The quality of irrigation water directly influences the quality of soil and the crops grown in the soil. Quality of water used for agricultural purposes is directly proportional to the yield. The present study was conducted to find the quality of Gungua Badiya river water and its usability for agricultural purposes in Abaya district, West Gujji Zone, Oromiya Region, Ethiopia. To analyze the physicochemical parameters of the river water, nine samples were collected from upper, middle and lower parts of the river. The physicochemical parameters are analyzed to explore the usability of the river water are: pH, Electrical conductivity (EC), Total dissolved solids (TDS), Calcium (Ca2+), Magnisium (Mg2+), Sodium ( Na+), Chloride (Cl- ) and Residual Sodium Carbonate (RSC), Sodium adsorption ratio (SAR) and Soluble Sodium Percent (SSP). After evaluating the parameters, it is found that the river water is usable to agricultural purposes and meet the standards directed by UCCC, WHO and FAO.
