ABSTRACT
The purpose of this work was is to evaluate the correlation of soil physical attributes with integrated nutrient management in vertisols. The experiment was conducted in Randomized complete Block Design with three replications and eight treatments consist of Control (T1), 25% RDF+ V-A (T2), 25% RDF+ V-B (T3), 25% RDF+ V-C (T4), 50% RDF+V-A (T5), 50% RDF+V-B (T6), 50% RDF+ V-C (T7) and 100% RDF (T8). The 50% NPK + vermicompost –C (13.89 %) treatment had the highest gravimetric moisture content followed by 50% NPK + V-A (13.45) and lowest in control (12.88%). The reduction in bulk density 1.32 Mg m-3, 1.33 Mg m-3 at flowering had harvesting stage of crop respectively recorded in 50% NPK + V-A treatments as compare to other treatments. The 50% NPK + V-A (1.09 cm hr -1 ) treatment had the highest hydraulic conductivity followed by 100% NPK treatments (1.06 cm hr -1) and lowest values are recorded in control ( 0.82cm hr -1 ). The highest coarser aggregates recorded in 50%NPK + V-B (44.01) , 50% NPK + V-A (40.35) followed by 50% NPK+ V-C (39.04) and lowest values are recorded in control ( 22.55). 50% NPK + V-A expressed higher yield (33 q ha-1) over other treatments during period of investigation. Based on the results of this study it is clear that with the use of Integrated nutrient management we can minimize the quality of fertilizers, therefore results in safer environment and sustainable soil fertility.
