| Summary: | One of the main causes of climate change is the emission of GHGs, and one of the sources for the generation of such gasses is agriculture via plant production. Considering the foregoing, a study was conducted to assess PGPRs in strawberry cultivation which were able to limit GHG emissions. The first experimental factor was the inoculation of plant roots with the <i>Bacillus</i> sp. strains DLGB3, DKB26, DKB58, and DKB 84; the <i>Pantoea</i> sp. strains DKB63, DKB64, DKB65, and DKB68; <i>Azotobacter</i> sp. AJ 1.2; and <i>Pseudomonas</i> sp. PJ 1.1. The second experimental factor constituted the different moisture levels of the growth substrate. In the experiment, emissions of NH<sub>3</sub>, CO<sub>2</sub>, N<sub>2</sub>O, and CH<sub>4</sub> were measured. In light of the conducted research, five strains were selected (<i>Azotobacter</i> sp. AJ 1.2; <i>Pantoea</i> sp. DKB64, DKB63, and DKB68; and <i>Pseudomonas</i> sp. strain PJ 1.1) that showed the greatest potential for reducing GHG emissions depending on the prevailing environmental conditions. The application of the tested bacterial strains under different moisture conditions in the substrate either reduced or did not affect GWP. This research on PGPR, which was conducted to select strains of rhizosphere bacteria that would be able to reduce GHG emissions, may form the basis for creating an inoculum and can be employed as an effective strategy for mitigating certain abiotic stresses.
