The objective of the present investigation was to Study the quality parameters of irrigation water and its influence on soil chemical characteristics and temporal variation of water and soil properties from Junnar tahsil of Pune district. The water and soil samples were collected during month of June 2003, October 2003 and February, 2004 and analysed for their different chemical properties. Among the quality parameters of irrigation waters, pH of all water samples was found alkaline in nature. The electrical conductance showed, about 11.78 per cent samples were found good category and 70.58 per cent samples were found permissible and only 17.64 per cent samples were found doubtful category for crop production. Among the cations Na+ was predominant cation followed by Ca"^, Na+, K+ whereas in anionic concentration, it was observed that SO4" was predominant followed by CI" and HC03" and CO3" were in traces. As per the SAR and RSC ratings these irrigation water were found to be suitable for crop production. As per the temporal variation in irrigation water is concerned, pH showed highest value in October month whereas EC was highest in June and lowest in October. The trend of total cations and anions were as similar to EC. The temporal variations in pH and EC of soil showed no much variation. The cation concentration was highest in the month of June and was lowest in the month of October. In irrigated soils, pH of irrigation water showed significantly positive correlation with soil pH, Ca2+, Mg+2, and Na+ and trends were similar for EC of water also. The exchangeable Ca of irrigation water had positive influence on soil pH, EC, soil Ca2+, Mg+2, and Na+. The Mg2+ and Na+ also showed significant correlation with soil pH, EC, Ca2+, Mg+2. RSC showed significantly negative correlation with all soil chemical properties.
