| Abstract/Contents: | "St. Augustinegrass (Stenotaphrum secundatum) is adapted to warm subtropical regions and is the most widely produced and utilized species for sod and lawns in Florida. Fertilization is an important component of lawn management; however, there are environmental concerns associated with the application of fertilizers. Several ordinances exist throughout Florida dictating the timing of fertilization. Knowledge regarding the timing of applications, amounts and the responses of differing cultivars is critical for obtaining adequate turf quality with minimal application of fertilizers. The objective of this study was to evaluate the effects of four fertilization regimens (UF-IFAS recommendations, summer blackout, national retail product recommendations, and no added fertility) and two mowing heights (5.0 and 8.75 cm) on three St. Augustinegrass cultivars (CitraBlue, Floratam, and Palmetto). The experimental design was a RCBD with a strip-split plot design and three replications with cultivars as main plots, mowing heights as strips and fertility treatments as sub-sub-plots. Chlorophyll levels (SPAD units) of leaves and visual turfgrass quality, color, and density ratings were measured monthly from Sep 2018 to Apr 2020 and seasonal averages calculated (spring = Jan to Apr; summer = May to Aug; fall = Sep to Dec). There were significant differences in turfgrass quality, color, density, and SPAD units between cultivars and fertilizer treatments for each season but no significant interactions. No added fertility showed lower performance; differences between the three regimens were minimal. CitraBlue generally showed superior turfgrasss quality ratings across seasons." |
