Response of Different Levels of NPK and Zinc on Soil Health in Black Gram (Vigna mungo L.)

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