Interactions of Azospirillum brasilense and Bacillus megaterium var. phosphaticum and Glomus fasciculatum in the rhizosphere of tomato plants were studied. There was no significant difference in plant growth parameters between VAM-inoculated treatments. Plants inoculated with the phosphobacteria had significantly higher shoot length, which was equivalent to VAM and other VAM + phosphobacteria combinations. Azospirillum or phosphobacteria alone increased plant biomass compared with the uninoculated control. VAM index was significantly reduced with the addition of phosphobacteria. There was no difference in tissue nutrient concentrations between treatments.
