Potato ( Solanum tuberosum L. ) is considered one of the most widely consumed crops worldwide, due to its high yield and nutritional profile, climate change-related environmental threats increasing food demand. This scenario highlights need sustainable agricultural practices enhance potato productivity, while preserving maintaining soil health. Plant growth-promoting bacteria (PGPB) stimulate crop production through biofertilization mechanisms with low impact. For instance, PGPB promote biological nitrogen fixation, phosphate solubilization, phytohormones, biocontrol processes. Hence, these microbes provide a promising solution for more productive agriculture. In this study, effects Bacillus amyloliquefaciens QST713 based-product (MINUET™, Bayer) were assessed in terms yield, microbiome, peel petiole nutrient profile as wide range cultivars across United States America. Depending on location, boron content increased after biostimulant inoculation maximum 24% 14%, respectively. Similarly, was greatly improved depending location 73%, 62% 36% manganese, zinc phosphorus. Notably, fungal composition shifted treated group. Yield showed strong associations specific microbial taxa, such Pseudoarthrobacter, Ammoniphilus, Ideonella, Candidatus Berkiella, Dongia . Moreover, local networks strongly associated highlighting important role native microbiome structure indirectly Our results that treatment B. based product correlated enhanced minor impacts diversity. Further studies are suggested disentangle underlying identified patterns associations.
