Influence of NPK and poultry manure on physico-chemical properties of soil in cowpea

Abstract

The research was lead at the Soil Science Research Farm, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj, U.P. during the Rabi season in 2023-2024. The experiment was laid out in Randomized Block Design with eighteen treatments and three replications with four levels of NPK and poultry manure and one level of rhizobium respectively that leads to the Nitrogen, Phosphorus and Potassium (kg ha-1), OC%,% pore space and water holding capacity (%) of soil after crop harvest was found significant except on bulk density (Mg m-3), particle density (Mg m-3), pH and EC (dSm-1) of soil after harvest. The treatment T16 (@ 105% NPK + @ 30% Poultry Manure + Rhizobium Inoculation) in soil have significant findings which comprises yellowish brown and sandy loam textured neutral to alkaline soil that is non- saline in nature. Physico-chemical properties of soil was found best in treatment T16 (@ 105% NPK + @ 30% Poultry Manure + Rhizobium Inoculation) as compare with in treatment T1 (@ 0% NPK + @ 0% Poultry Manure + Rhizobium Inoculation).
