Abstract/Contents: | "Plant growth promoting rhizobacteria (PGPR) can co-exist within the roots of plants and in the soil rhizosphere to enhance turf performance and stress tolerance. Previous research has demonstrated success in using PGPR to inoculate turfgrass in controlled environment conditions; however effective field inoculation is more challenging due to the presence of native soil organisms and fluctuating environmental conditions. These factors can prevent efficient colonization and establishment of the new strains of bacteria, thus limiting their ability to improve plant growth and stress tolerance. This study used a novel combination of growth promoting Burkholderia bacteria strains (ACCdR23+14) to inoculate creeping bentgrass (Agrostis stolonifera) field plots maintained at fairway height (1.2 cm). This novel combination of PGPR was mixed into a 0.01% humic acid solution and applied as a soil drench. Non-inoculated control plots and plots treated with a commercially available inoculant were used for comparison. After inoculation, the plots were subjected to 49 days of drought stress (60% ET) using a rain-out shelter, followed by re-watering and a 28-day recovery period. Weekly physiological measurements and digital images were collected throughout the 2020 growing season. Treatment with ACCdR23+14 resulted in higher turf quality, percent green cover, normalized difference vegetation index (NDVI), and dark green color index (DGCI) during the drought and recovery periods. These results suggest that this novel combination of PGPR strains has the potential for development as a biofertilizer to improve drought tolerance and reduce water use in creeping bentrgrass." |
