Impact of Integrated Nutrient Management Practices on Soil Health Parameters and Yield Attributes of Soybean (Glycine max L.) var. JS-9560 in Inceptisol of Alluvial Soil, District Prayagraj, Uttar Pradesh

Abstract

A field trial was carried out during the Kharif season 2021-22 at the Research farm, of Naini Agriculture Institute Prayagraj India. The experiment was laid down in randomized block design comprised three fertility levels control NPK @ 100%, Rhizobium + PSB @ 100%, Vermicompost and Sulphur @ 100%, 75% and @ 50% respectively replicating thrice and rhizobium phosphate solubilizing bacteria (PSB) inoculation. Among the fertility levels, the application of 100% N, P, K, 40 kg N ha-1, 60 kg P2O5 ha-1, 40 kg K2O ha-1 and 100% Vermicompost 5 t ha-1, Sulphur 20 kg ha-1 in the experiment. It was concluded that the texture of soil sandy loam, the soil health parameters respectively Bulk density ranged between 1.21 to 1.31 Mg m-3, Particle density 2.08 to 2.50 Mg m-3 Pore space 45.12% to 51.23% water holding capacity 36.14% to 62.06% Organic carbon 0.319% to 0.613%, soil pH ranged between 7.34 to 7.78, EC ranged between 0.157 to 0.265 dsm-1, Nitrogen 182.56 to 320.75 kg ha-1, Phosphorus 16.12 to 33.67 kg ha-1, Potassium 182.24 to 238.76 kg ha-1, Sulphur 16.03 to 29.58 mg kg-1, It was observed that for post-harvest, treatment T9 was best in yield attributes plant height 97.18 cm, number of branches plant-1 7.1, 5, pods plant-1 74.83, seed pod-14.44 and seed yield (2337.25 kg ha-1) T9 were to be found best treatment combination.
