Investigation of the Effect of Irrigation with Urban Wastewater on Growth Indices of Green Space Species in Tehran (Nerium Oleander and Festuca)

This research is based on a field study of the role and effluent performance on the growth and maintenance of urban green space in the form of a research by designing experiments and building blocks for two different species as a real pilot, The field of evaluation has provided the possibility of reusing the effluent of Ekbatan treatment plant In this study, with the aim of identifying sustainable water sources in order to maximize recycling and pathology of the potential of using wastewater in Tehran to implement the goals of human ecology of sustainable development, the effect of irrigation with treated effluent on vegetative characteristics (including height, number of branches, etc.) The plant species of fennel Nerium Oleander and Festuca have been studied. The growth and yield of selected plants were evaluated and compared under complete treatment of effluent and well water. For this purpose, this study was conducted in the open space in the form of a multi-observation completely randomized controlled trial (CRD) design with three replications. The results showed that the growth rate of different organs under the influence of treatment conditions is noticeable and observable growth. Nerium Oleander had the greatest effect on the height and diameter of the canopy cover from the effluent treatment, while the effect of the effluent treatment in Festuca, in addition to the height and canopy cover, was also on the leaf length. Therefore, it can be concluded that the use of treated wastewater to irrigation of urban green space is possible and leads to more favorable plants growth.
