Co-inoculation of soybeans with Bradyrhizobium and plant growth-promoting bacteria has displayed promise for enhancing growth, but concrete evidence its impact on soybean yields is limited. Therefore, this study assessed the comparative efficacy two 1-aminocyclopropane-1-carboxylate deaminase-producing Pseudomonas species (OFT2 OFT5) co-inoculated ottawaense (SG09) physiology, nodulation efficiency, grain yield three major Japanese cultivars: Enrei, Fukuyutaka, Satonohohoemi. The experiments were conducted in a warehouse under natural light conditions. treatments included inoculation SG09, SG09 + OFT2, OFT5. Compared alone, co-inoculation led to significant improvements physiological performance Enrei Fukuyutaka cultivars, not Satonohohoemi cultivar. Furthermore, significantly boosted total nitrogen content ion uptake shoots, ultimately leading remarkable improvement cultivars. These findings contribute clarifying interplay among Bradyrhizobium, Pseudomonas, host Notably, Bradyrhizobium–Pseudomonas represents potentially effective biofertilization strategy production, highlighting promising avenues sustainable agricultural practices.
