The extensive use of chemical fertilizers has served as a response to the increasing need for crop production in recent decades. While it addresses demand food, resulted decline productivity and heightened negative environmental impact. In contrast, plant probiotic bacteria (PPB) offer promising alternative mitigate consequences fertilizers. PPB can enhance nutrient availability, promote growth, improve uptake efficiency, thereby reducing reliance on fertilizers.This study aimed evaluate impact native Rhizobium strains, specifically calliandrae LBP2-1, mayense NSJP1-1, jaguaris SJP1- 2, quality, rhizobacterial community tomato crops. Various mechanisms promoting growth were investigated, including phosphate solubilization, siderophore production, indole acetic acid synthesis, cellulose cellulase production. Additionally, involved assessment biofilm formation root colonization by GFP-tagged conducted microcosm experiment, analyzed microbial using metagenomics rhizospheric soil.The results showed that rhizobial strains NSJP1-1 SJP1-2 had ability solubilize dicalcium phosphate, produce siderophores, synthesize acid, colonization. Inoculation plants with influenced fruit microbiome composition. Metagenomic analysis increased Proteobacteria abundance altered alpha diversity indices, indicating changes bacterial community.Our findings demonstrate potential have be used agricultural crops generation safe food high nutritional value.
