A field trial was carried out in kharif season of 1998 and 1999 to find out the effect of different Bradyrhizobium strains on growth and yield of green gram under mid-hill conditions of Himachal Pradesh, The seed inoculation treatment influenced the plant height and dry matter accumulation at all stages of crop growth. Local culture of Bradyrhizobium provided significantly maximum value in these characters, foUowed by R1, R3 strain and lowest increase was noticed in control. The number of branches and pods per plant were also affected by Bradyrhizobium inoculation. No strain could influence the number of cluster per plant in mungbean. Local isolate of Bradyrhizobium proved best under agroclimatic conditions of experimental area and showed significantly highest yield as compared to other strains and control.
