Abstract/Contents:"Many cultivars of Kentucky bluegrass (Poa pratensis L.) have been developed since the release of the first turf-type selection 'Merion" in 1947. Kentucky bluegrass is often established on highly used sports fields and individual cultivars may differ greatly in their responses to traffic. Cultivars of Kentucky bluegrass were seeded in 2002 and a study was initiated in the spring 2004 with the folllowing objectives: 1) Identify the relative importance of specific traffic stresses (wear and/or compaction) to performance of Kentucky bluegrass cultivars; and 2) Determine seasonal wear tolerance and recovery differences among Kentucky bluegrass cultivars. The first objective will refine our understanding of damage caused by traffic, enable turf managers to prioritize cultural practices that target the most important stress, and assist breeders in developing screening procedures for germplasm selection. The second objective is important because many better performing Kentucky bluegrass cultivars tested under traffic during summer months have strong winter dormancy. Thus, evaluation of cultivar performance under traffic during spring and fall is also needed since these are the seasons when majority of traffic (i.e., soccer, footbal, and lacrosse) occurs on sports fields. To satisfy the first objective, simulated wear, compaction, and combined wear and compaction was applied to Kentucky bluegrass cultivars from March to November 2004. To fulfill the second objective, wear was applied to the Kentucky bluegrass cultivars as part of separate spring (March-May), summer (July-August), and fall (October-November) treatments in 2004. All plots were visually rated for turfgrass performance and recovery throughout the test period. Turfgrass performance was assessed utilizing a 1-9 scale (9=best performance) and by visually determining fullness of turfgrass cover (0-100%; 0%= complete defoliation of turfgrass cover; 100%=full turfgrass canopy). Initial data from this study suggests that the combined stresses of wear and compactions contributed to lower turfgrass performance compared to either wear and compaction alone. Examining wear and compaction individually, Kentucky bluegrass cultivar performance was lower under wear alone compared to compaction applied alone. Data collected from individual seasonal applications of wear appears to indicate that the performance level of some cultivars when subjected to wear is affected by the season in which wear is applied. Continued data collection will identify specific traffic stresses which most affect turfgrass performance and allow for season-specific Kentucky bluegrass cultivar recommendations."
