The concentration of dissolved constituents in water determines its quality for irrigation use. Quality of irrigation water is an important consideration in an irrigated area. In the present study irrigation water quality of Madanapalle town was analysed by selecting eight different villages and from each village 3 water samples were collected and analysed for primary parameters such as pH, Electrical conductivity, alkalinity, total hardness, potassium, chloride and sodium in order to understand the irrigation water quality index. The secondary water parameters such as sodium adsorption ratio, soluble sodium percentage, Kelly’s ratio, residual sodium carbonate and Permeability index were calculated from the data obtained from primary parameters. The results stated that the pH of the samples ranges from 6.21-8.34 and EC is ranging between 0.50-4.32 dSm-1. Sodium and potassium content of water ranges from 1.39-4.78 and 0-0.51 MeqL-1 respectively. Whereas calcium and magnesium (calcium + magnesium) ranges from 4.8-58.4 MeqL-1. Chloride and bicarbonate content ranged from 2.4-30 and 1.4-4MeqL-1. Accordingly irrigation water quality index was found that 8.33% of the samples were found sustainable, 62.50% of the samples were found slightly sustainable and 25.00% of the samples found unsustainable. The results strongly recommend that still improvement has to be done to improve the quality of irrigation water mainly by improving the cultivation practices.
