The Department of Agronomy at SHUATS in Prayagraj (UP) on soil with sandy loam in texture to find out the effect Sulphur and Molybdenum on Growth and Yield of Black gram. The treatments consist of three doses of Sulphur viz., 30 kg ha -1 , 40 kg ha -1 and 50 kg ha -1 and Molybdenum 0.5 kg/ha, 1 kg/ha, foliar molybdenum 1500 ppm whose effect is observed on Black gram (var. Shekhar 2). The experiment was laid out in Randomized Block Design with Ten treatments replicated thrice. The treatment with application of Sulphur - 50 kg/ha+ Foliar Molybdenum 1500 ppm recorded significantly higher plant height (53.77 cm), number of branches plant -1 (15.33) and plant dry weight (23.68 g), number of pods per plant (26.27), number of seeds per pod (9.53), test weight (30.52 g), seed yield (1.37 t ha -1 ) and Straw yield (2.95 t ha -1 ) compared to other treatment combinations.
