Abstract : The irrigation water quality supplied to the irrigators has a remarkable effect on both crop quality and yields. This necessitates increasing research on the irrigation water quality. The study’s primary purpose was to evaluate the efficiency of Karur district (Tamil Nadu) of the Amaravathi River. Samples of groundwater were collected before and after the monsoon. Numerous water quality indices have been evaluated for the specific bore wells. The absorption ratio of sodium, (%SSP or %Na) the exchangeable percentage of sodium, (RSC or RA) the residual sodium carbonate, the permeability index, (CAI1, CAI2) the chloroalkaline indices, Kelly's ratio, potential salinity, the total solids dissolved, the magnesium hazard, the total hardness are some of these parameters. A large percentage of the cations were sodium (72.05%) and magnesium (19.48%). While chloride and bicarbonate accounted for 60.88 and 21.49 percent of total anions, calcium and potassium ions were of secondary importance, making about 6.75 and 1.72%, respectively. Sulfate ions accounted for 16.81% of the total ion concentration. However, the levels of bicarbonates, nitrates, and fluoride were extremely low. The analysis of several parameters specified the moderate appropriateness of groundwater for the purpose of irrigation.
