Abstract :

Iran has a warm and dry climate and its annual rainfall is 250 millimeter.Therefore,in Iran with the low rainfalland its very unsuitable distribution, the effective use of modern technology to improve the use of water resources efficiency in limited water resources is vital.One of these solutions to protect and store moisture is the use of super absorbent and soil reformer.In this research,the effect three levels of zeolite(0,10and15weight percent)and four levels of superabsorbent geohumus(0,100,150,250gr) and irrigation(normal irrigation,low irrigation)on the vegetative properties of Nitraria schoberi in seedling cultivation on the field, as well as the effect of these materials on some properties of soil were investigated. In order to evaluate the effect of each factors including irrigation, type and level of superabsorbent addition on the studied characteristics, the data were analysis using SPSS-22 software and the data were analyzed according to the analysis of variance table and the mean comparison of the treatments was doneby Duncan's comparison test. The results showed that the use of superabsorbent in this study had a significant positive effect on growth indices of seedlings includingheight, large diameter, small diameter and collar diameter of Nitraria schoberi seedlings in comparison with control sample.The highest amount of vegetative indices by normal irrigation was respectively(60.22cm,67.33cm,13.88cm,6mm)andThe lowest amount was associated to, low irrigation treatment (control).In addition, the use of superabsorbent had a positive effect on some properties of the soil. In other words, the addition of the superabsorbent to the soil reduced the Electrical Conductivity(1/39dS/m), reducing the Bulk Density(1/46g/cm³)of the soil
