The present investigation titled “Integrated Nutrient Management (INM) on Yield Attributes of Black gram (Vigna mungo L. Hepper)” in the Malwa Region (M.P.) was conducted at Crop Research Cafeteria, under Mandsaur University, Mandsaur(Madhya Pradesh). A randomized block design with 8 treatments and 3 replications was followed. Black gram variety T-9 was sown at 15 kg ha⁻¹.The treatments included T₁: Control, T₂: 100% RDF + Rhizobium, T₃: 100% Vermicompost + Rhizobium, T₄: 75% Vermicompost + 25% RDF + Rhizobium, T₅: 50% Vermicompost + 50% RDF + Rhizobium, T₆: 100% NADEP + Rhizobium, T₇: 75% NADEP + 25% RDF + Rhizobium, and T₈: 50% NADEP + 50% RDF + Rhizobium. Treatments included control, 100% RDF + Rhizobium, 100% Vermicompost + Rhizobium, and combinations of Vermicompost or NADEP with RDF + Rhizobium. At 45 DAS, the maximum plant height was recorded in T₆(100% NADEP + Rhizobium) with 60.33 cm. At harvest, the highest plant height was again recorded in T₆(64.14 cm). The highest plant population was also recorded under T₆(18.00 plants m⁻²). The maximum relative growth rate (RGR) was recorded under T₆(0.049 g g⁻¹ day⁻¹). Crop growth rate (CGR) was highest in T₆(12.73 g m⁻² day⁻¹), followed by T₈(12.26 g m⁻² day⁻¹) and T₄(11.66 g m⁻² day⁻¹), whereas the lowest CGR was recorded in the control treatment T₁(8.06 g m⁻² day⁻¹). Overall treatments T₈(50% NADEP + 50% RDF + Rhizobium), followed by T₅(50% Vermicompost + 50% RDF + Rhizobium), T₆(100% NADEP + Rhizobium) and T₇(75% NADEP + 25% RDF + Rhizobium). However, T₁ reported the lowest values in most of the parameters.
