Sodium potassium ratio as an index to sodicity tolerance of tomato
2006
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.
