| Abstract/Contents: | "Late-season nitrogen management for non-overseeded bermudagrass golf course fairways is an area that has not been fully examined and remains poorly understood. While recent work has investigated bermudagrass responses to fall nitrogen in transition zone climates, little to no work has been conducted in the warm-humid regions of the southern United States. Fall fertilization can be highly beneficial to warm-season turf in terms of fall color retention and increasing carbohydrate reserves for winter and early spring months. This study is being conducted at Texas A&M University Turfgrass Field Laboratory on Latitude 36 bermudagrass. Five late-season N application approaches are being tested, based on the first historical frost date for the region and corresponding to nightly low temperatures. Fertility regimes include 4.9 g m2 applied either early fall, mid-fall, or late fall. Two split application timings are also being evaluated, including a 1 g m2 monthly (Oct-Feb) winter spoon-feeding and a 1.6 g m2 bi-monthly application. In addition, N sources including 15N-labeled urea, methylene urea, urea formaldehyde, and combinations of the two are being evaluated. Over the first winter, significant differences in late fall/winter color retention, spring greenup, and tissue N were observed. The relative uptake efficiency of 15-N labeled urea is currently being determined through mass spectrometry analysis and will be presented. This research should provide golf course superintendents with science-based guidance regarding best management practices for application of late-fall nitrogen fertilizers on warm-season turf in sub-tropical regions." |
