Influence of Different Level of NPK and Rhizobium on Physico Chemical Properties of Soil, Growth and Yield Attribute of Blackgram (Vigna mungo L.) Var: Shekhar-2

An experiment was conducted “to determine the influence of different level of NPK and Rhizobium on physico-chemical properties of soil, growth and yield attribute to black gram (Vigna mungo L. var. Shekhar-2) during Zaid season 2023-2024 at the Research farm Department of Soil Science and Agricultural Chemistry, Naini Agriculture Institute , SHUATS, Prayagraj The design applied was 3x3 factorial randomized complete block design having three levels of NPK @ 0, 50 and 100% ha-1 and three levels of Rhizobium @ 0, 50 and 100% ha-1 respectively. The soil samples from experimental site before conducting research operation, revealed that, soil is of sandy loam texture with neutral to alkaline in reaction and significantly highest in treatment T1. The result shows that application of different levels combination of inorganic fertilizers and improved soil chemical properties of black gram.
