Effect of different levels of Phosphorus and Phosphorus solubilizing bacteria on the growth and yield of soybean (Glycine max L.)

Background: Soybean is an important legume crop that contributes largely to protein and edible oil. The current experimental trial was held study the influence of various phosphorous levels Phosphorous solubilizing bacteria on growth yield attributes soybean [Glycine max. var. Shivalik]. trail conducted sandy loamy soils central plain zone Punjab. Methods: accomplished during Kharif season in year 2021-2022 Shivalik (Himso-333) Variety soybean. In this study, four (50%, 75%, 100%, 125%) combination with (PSB) were used their yield. design followed a Randomized block which consists 7 treatment combinations replicated three times. Result: revealed has shown significant response regard attributes. It observed parameters have increasing trend up 75% P2O5 then decreased from 100% P2O5in all parameters. maximum plant height at 86.4 cm T5 (75%P2O5 + PSB) minimum recorded as 70.9 T1 (Absolute control). Seed 2.03 t/hac by 1.76 T4 (50%P2O5 obtained 1.05 This concluded Biofertilizer can be sustainable Agri-input improve soil health ultimately
