Investigating the effects of soil and sewage sludge on some vegetative traits of Garadagh plant (Nitraria schoberi)

More than two thirds of Iran is located in arid and semi-arid regions facing water shortages challenges. This emphasizes the need to reduce water consumption and the use of other unconventional water resources. Based on this fact, the present study deals with the 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, Segzy plain, Isfahan. In this study, 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 (agronomical soil and Segzy plain soil) were used and morphological characteristic analyses of the plant using a SPSS software was done. Results showed that the highest rate of increase in height and canopy, basal diameter and canopy in Segzy plain soil is in 100% sludge and non- sludge treatments, whereas the same increase is for agronomical soil in sludge treatment with 100% Sludge and non- sludge treatments for plant height of wastewater level of 50%, basal diameter level of 100% and canopy cover of 75%. level for height, basal area and canopy diameter was 100, 50 and75%, respectively. The results showed that the lowest height, basal diameter and canopy cover for Segzy soil under non-sludge treatment for height, basal diameter and canopy cover was 0, 25 and 25%. Also, as for soils under non-sludge treatment for height, basal diameter and canopy cover wastewater levels were 0, 25 and 50% respectively, and for sludge application treatment 75% for basal diameter and 0% height and canopy cover, respectively.
