Abstract: A field experiment was conducted during kharif 2015 at the experimental farm, Tirhut College of Agriculture, RPCAU, Pusa, Bihar to study the effect of micro and secondary nutrients on growth, yield and quality of blackgram (Vigna mungo (L.) Hepper) The experiment was laid-out in a randomized block design (RBD) with eight treatments, each having four replications. The treatments were T₀: RDF (control), T₁: RDF + B, T₂: RDF + Zn, T₃: RDF + S, T₄: RDF + B + Zn, T₅: RDF + B + S, T₆: RDF + Zn + S and T₇: RDF + Zn + B + S. Uniform basal application was made with 20 kg N ha^-1, 40 kg P₂O₅ ha^-1, 20 kg K₂O ha^-1 through urea, DAP and MOP, respectively. Sulphur, Zn and B were applied @ 20, 5 and 1.5 kg ha^-1 from Bentonite-S, Zinc sulphate and Di-sodium tetra-borate pentahydrate, respectively. Yield attributes characters, grain yield kg ha^-1, straw yield kg ha^-1, protein content and protein production of blackgram was significantly affected due to various treatments.
