another hand. It is suggested to apply Aquasorb at level of 2.0 instead of normal irrigation for planting three species at similar climate and soil conditions as the studied site.
