The utilization of Plant Growing Promoting Bacteria (PGPR) holds significant importance in agricultural systems, especially as a biofertilizer. This study aimed to select effective PGPR for maize to improve yield and nutrient content in a greenhouse pot experiment. Forty-five bacteria were isolated from three different ecosystems as forest, organic farm site, and pasture. The results indicated that PGPR application increased macro nutrients ranging from 12.5% to 50% compared to the control. With the PGPR isolated from forest application, the micronutrient content of Fe, Zn, Mn, and Cu in maize increased around 100%, 20%, 60%, and 100%, respectively. In terms of physiological parameters such as fresh and dry biomass weight, plant height and stem diameter in maize plants were statistically significant than the control treatment. The results proved that PGPR isolated from various ecosystem applications had a more stimulating impact on macro micronutrient content and physiological parameters in maize plants than non-PGPR applications. In general, organic farming sites would be the more promising starting point for PGPR isolation.
