Abstract/Contents:"Plant growth promoting rhizobacteria (PGPR) have been shown to reduce fertilizer requirements, increase drought tolerance, and mitigate pest pressure in various crops. Less research has been done in turfgrass systems, but results indicate that PGPR can increase growth in bermudagrass; increase growth and nutrient availability and uptake in creeping bentgrass; and increase color rating and clipping yield in perennial ryegrass and tall fescue, though not in Kentucky bluegrass. The goal of this research was to determine whether PGPR affect drought response of creeping bentgrass turf. The trial was conducted at the Utah State University Research Greenhouse in Logan, UT on 'Penncross' and '007' creeping bentgrass. Treatments for each bentgrass cultivar included 1) PGPR Blend 20, 2) PGPR blend DH44, 3) a fertilized control, and 4) an unfertilized, irrigated control. PGPR blends were applied as 500 mL m-2 of the aqueous PGPR suspension of 1 x 107 colony forming units (CFU) mL-1. Treatments were applied once weekly for five weeks. Clippings were collected before treatment and again after final treatments were applied to determine relative water content. After final treatments were applied, half of each treatment were subjected to drought stress and half of each treatment continued to be irrigated. Photos of each pot were taken daily during the drought period using a light box, and images were digitally analyzed to determine percent green cover. The number of days to reach 75, 50 and 25% green cover was recorded. During the dry-down period, clippings were collected to determine relative water content."
