Irrigation water is one of the most critical resource for agricultural production. Under ICAR-All India Coordinated Research Project functioning at Anbil Dharmalingam Agricultural College and Research Institute, Tiruchirappalli, water samples were collected from Tiruchirappalli and other adjacent districts for ground water characterization. Of these water samples collected, high SAR saline waters are found in Udiyur block of Kankeyam area, Erode district. A laboratory study was conducted to study the effect of high SAR saline water on germination per cent and biomass yield in cotton plants. Different sources of water and amendments were used. Maximum biomass yield and high germination per cent were recorded when best available water was used as a source of irrigation followed by gypsum treated water. The germination per cent was 90.0 and 82.5 respectively. Among the amendments, soil application of vermin compost (5 t ha -1) and press mud (t ha -1) registered higher germination per cent.
