Abstract/Contents:"Surface hardness can increase on highly trafficked sports fields where turf cover is reduced. Traffic tolerant Kentucky bluegrass (Poa pratensis L.) cultivars can be established on recreational sites to provide more uniform surfaces. The objective of this abstract is to report on surface hardness responses of entries in the 2017 National Turfgrass Evaluation Program (NTEP) Kentucky Bluegrass Test subjected to traffic stress. Three replications of 89 entries were seeded in September 2017 on a loam in North Brunswick, NJ. Traffic was applied in a strip across half of each plot using a combination of the Rutgers Wear Simulator and Cady Traffic Simulator during 2018 to 2022; the other half of each plot did not receive traffic. A Clegg Impact Turf Tester equipped with a 2.25 kg hammer was used to assess the surface hardness (Gmax) of no traffic and traffic plots on 9 June and 3 August 2022. Data were analyzed as a 2 (no traffic and traffic) x 89 (entries) factorial strip-plot design. Greater surface hardness (higher Gmax) was measured on trafficked Kentucky bluegrass plots compared to no traffic plots on 9 June and 3 August 2022. A significant entry main effect on surface hardness occurred on 9 June 2022; 30 entries had the lowest Gmax. A significant traffic x entry interaction on 3 August 2022 indicated that traffic did not affect the surface hardness of Paloma. Fifty-four entries had the lowest surface hardness under traffic stress on 3 August 2022 including the following commercially available cultivars: Prosperity, Blue Gem, Jersey, Barvette HGT, Finish Line, After Midnight, Bombay, Acoustic, Paloma, Yellowstone, New Moon, Barserati, Twilight, Syrah, Babe, United, Blue Devil, Super Moon, Electric, Aviator II, Blue Magic, Blue Knight, Midnight, and Skye. Correlations (Pearson product movement) of turf cover (visually rated) and surface hardness revealed an inverse relationship."
