Spent mushroom substrate (SMS) is the residual biomass generated after harvesting fruitbodies of edible fungi. It produced in large quantities and contains abundant nutrients. Plant growth-promoting rhizobacteria (PGPR) are a group plant-associated microorganisms known for their ability to enhance plant growth, improve disease resistance, boost soil quality. In this study, three PGPR strains with highest potential were selected based on grow effectively SMS extract. The substrates mixed solutions sterile water establish batch culture system. mixture was initially incubated at 28 °C 3 days, followed by continuous aerobic decomposition ventilated environment 180 days. Based quality analysis PGPR-treated SMS, 54-day treatment transplanting blueberry seedlings selected. showed significantly higher TN, HN, AP than controls (p < 0.05), suggesting role enhancing nutrient availability. Alpha diversity index revealed significant differences microbial between control. Furthermore, influenced growth characteristics, content, rhizosphere diversity. Enhanced characteristics strongly correlated increased levels, link rhizospheric communities performance. This study provides novel approach experimental framework utilization development PGPR-based biofertilizers, offering valuable insights into sustainable agricultural practices.
