The experiment was carried out during rabi season during years 2019-20 and 2020-21 at the Research cum Instructional Farm of Indira Gandhi Krishi Vishwavidyalaya, Raipur, Chhattisgarh. The experiment was laid out in factorial randomized block design with four nitrogen levels (N0, N45, N90 and N135 kg N ha-1) and four sulphur levels (S0, S15, S30 and S45 kg S ha-1) comprising sixteen treatment combinations with three replications. The soil of the experimental site found neutral to alkaline in reaction (pH 7.13), non-saline (0.21 dS m-1) in nature, medium in organic carbon (5.13 g kg-1), low in available nitrogen (224 kg N ha-1), medium in phosphorus (13.26 kg P2O5 ha-1), high in available potassium (345.19 kg K2O ha-1), medium available sulphur (21.35 kg S ha-1) and clayey in texture. Applied treatments nitrogen and sulphur levels highest seed yield, stover yield, B:C ratio were recorded with 135 kg N ha-1 & 45 kg S ha-1. In applied N and S levels highest NUE 45 kg N ha-1 & 45 kg S ha-1 and SUE 90 kg N ha-1 & 15 kg S ha-1 and in lowest was found under control
