Abstract: The experiment was conducted with ten treatments and three replications in Randomized Completely Block Design. The treatment consisted ten different concentrations of Calcium and micro-nutrients along with recommended dose of fertilizers viz. T₀: RDF + control (water spray), T₁: RDF + CaCl₂ @ 0.4%, T₂: RDF + CaCl₂ @ 0.6%, T₃: RDF + CaCl₂ @ 0.8%, T₄: RDF + ZnSO₄ @ 0.4%, T₅: RDF + ZnSO₄ @ 0.6%, T₆: RDF + ZnSO₄ @ 0.8%, T₇: RDF + FeSO₄ @ 0.4%, T₈: RDF + FeSO₄ @ 0.6% and T₉: RDF + FeSO₄ @ 0.8%. The data revealed that the highest yield (426.14 q/ha) was obtained under the treatment T₅ (RDF + ZnSO₄ @ 0.6%), which was found 42 per cent more over control followed by treatment T₈ (RDF + FeSO₄ @ 0.6%). Similarly the highest benefit: cost ratio (4.16:1) was registered under the superiority of treatment T₅ whereas the minimum benefit: cost ratio (2.03:1) was noticed under the treatment T₀.
