Chemistry, JNKVV, Jabalpur (M.P) during Rabi season of 2013-14 and 2014-15 under AICRP on MSN in a Factorial randomized block design with three replications and ten treatments comprising viz., T1 (Control), T2 (15 Kg S ha -1 ), T3 (30 Kg S ha -1 ), T4 (45 Kg S ha -1 ), T5 (60 Kg S ha -1 ), T6 (FYM 5 t ha -1 ), T7 (15 Kg S ha -1 + FYM 5 t ha - 1 ), T8 (30 Kg S ha -1 + FYM 5 tha -1 ), T9 (45 Kg S ha -1 + FYM 5 t ha -1 ) and T10 (60 Kg S ha -1 + FYM 5t ha -1 ).The results obtained from the present investigation clearly indicated that yield of seed and straw increased significantly with enhancing sulphur up to highest level of 60 kg ha -1 + FYM 5 t ha -1 .S X FYM interaction showed significant difference in seed protein content. Treatment combination of Sulphur 60 kg ha -1 + FYM 5 t ha -1 recorded maximum percentage of protein (18.85%) and oil (41.29%) content in seed. However, better improvements in yields were exhibited when S and FYM were integrated together. This increase might be due to steady decomposition of FYM and release of nutrients throughout the crop growth period coupled with better assimilation of nutrients. Highest seed (1684.70 kg ha -1 ) and Stover (4739.82 kg ha -1 ) yields was recorded with the application of Sulphur 60 kg ha -1 + FYM 5 t ha -1 over rest of the treatments. Keywords: Mustard, Sulphur, FYM, Yield, Quality Introduction Mustard is the third most important oilseed crop after groundnut and soybean in India. In Indian agricultural economy, oilseeds are important next to cereals in terms of area, production and value with accounting for about 1.5% of gross domestic production and 8% of value of all agricultural products (Hegde, 2009) [13] . Sulphur is best known for its role in the synthesis of proteins with the formation of amino acids methionine (21% S) and cysteine (27% S), chlorophyll, oil content of the seeds and nutritive quality of forages (Jamal et al., 2005) [16] . Integrated use of sulphur and farmyard manure improves the availability of sulphur in soils and plays a significant role in improving quality and seed development (Ghosh et al., 2002) [12] . Sulphur uptake and assimilation in rapeseed-mustard are crucial for determining yield, oil, quality and resistance to various stresses. Among the oilseed crops, rapeseed-mustard has the highest requirement of sulphur. Sulphur increases the yield of mustard by 12 to 48% under irrigated and 17 to 24% under rain-fed condition (Aulakh and Pasricha, 1988) [2] . More sulphur is therefore, required need for their oil and protein synthesis in oilseed crops. Sulphur nutrition in oilseeds indicated a considerable increase in yield and quality of oilseeds (chauhan et al., 2002) [6] . Sulphur deficiency in crops is gradually becoming widespread in different soils of the country due to use of high analysis sulphur-free fertilizers coupled with intensive cropping, higher crop yields and higher sulphur removals. Because of its involvement in vital function in the plant metabolism, sulphur deficiency would lead to adverse effect on growth and yield of many crops. However, organic manures, particularly FYM are important components of integrated nutrient management (Patra et al., 1998) [27] not only supply macronutrients but also meet the requirement of micronutrients, besides improving soil health. Keeping this in view, the present investigation was planned to studies on the effect of sulphur with and without FYM on yield and quality of mustard crop in Vertisols. Material and Methods The field experiment was conducted on Research Farm of the Department of Soil Science and Agricultural Chemistry, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur (MP) during
