Under conditions of water scarcity, using treated municipal wastewater for irrigation of agricultural crops is necessary. At the present time, several wastewater plants are being built in different cities of Iran. In this research, to assess the effects of wastewater usage on wheat, an experiment was performed near Shahinshahr Wastewater Treatment Plant and Rowshan wheat variety was grown during 2000-2002. For this purpose, four irrigation treatments were applied in a complete random block design, as: Irrigation with well water based on ET-HS model (T1), irrigation with treated wastewater based on ET-HS model (T2), irrigation with treated wastewater based on 10% more than ET-HS model (T3), irrigation with treated wastewater based on 20% more than ET-HS model (T4). The results showed that the treated-wastewater quality parameters such as salinity and SAR were better than well water. Irrigation with treated wastewater, as compared to well water, resulted in higher yields. No significant difference (p<0.05) was observed between T2, T3 and T4, but T2 had the highest water use efficiency. Application of wastewater didn’t cause any increase in concentration of specific ions and heavy metals over the standard levels in different parts of wheat.
