Influence of Phosphorus and Bio-fertilizers on Growth and Yield of Black Gram (Phaseolus mungo L.)

Abstract

The field study took place in kharif 2022 at the Crop Research Farm, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology, and Sciences, Prayagraj (U.P.). to determine the “Effect of Phosphorus and Bio -fertilizer on growth and yield of black gram (Phaseolus mungo L).” The results revealed that treatment -9 [Phosphorus -50 kg/ha + Rhizobium +PSB] significantly increased plant height (45.69 cm), number of nodules/ plant (38.15), plant dry weight (6.64 g), Crop growth rate (2.99 g/m2/day), number of pods/plant (40.8), maximum number of seeds/pod(6.23), test weight (34.75 gm), seed yield (1371 kg/ha), stover yield (2980 kg/ha), gross return (INR 89,290.00/ha), and net return (INR 60,797.00/ha). also, the maximum B:C ratio (2.13) was taken captive in treatment-9[ phosphorous 50 kg/ha + Rhizobium + PSB] in comparison to different treatments.
