Abstract
Sulphur is a dynamic source to produce quality seed having higher marketable value. It is an important constituent of plant protein i.e. cysteine, cystine and methionine for the growth and development of quality seed. Real-time application of recommended dose of Sulphur fertilizer during the grain filling stage revealed higher crop yield with seed containing Sinigrin, Gluconapin, and progoitrin protein as indicator of greater quality seed. Adequate application of Sulphur facilitates the nitrogenous component to metabolites into nitrate easily which, promotes the chlorophyll present in the leaf, plant height, dry matter, leaf per plant, greater seed weight and mostly important the flavor in seed. However, the lack of knowledge about the importance of Sulphur fertilizers among the smallholder farmers in Nepal, productivity and marketable quality of the oil seed crop were decreasing. Weak communication of farmer among the knowledge provider and input suppliers revealing the crop into starving soil, remoting traditional acknowledge with better farming for greater yield. Without ensuring the quality of the crop, farmers were applying greater amount of chemical fertilizer for promising higher amount of crop yield. farmers were more oriented toward profit rather than quality.
Highlights
Oil seed crops are those crops which are grown for edible oil and oil derivatives
Decline in application of sulphur fertilizer has resulted in Sulphur deficiency in soil, leading to reduction crop yield and quality [7].This review is written by compiling different scientific literatures so that it can be a useful information for students, researchers and other agricultural enthusiasts who are working for increasing productivity and quality of oil seed crops in Nepal
Sulphur nutrition is a major constituent for the quality of oilseed crops. the reduced application of sulphur in oilseed crops has resulted in decreased seed quality
Summary
Oil seed crops are those crops which are grown for edible oil and oil derivatives. Commonly grown oilseed crop in Nepal are mustard, rapeseed, sesamum, linseed, soybean and sunflower. Farmers were cultivating rapeseed and mustard crop under energy starvation condition to cover the fallow land which has resulted in their continuous decreased productivity. The main reasons behind decreased yield and quality of oilseed crop like rapeseed are improper fertilization, micronutrient deficiencies, poor plant population and decreased seed yield of mustard in Terai region is due to lack of suitable cropping system [3]. Decline in application of sulphur fertilizer has resulted in Sulphur deficiency in soil, leading to reduction crop yield and quality [7].This review is written by compiling different scientific literatures so that it can be a useful information for students, researchers and other agricultural enthusiasts who are working for increasing productivity and quality of oil seed crops in Nepal
