Field experiments were conducted in 1994/95 and 1995/96 growing seasons to study the influence of two bradyrhizobia treatments, five molybdenum treatments and five zinc treatments on groundnut yield and its components. Data on pod yield/ha, pod number/plant and seed yield/ha were collected at harvest. Under the drought conditions of the first season, the Bradyrhizobium treatment did not affect the crop yield,but and the introduced strain "IC7001" gave higher values of number of pods/plant, pod yield/ha and seed yield/ha than the control. However, under the favourable conditions of the second season, the indigenous strains subjected plants (the control) gave the highest values of these traits and significantly out yielded those inoculated with IC7001 strain in the number of pods/plant and pod yield/ha. The lowest soil Zn (i.e., 2.79 ppm, control) significantly produced higher values of pod yield/ha and seed yield/ha in 1994/95 and 1995/96 season s, respectively. Also, the highest pod and seed yields were obtained from the interaction of the lowest soil Zn application and the indigenous strains-subjected plants. In general, higher Mo application did not affect yield as compared to the soil Mo treatment
