The experiment was carried out in Acidic Northern and Eastern hills Soil (AEZ 29) at Regional Agricultural Research Station (RARS), Akbarpur, Moulvibazar during Kharif 1 of 2012 to observe the effect of zinc (Zn) and boron (B) on the seed yield and yield contributing characters of mungbean.There were four levels of zinc (0, 1.0, 2.0, and 4.0 kg/ha) and boron (0, 0.75, 1.5, and 3.0 kg/ha) along with a blanket dose of N24 P20 K30 S15 kg/ha.Experiment was laid out in RCBD with three replications.Incase of zinc application, highest seed yield (1.418 ton/ha) was obtained from 1.0 kg Zn/ha which was statistically similar (1.358 t/ha) with dose 1.0 kg Zn/haand but significantly higher (1.034 t/ha) than the control.Again for boron application,the highest seed yield (1.550 t/ha) was found from the treatment 1.50 kg B/ha which was statistically identical with 3.0 kg B/haand the lowest (0.927 t/ha) for control.The combined application of zinc and boron showed significant effect on mungbean yield than the single application of zinc and boron.Results showed that the combination of Zn1.0B1.5 produced significantly higher yield (1.677ton/ha) than the control (Zn0B0) combination (0.64 ton/ha).Combined application of zinc and boron were observed superior to their single application.Therefore, the combination of 1.0 kg zinc per hectare and 1.5 kg boron per hectaremight be considered as suitable dose for mungbean cultivation in acidic soil of Sylhet region of Bangladesh.
