Abstract
The quality of irrigation water determines the soil health. The good quality irrigation water ensures the better yield of crops. A study was conducted all over Gujrat District, Pakistan to interpret the quality of irrigation water. In this study the random sampling for water samples was carried out throughout three tehsils of district Gujrat including Gujrat, Kharian and Sara-i-Alamgir for a period of five years. The irrigation water quality was assessed on three parameters i.e., EC (uS/cm), RSC (meq/L) and SAR (Sodium adsorption ratio). About 2020 water samples from Tehsil Gujrat, 259 from Tehsil Kharian, and 12 from Tehsil Sara-i-Alamgir were collected. The highest values of EC (522-1645), SAR (0.00-14.97) and RSC (0.00-9.4) was noted in Tehsil Gujrat which is the biggest Tehsil of Gujrat District. The study revealed higher fitness in EC as compared to RSC and SAR. The overall fitness in District Gujrat, fit water samples were 78.27 %, marginally fit water samples were 5.45%, and unfit water samples were 16.23%. It was also concluded that 91% water samples were unfit due to EC. Hence, it may be recommended where the quality parameters are poor, the water needs reclamation for better crop yield.
