| Abstract/Contents: | "Misuse of fertilizer for turfgrass systems may lead to nutrient leaching which is a growing environmental concern in Florida due to the non-point source pollution draining into waterbodies. Finding new ways to retain and supply nitrogen to growing plants without the sole source of synthetic fertilizers has led researchers to evaluate the use of endophytic N-fixers to help reduce fertilizer inputs. Previous research in non leguminous crops found that exogenous nitrogen requirements can be met with the aid of N-fixing bacteria (Van Deynze et al., 2018; Herridge et al., 2008). Knowledge on the composition of endophytic N-fixing communities in warm-season turfgrass systems is lacking, therefore, inoculation in turfgrass systems has been made with bacterial strains isolated from other crops (Bradshaw & Pane, 2020). The purpose of this research was to identify the presence of endophytic N-fixing bacteria and characterize the stability of the community composition of endophytic N-fixers in warm-season grasses to determine the best maintenance regimes that could lead to less intensive management strategies yielding similar performance on warm-season turfgrasses. In addition, the culturing potential of bacterial strains from three turfgrasses 'CitraBlueTM' St. Augustinegrass [Stenotaphrum secundatum (Waltz)], 'Celebration' bermudagrass [Cynodon. dactylon (L.)], 'Empire' zoysiagrass [Zoysia japonica (Steud)], and three commons weeds in Florida, goosegrass [Eleusine indica (L.) Gaertn], crabgrass [Digitaria sanguinalis (L.) Scoop], and bull paspalum [Paspalum setaceum (Michaux)] was investigated. Results yielded significant differences between microbial communities for height of cut management treatment when controlling for plant tissue and soil effects (p = 0.021). The culture dependent approach helped to create a culture collection, based on the N-fixing potential, using isolates collected from three turfgrasses and two of the common weeds in Florida." |
