The present investigation titled “Effect of levels of phosphorous and sulphur on growth and yield of Blackgram (Vigna mungo L.)” was conducted at Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj during zaid season of 2019. Shekhar-2 variety was selected for conducting the trial. The experiment was laid out in Randomized Block Design consisting of 9 treatments replicated thrice with the treatment combination of three levels of phosphorus viz.,P1 – 30 kg ha-1, P 2 - 40 kg ha-1, P 3- 50 kg ha-1 and three levels of sulphur viz.,S 1- 20 kg ha-1, S 2- 25 kg ha-1, S 3- 30 kg ha-1. The results revealed that the treatment T6 (P at 40 kg ha-1+S at 30 kg ha-1) recorded maximum plant height (32.77 cm), number of nodules per plant (18.56), dry weight (11.92 g plant-1), Crop Growth rate (CGR) (0.703g m-2day-1), number of pods per plant (24.51), number of grains per pod (6.40), test weight(47.60 g), grain yield (2.76 t ha-1) and protein content (24.28%). However, the maximum stover yield (6.22 t ha-1) was obtained with the treatment T5 (P at 40 kg ha-1+ S at 25 kg ha-1). Maximum gross return (₹124200 ha-1), net return (₹82422.58 ha-1) and B:C ratio (2.97) was recorded with the treatment T6 ( P at 40 kg ha-1+S at 30 kg ha-1).
