Eight varieties/hybrids of tomato were tested at Dilipnagar Research Farm, Kanpur at 38.0, 26.0, 14.0 and 11.6 ESP levels during 2000–01 and 36.5, 25.3, 13.5 and 11.2 ESP levels during 2001–02. These ESP levels were obtained by adding different doses of gypsum, i.e. @100% GR, 66% GR and 33% GR in alkali soil. In control, gypsum was not applied. Salt tolerant variety Angoorlata produced significantly higher fruit yield and characterized by lower Na/K ratio, than other varieties/hybrids of tomato that were tested.
