The present investigation titled “Effect of levels of phosphorous and zinc on growth and yield of Greengram (Vigna radiata 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. Samrat 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 – 45 kg ha-1, P 2 - 60 kg ha-1, P 3- 75 kg ha-1 and three levels of zinc viz., Z1-15 kg ha-1, Z2- 20 kg ha-1, Z3- 35 DAS and 45 DAS (0.5% foliar spray). The results revealed that the treatment T6 [P at 60 kg ha-1+ Zn at 35 DAS and 45 DAS (0.5% foliar spray)] recorded maximum plant height (45.37 cm), number of branches per plant (13.07), number of nodules per plant (16.22), dry weight (10.55 g plant-1), Crop Growth rate (0.299 g m-2 day-1), number of pods per plant (27.16), number of grains per pod (13.64), grain yield (2.18 t ha-1), stover yield (5.15 t ha-1) and protein content (25.41%). Maximum gross return (₹108777.7 ha-1), net return (₹71992.72 ha-1) and B:C ratio (2.96) was recorded with the treatment T6 [P at 60 kg ha-1+Zn at 35 DAS and 45 DAS (0.5% foliar spray)].
