Abstract :

More than two thirds of Iran is located in arid and semiarid regions encountered with the challenges of water shortages. This emphasizes the need to reduce water consumption and to use other water sources. For this the present study deals with effect of sewage and wastewater on some vegetative traits of Nitraria schuberi as a species adapted to arid and semiarid areas. Its design was a split plot design with six replications in desert Research Station, plain Segzy Isfahan. This study had irrigation with wastewater treatment at five levels ( 0 , 25 , 50 , 75 and 100 % ) , sludge at two levels ( presence or absence of sludge ) and two soil types ( soil and soil Segzy plain ) and analyzes morphological characteristics of the plant using a software SPSS software was used. Results showed that the highest rate of increase in height and canopy, basal diameter and canopy in prairie soil treatment sludge 100 percent and non- sludge effluent level for height, basal area and canopy diameter was 100, 50 and75% respectively. Also, results showed that the lowest height, basal diameter and canopy cover for Segzy soil under control treatment for height, basal diameter and canopy cover was 0, 25 and 25% respectively. Also, as for soils under sewage treatment for height, basal diameter and canopy cover were 0, 25 and 50% respectively and for wastewater application treatment it was 75,0 and 0% respectively.
