Abstract

An experiment was conducted during in Zaid season (March 2022-June 2022) to study the “effect of different levels of NPK and Zinc on soil health in black gram (Vigna mungo L.)” on central research farm of Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj. A randomized block design was used to set up the experiment, with three levels of NPK (0%, 50%, and 100% NPK) and three levels of zinc (0%, 50%, and 100% zinc). The outcome demonstrates that inorganic fertilizer application had a non-significant effect on soil physical-chemical parameters (BD, PD, pH, EC and OC)  and significant increase in pore space, water holding capacity, available nitrogen, phosphorus, potassium and zinc in treatment T9 [NPK at 100% + zinc at 100%]  than other treatments.
