Influence of foliar nutrition on growth and yield of blackgram under rainfed condition

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.
