“…Thus, a high proportion of soybean nodules were found to be occupied by two strains of Rhizobium japonicum [6]. The ability of some strains of the cowpea group to compete with other strains and nodulate the mung bean (Vigna radiata (L) Wilczek) effectively depends on the soil type [7]. There is, however, a lack of information on the nodule occupancy by the inoculated rhizobial strains on the mung bean.…”

Field experiments in rice fallow soil with two Rhizobium strains, VUW.2 and VRS.6, showed that both were capable of competing with native rhizobia in infecting the roots of the mung bean and occupying the nodules to an extent of 35–75%. Simultaneous infection with both strains was most effective in increasing growth and nodulation efficiency. It was also observed that the inoculated rhizobial strains increased the grain yield 18.7–23.6% above control. The maximum increase of 23.6% in grain yield was obtained from seeds inoculated with both strains simultaneously.
