Abstract:
A field trial was carried out during kharif season of 2021 to evaluate the “Response of varying level of inorganic fertilizers (N P K, & Zn), farm yard manure and rhizobium inoculation on soil health and yield attributes of black gram (Vigna mungo L.) var. Shekhar-2” in sandy loam soil. The experiment was laid down in randomized block design comprised three fertility levels (control, @ 100% RDF, @50% Zn, @ 100 % FYM) and three levels of farm yard manure (control, @ 50% FYM, @ 100% FYM) replicating thrice and rhizobium inoculation. Amongst the fertility levels, the application of @100 % RDF, (20 kg N ha^-1 60 kg P₂O₅ ha^-1 20 K₂O ha^-1), 100% Zn (25 kg Zn ha^-1) and 100% (10 t FYM ha^-1) significantly increased seed yield of black gram. Although, the seed yield in 100 % RDF, 100 % Zn, 100 % FYM and in 50 % was at par with 100% RDF. Similarly, seed inoculation with Rhizobium significantly increased seed yield over the remaining treatments. The interaction effect of fertility levels and biofertilizer significantly influenced the yield and of black gram maximum being with 100% RDF, Zn, FYM and Rhizobium combination.
