Mapping Global Research Trends on Plant Growth-Promoting Bacteria (PGPB) as Biofertilizers, Biostimulants, and Bioprotectants: A Bibliometric Analysis. In: Herlinda S et al.

Plant Growth-Promoting Bacteria (PGPB) offer a promising innovation to address these constraints, functioning as biostimulants, biofertilizers, and bioprotectants. This study aimed to map the global scientific landscape of PGPB through a bibliometric approach, with the hypothesis that PGPB have become a key strategy in sustainable agriculture, particularly on suboptimal land. Data were retrieved from the Scopus database for the period 1989–2025 and analyzed using Biblioshiny and VOSviewer to evaluate publication trends, journal productivity, collaboration networks among authors, institutions, and countries, as well as the evolution of research keywords. The results indicate a marked increase in publications since 2010, with India, China, and the United States as the leading contributors. Dominant keywords emphasize abiotic stress resistance, biocontrol, rhizosphere interactions, and applications of PGPB in sustainable agriculture. The findings suggest that PGPB research addresses not only microbiological mechanisms but also practical applications to enhance productivity on suboptimal soils. This study provides a scientific foundation for academics, policymakers, and practitioners in directing future research and strategies for harnessing PGPB to support global food security.]]>
