Abstract
India is a significant importer of edible oils and an important producer of oilseed. India stands as fourth leading oilseeds producing countries after USA, China and Brazil. Oilseed has become one of the most valuable agricultural commodities. Sulphur (S) plays an important role in determining the quality of oil seed from these crops. It is referred to as the fourth major nutrient after N, P and K because crops need sulphur slightly less than they require P. It is required for the formation of proteins, vitamins and chlorophyll. It is an integral part of amino acid such as cystine, cysteine and methionine which are essential components of protein. Plant can absorb sulphur in the form of sulphate (SO4 2-) which is decomposes into sulphur. It is a factor for the determination of higher yield seed and quality of seed that content oil in oilseed crops. Since, sulphur is immobile in plants, it must be continuously supplied from crop emergence till maturity. So, reduced yield can come sulphur shortage at any stage of growth. It can be overcome by supplying sulphur containing fertilizers to plant by soil application and foliar application. Among the source of sulphur, elemental sulphur and gypsum are widely utilized in sulphur deficiency.
