An experiment was conducted to evaluate the direct effect of different level of sulphur (S) alone or in combination with organic manures on mustard in calcareous soil of north India. Sulphur application significantly increased the S concentration and its uptake by mustard (seed+stover). The optimum level of S was found to be 60 kg S ha-1 in conjoint with 5 t Bio Gas Slurry (BGS) ha-1 for mustard crop with respect to concentration and nutrient uptake. The maximum total N, P and K uptake of 69.5, 21.2 and 85.7 kg ha-1 respectively was recorded at 60 kg S ha-1 showing the synergistic behaviour at lower level of S-application with N, P and K content in seed and stover and antagonistic at higher level of S-application. The beneficial effect of organic manure was also apparent in increasing total N, P and K uptake from 51.9 to 56.6, 15.9 to 19.6 and 66.8 to 73.4 kg ha-1, respectively. Biogas slurry (BGS) proved better as compared to FYM in increasing total N, P and K uptake by mustard. The optimum N: S ratios were worked out to be 3.57 and 1.72 in mustard seed and stover, respectively. The optimum P: S ratios for mustard seed and stover were 1.53 and 0.37, respectively. Sulphur application enhanced the protein content in mustard seed from 13.5 per cent to 18.2 per cent.
