The study was initiated to determine the influence of VAM fungi on a Rhizobium- legume interaction. The pot culture and Leonard jar experiment was conducted during rabbi season with seed of Phaseolus mungo L. and Phaseolus aconitifolius Jacq. The different inoculations of Rhizobium and Mycorrhizae were incorporated. During the period of experiment, samples were analyzed for nodule numbers, dry weight of nodules, fresh weight, dry weight of plant, yield of pods, and length of plant and percentage of Mycorrhizal colonization. The results revealed that dual inoculation of Rhizobium with VAM enhanced seed yield of black gram and Turkish gram.
