An experiment was carried out in Calcareous Low Ganges River Floodplain Soil (AEZ 12) at Pulses Research Sub-Station (PRSS), Madaripur during Kharif I of 2008 and 2009.The objectives were to evaluate the effect of zinc (Zn) and boron (B) on the yield and yield contributing characters of mungbean (Vigna radiata L. Wilczek) and to find out the optimum dose of Zn and B for yield maximization. There were four levels of zinc (0, 0.75, 1.5, and 3.0 kg/ha and boron (0, 0.5, 1.0, and 2 kg/ha) along with a blanket dose of N20 P25 K35 S20 kg/ha. The experiment was laid out in RCBD with three replications. Results showed that the combination of Zn1.5B1.0 produced significantly higher yield (3058 kg/ha) and (2631 kg/ha, in the year 2008 and 2009, respectively. The lowest yield (2173 kg/ha) and (1573 kg/ha, were found in control (Zn0B0) combination. The combined application of zinc and boron were observed superior to their single application in both the years. Therefore, the combination of Zn1.5B1.0 might be considered as suitable dose for mungbean cultivation in Bangladesh. But from regression analysis, the optimum treatment combination was Zn1.87 B1.24 kg/ha for Madaripur. Keywords: Zinc; boron; mungbean; yield; yield contributing characters.
