An investigation was carried out to study the quality of irrigation water in pomegranate growing areas of Hosadurga taluk in central dry zone of Karnataka. Water samples were collected from the bore wells of different age groups (< 2 years and > 2 years) of pomegranate gardens and were analyzed for various parameters. The analysis of the samples revealed that the pH of irrigation water was Alkaline in nature with mean of 8.65. Electrical conductivity was (mean) of 0.67 dS m-1. Calcium and Magnesium concentrations were mean values of 4.7 and 2.1 meq l-1 respectively. The mean Na and K concentration in irrigation water were 0.57 and 0.12 meql-1respectively. The mean carbonate and bicarbonate content in irrigation water was 1.42 and 4.35 meql-1. The residual sodium carbonate content (RSC) ranged from -0.2 to -3.1 meql-1 with mean of -1.03. The sodium adsorption ratio (SAR) ranged from 0.08 to 0.96 meql-1 with a mean value of 0.30 meq l-1. Nitrate and sulphate concentration in irrigation water ranged from 0.08 to 1.15 and 1.3 to 4.2 with mean values of 0.66 and 0.22 ppm respectively. The irrigation water was slightly alkaline in nature and all other quality parameters are placed within the safer zone.
