| Abstract/Contents: | "A completely randomized study was conducted from October 2019 to September 2020 at turf center at University of Kentucky, Lexington, KY on tall fescue (Festuca arundinacea). The study was designed to compare the turf quality under reduced irrigation with robotic or rotary mowers. The required irrigation was calculated based on reference evapotranspiration (ETref) with the location weather, using the PenmanMonteith Equation. Treatments consisted of two types of mowers with different percentage of ETref, which are 1) rotary mowers with 80% ETref replacement (ROT80), 2) robotic mower with 70% ETref replacement (ROB70), and 3) robotic mower with 60% ETref replacement (ROB60). The normalized difference vegetation index (NDVI) was used to determine the density of greenness of turfgrasses, which is strongly associated with turf quality. During the whole growing season, robotic mower plots (ROB60 and ROB70) show no differences (except in April 2020) on NDVI values. Higher values of NDVI were found in robotic plots (0.77) than rotary plots (0.71) during the growing season. Overall, robotic mowers resulted in greater NDVI than rotary plots with reduced irrigation, which was likely caused by a sharper leaf cut from the robotic mowers." |
