Assessment of different level of macro-micro nutrients and rhizobium on soil health parameters and yield of blackgram (Vigna mungo L.) var. Shekhar-2

Abstract

An experiment was conducted during in Kharif season (July 2023 - August 2023) to study the “Assessment of different level of Macro-micro Nutrients and Rhizobium on Soil health Parameters and Yield of Blackgram (Vigna mungo L.) var. Shekhar-2” 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 results shows 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 @ 100% + Zinc @ at 100%] that found to be at par than any other treatments than other treatments.
