A field experiment was conducted during kharif season of 2016 at Crop Research Farm, Department of Agronomy, SHUATS, Allahabad (U.P.). The soil of experimental plot was sandy loam in texture, neutral in soil reaction (pH 7.5), low in organic carbon (0.35%), available N (230 kg/ha), available P (20 kg/ha) and available K (98kg/ha). The treatments comprised of 4 levels of sulphur viz.
S0 (No Sulphur), S1 (40 kg/ as gypsum), S2 (40 kg/ha as single super phosphate) and S3 (20 kg S/ha as gypsum + 20 kg S/ha as single super phosphate) and three levels of iron viz
. F0 (No iron), F1 (0.5% FeSO4, foliar spray at 25 DAS) and F2 (0.5% FeSO4, foliar spray at 45 DAS). There were 12 treatments each replicated thrice. The experiment was laid out in Randomized Block Design. The result showed that maximum plant height (76.40cm) at 60 DAS, number of nodules (78.33) at 30 DAS, dry weight (24.75gm) at 60 DAS, crop growth rate (1.00 g m-2
) at 60 DAS, harvest index (36.32%) grain yield (716.67kg/ha) and stover yield (1372.67kg/ha) were recorded under treatment T5 (40 kg S/ha as gypsum+ 0.5% FeSO4 foliar spray 25 DAS). Maximum net return of Rs 69764.1 and B.C. ratio 2.59 was also recorded in treatment T5 (40 kg S/ha as gypsum+ 0.5% FeSO4 foliar spray 25 DAS).
