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). 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) 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). 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) . More sulphur is therefore, required need for their oil and protein synthesis in oilseed crops. Sulphur nutrition in oilseeds International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Special Issue-7 pp. 723-731 Journal homepage: http://www.ijcmas.com An experiment was conducted at the field of Department of Soil Science and Agril. 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., T 1 (Control), T 2 (15 Kg S ha -1 ), T 3 (30 Kg S ha -1 ), T 4 (45 Kg S ha -1 ), T 5 (60 Kg S ha -1 ), T 6 (FYM 5 t ha -1 ), T 7 (15 Kg S ha -1 + FYM 5 t ha - 1 ), T 8 (30 Kg S ha - 1 + FYM 5 tha -1 ), T 9 (45 Kg S ha -1 + FYM 5 t ha -1 ) and T 10 (60 Kg S ha -1 + FYM 5t ha -1 ). 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. Treatment combination of Sulphur 60 kg ha -1 + FYM 5 t ha -1 S 4 F 1 was recorded maximum 16.63, 12.84 and 29.47 kg ha -1 sulphur uptake by seed, Stover and plant, respectively. Treatment combination of Sulphur 60 kg ha -1 + FYM 5 t ha -1 recorded maximum percentage of Methionine (3.09 mg g -1 ) 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.
