Application of ammonium sulphate, superphosphate and muriate of potash mixture, containing sufficiently higher sulphur component increased the availability of heat soluble and available soil sulphur fractions of soil and leaf sulphur content. Heat soluble sulphure, a reliable index for assessing sulphur availability was found to be well above the critical limits of 15 to 20 ppm proposed by several workers. Leaf sulphur status was well above the critical values of 200 ppm that was considered to represent adquate supply.
