The quality of irrigation water is assessed in the main water sources of Peja-Istog area, Kosovo. Thirty-two water samples were collected in the sampling points during the peak dry season (2015). Sixteen of these samples were collected in July, whereas the rest were collected in August from the same sampling points. The content of the samples have been analyzed. The classification used to assess the suitability of irrigation water for various qualities are FAO and USSL classification criteria. An additional evaluation for the suitability of irrigation water was also used including assessment of sodium adsorption ratio (SAR), sodium percentage (SSP), residual sodium bi-carbonate (RSBC), magnesium content (MAR), permeability index (PI), and Kelly’s ratio (KR). The results of physicchemical analyses and calculated parameters of water quality suggest that all water samples are suitable for irrigation purposes. Therefore, the surface water of this area is of an excellent quality and is highly recommended for irrigation purposes
