Plant growth-promoting rhizobacteria (PGPR) play an important role in promoting plant growth and increasing crop yield. Bacillus cereus DW019, which was previously isolated from ion-absorbed rare-earth ore of Ganzhou Southeastern China, has been considered as a PGPR due to its production indole-3-acetic acid (IAA), ammonia siderophore, but effect on plants remains poorly understood. In this study, autoclaved dead cells viable DW019 at different concentrations were inoculated into pot-cultivated cherry tomato (Lycopersicon esculentum) investigate the A total 70 days after inoculation, fruits harvested, their indicators, yields, nutrients measured. The results showed that biomass, stem thickness, height root length significantly promoted vitamin C, soluble sugar protein increased. Inoculation with also modulated rhizospheric microbial community diversity structure, especially proportions Proteobacteria Actinobacteriota, turn improved height, fresh weight, nutritional quality rhizosphere soil bacterial tomato. All findings suggest is beneficial crops improves yield tomato, suggesting could be developed potential biofertilizer used agricultural inoculant increase improve ecosystem.
