In recent years due to water shortages and drought in Iran, the use of surface waters in this country is very important for agricultural use. Indicators in the field of assessing the quality of drinking water is provided, but the type and quality of irrigation water for agricultural products of particular importance given. Therefore, this study aims to provide solutions for measuring the quality of irrigation water is used. Here indicators NSFWQI, BCWQI, CWQI and OWQI corrected using Vilcox diagram and the FAO publication 286 for pressurized irrigation. Qualitative parameters of SAR, Na+, Cl-, and pH, HCO3-, Ec and TDS were measured on two stations Abharrud River, in the name of Kineh Varas and Qorveh of 2001 was up to 2010. Results showed that these indicators are acceptable in agriculture and about the same results presented Abhar Rud River. Kineh Varas station in assessing all indicators has less vulnerability than Qorveh station and it is also evident in the fact. The NSFWQI was the best index of irrigation water vulnerability. In order to determining of effective parameters on NSFWQI index, a sort of check list has been providing to irrigation and agriculture experts. Considering of their preference besides using AHP approach, weight of quality parameter has been determined.
