Abstract :
Background and Objective: A large part of the water used in big cities change as wastewater. Due to lack of water resources, municipal wastewater treatment plant's effluent can use as one of the important sources of new water in order to the development of green spaces, green belt in around cities and agriculture purposes. Material and Methodology: In this analytical-descriptive study, the degrees of compatibility of various crops with water used in irrigation were studied. For surveying a suitable pattern by wastewater treatment plant's effluent for irrigation agriculture, the quantity and physical and chemical properties of wastewater treatment plant's effluent in sabzevar city have been analyzed. Findings: The results showed that the quantity of wastewater treatment plant's effluent is daily 2000m3. Due to having hot and dry climate and included sand and light soil, crops such as barley, corn, millet, forage, cotton and alfalfa and discreet wheat are good. Discussion and Conclusion: to cropping of legumes and vegetables due to viral and parasitic pollution were avoided and the warm climate in the region which is an increase of salts in the soil surface is avoided. The best irrigation method is subsurface irrigation system. To expand the area under crops in the region was caused stabilizing soil and reduce the adverse effects from winds on the lives in sabzevar city.
