CORRELATION EFFECT AMONG THE PHYSICO-CHEMICAL PROPERTIES OF SOIL, MORPHOLOGICAL PARAMETERS AND BIOLOGICAL CONSTITUENTS AFTER APPLYING NPK WITH RHIZOBIUM ON BLACK GRAM (VIGNA MUNGO L.) IN INCEPTISOLS OF PRAYAGRAJ.

A field study was conducted at the Department of Soil Science and Agricultural Chemistry research farm SHUATS in Prayagraj during the Kharif season 2018-2019. There were nine treatments in the trial, which was set up in a 3x3 randomized block design with three replications. The physicochemical parameters of the experimental field's soil revealed that it is an inceptisol given treatment T9 @ (100% NPK + 100% Rhizobium) was shown to be the best in post-harvest data based on mean performance. In terms of growth and yield there was a huge improvement. The correlation was observed between the physical and chemical properties of soil, physicochemical parameters with biochemical constituents and morphological parameters in which B.D represents a negative significant correlation with all other parameters and other parameters represent a positively significant correlation with each parameter.
