The quality of water intended for irrigation is mainly determined by the content and type of salts present in it. The purpose of this research is to evaluate Yamanigüey River’s water quality for agricultural irrigation in 12 samples taken throughout the basin in preliminarily way. Performance of physicochemical parameters was evaluated and water quality was determined based on the values of sodium adsorption ratio, electrical conductivity, irrigation coefficient, potential salinity and effective salinity. It is concluded that waters on Yamanigüey River have a good to excellent quality and, according to Riverside standards, its water is suitable to use in agricultural irrigation, except in very low permeability soils for salinity and sodium sensitive crops.
