POTENCIAL DE Pantoea agglomerans COMO BIOFERTILIZANTE NA CULTURA DO MILHO (Zea mays L.): UMA REVISÃO DE ESCOPO

Abstract

Modern agriculture faces the challenge of reducing dependence on mineral phosphate fertilizers, which are finite resources and often exhibit low efficiency due to rapid immobilization in the soil. In this context, phosphorus-solubilizing microorganisms have emerged as a biotechnological alternative to promote more sustainable production systems. The present study consists of a scoping review aimed at mapping and synthesizing the available scientific evidence regarding the use of the bacterium Pantoea agglomerans as a biofertilizer in maize cultivation. The methodology involved a bibliographic survey in the Web of Science and Scopus databases, resulting in the selection of 15 articles for detailed analysis. The results demonstrate that P. agglomerans acts as a multifunctional plant growth-promoting bacterium (PGPB), employing mechanisms such as the solubilization of phosphorus, zinc, and potassium, the production of phytohormones (especially indole-3-acetic acid – IAA), and biological nitrogen fixation. The application of this bioinput in maize resulted in significant increases in biomass, plant nutritional content, and grain yield, in addition to contributing to tolerance to abiotic stresses such as drought and salinity. It is concluded that P. agglomerans has high potential for inclusion in commercial biofertilizers. However, there are still knowledge gaps related to performance consistency under field conditions and the need for large-scale studies to validate its commercial effectiveness.
