One hundred and thirty nine irrigation water samples collected from 65 chewing tobacco growing villages of Dindigul, Karur, Tirupur, Nagapattanam, Cuddalore and Erode districts of Tamil Nadu were analysed for pH, EC, calcium, magnesium, sodium, carbonates, bicarbonates and chlorides. From the data Residual Sodium Carbonate (RSC) and Sodium Adsorption Ratio (SAR) values were computed and water quality classes were determined. The main source of irrigation in the chewing tobacco growing districts of Tamil Nadu is open wells/ bore wells. Irrigation water samples are alkaline in Dindigul, Karur, Tirupur and Cuddalore districts. In Nagapattanam, 39% of water samples tested were neutral and 61% were alkaline. In Erode district 53% samples were neutral and remaining 47% were alkaline.
In Dindigul district, 19% samples for EC were in C2 category, 63% were in C3 category and 18% in C4 category. In Nagapatnam, Cuddalore and Erode district majority samples are in C3category. InKarur and Tirupur districts 100% waters samples were in C2 category. Chlorides in all the irrigation water samples irrespective of the district were high. In Dindigul district, SAR was low (
