Abstract: Field experiment was conducted to investigate the effect of foliar nutrition on growth and yield of rainfed blackgram. The treatments viz., foliar spray of 2.0% Urea (T₁), 2.0% MAP (T₂), 1% K₂SO₄ (T₃)_, 0.3% MgSO₄ (T₄), 0.3% MnSO4 (T₅), 0.5% ZnSO₄ (T₆)_, 0.02% Boric acid (T₇), 0.5% FeSO₄ (T₈)_, 0.05% Na₂MoO₄ (T₉), 2.0% 19:19:19 Mixture (T₁₀), Pulse magic @ 10 g/l (T₁₁), Control (T₁₂) and Absolute control (T₁₃). Foliar spray was taken at flowering stage. Basal dosage of fertilizer 25:50 kg N: P₂O₅ ha^-1 was applied to all plots except absolute control. Among the treatments, foliar spray of Pulse magic @ 10 g/l had the profound effect in improving the growth attributes and further, growth attributes are positively co related to seed yield. Consequetly, foliar spray of Pulse magic @ 10 g/l recorded the highest yield of 1101 kg/ha with a yield increment of 23% over control. The yield enhancement might be due to the improvement in growth traits and yield attributes.
