Effect of Phosphorus and Potassium on Growth and Yield of Black Gram (Phaseolus mungo L.)

A field experiment was conducted during Zaid season 2023 at Crop Research Farm, Department of Agronomy, Sam Higginbottom University Agriculture, Technology and Sciences, Prayagraj, Uttar Pradesh, India. The soil the experimental sandy loam in texture, slightly alkaline reaction (pH 8), low level organic carbon (0.28%), available N (219 kg/ha), P (11.6 kg/ha) K (217.2 kg/ha). randomized block design consisting 10 treatments with 3 different levels phosphorus 40 kg/ha, 50 60 kg/ha potassium 25, 30 35 three replications were allocated randomly each replication. On topic “Effect on growth yield black gram (Phaseolus mungo L.)”. results showed that T9 application (60 + (35 recorded significantly higher plant height (43.81cm), nodules (40.11), dry weight (8 g), maximum crop rate (8.5 g/m2/day), number pods/plant (36.61), seed (1115.62 t/ha) compared to other treatments. gross returns (98297.69 INR/ha), net (64701.09 INR/ha) benefit ratio (1.93) (60kg/ha) as Minimum parameters treatment control plot RDF 20:40:20 NPK.
