| Abstract/Contents: | "The density and aggressive creeping growth habit of bermudagrass (Cynodon ssp.) makes it a desirable sports turf surface and its use continues to expand in the transition zone of the United States. However, when combining possible constraints in winter hardiness, a winter dormancy period of at least 5 months in the transition zone, and intensive traffic of a fall sports season (primarily American football), there are likely limitations in long-term persistence and performance of some bermudagrass cultivars for transition zone athletic fields. The defunct 2007 National Turfgrass Evaluation Program bermudagrass trial in Blacksburg, VA was used to evaluate 31 bermudagrass cultivars under simulated fall football traffic conditions. A modified Brinkman traffic machine was used to simulate an equivalent of 3 football games per week for 10 consecutive weeks during the fall seasons of 2013 and 2014. The plots were periodically evaluated in the fall by both visual (estimated percent bare ground in the trafficked plots) and mechanical (both Normalized Difference Vegetation Index, NDVI and Ratio Vegetation Index, RVI) methods in order to quantify overall fall traffic tolerance, turf health, and plot density. The plots were also visually evaluated in the spring (estimated percent bermudagrass greening) and with NDVI/RVI measurements. There were significant cultivar main effects for fall visual ratings on percent bare ground and spring visual ratings for percent bermudagrass greening. Latitude 36, Tifway, Northbridge, Yukon, SWI-1057, and Premier Pro were in the highest statistical category for wear tolerance ratings (i.e., the lowest percent bare ground values) across the fall rating periods and Yukon, Latitude 36, Northbridge, and Patriot had the highest spring greening percentages across the spring ratings. RVI measurements generally correlated with the visual ratings and were deemed superior to NDVI measurements in this trial due to a more accurate bare ground assessment in the trafficked plots." |
