Abstract: Experiments were conducted to know the effect of foliar application of zinc and boron on vegetative growth, fruiting efficiency and yield in Field bean. Pot experiment was conducted during winter season (October to January) and field experiment was conducted in summer season (April to July) at University of Agricultural Sciences, GKVK, Bengaluru. Results revealed that foliar application of zinc @0.5% and boron @0.2%, 45 days after sowing increases plant height, number of branches and biomass. The number of flowers formed per plant and fruiting efficiency also increases and flower drop decreases significantly. Further, foliar spray of zinc and boron showed increased test weight and seed yield per plant. Fruiting efficiency was also found to be positively correlated with the number of pods and seed yield. Interestingly individual nutrient spray showed positive response whereas combined spray yield no such responses.
