| Abstract/Contents: | "Kentucky bluegrass (Poa pratensis L.) and tall fescue (Festuca arundinacea Schreber) are often established on highly used sports fields and individual cultivars may differ greatly in response to traffic stresses. Evaluation of cultivar performance under traffic stresses during individual seasons (spring, summer, and fall) is needed since sports field use is often season-specific. Entries comprising the 2005 National Turfgrass Evaluation Program (NTEP) Kentucky bluegrass test were seeded in September 2005 with the objective of determining the seasonal wear tolerance and recovery among Kentucky bluegrass cultivars and experimental selections. Entries comprising the 2006 NTEP Tall fescue test were seeded in September 2006 to assess the seasonal wear and compaction (traffic) tolerance and recovery of tall fescue cultivars and experimental selections. Both trials were established on a sandy loam in North Brunswick, NJ. The experimental design for both trials was a randomized complete block with three replications. Wear was applied using a modified Sweepster that permitted control of both operating speed (2.5 mph) and paddle rpm (250 rpm). Eighteen (18) wear passes were applied to the Kentucky bluegrass trial over three (3) days in summer 2007 (6 passes on 25 July; 6 passes on 26 July; and 6 passes on 27 July); visual ratings of the fullness of live cover were taken to assess wear tolerance after 6, 12, and 18 passes of the wear simulator and recovery at 10, 19, and 56 days after wear (DAW). Wear was previously applied to this test in October 2006. The tall fescue trial was subjected to 24 passes with the wear simulator applied over three (3) days in fall 2007 (8 passes on 2 October; 8 passes on 3 October 2007; and 8 passes on 4 October). Visual ratings of fullness of live cover were taken to assess wear tolerance after 8, 16, and 24 passes of the wear simulator. After wear simlation, ten (10) passes of a 1264-kg vibratory pavement roller were applied on 10 October to compact the soil. Visual ratings of the fullness of turfgrass cover were taken on 10 October (5 DAW) and 1 November (22 days after compaction [DAC]). Kentucky bluegrass entries that had the greatest fullness of turfgrass cover after 18 passes of the wear simulator in July 2007 were 'Harmonie', CP 76-9068, CPP 822, CPP 821, 'Julia', NA-3257 and 'Bariris.' The entries, DLF 76-9075, PSG 366, A95-410 and RAD-504, were among cultivars that had the lowest fullness of cover in both October 2006 and July 2007. Fullness of cover ratings indicated that more than 2 dozen tall fescue entries maintained good to excellent cover at 0 DAW and fair cover 22 DAC. The commercially available entries in this group included 'Rebel IV', 'Titanium', 'Firenza', 'Hemi', 'Turbo', 'Bullseye', 'Rembrandt', 'Padre' and 'Biltmore.' Results of previous traffic tolerance research reported that Padre was among the top performing tall fescue cultivars and 2001 NTEP tall fescue trial evaluated under simulated wear and compaction during 2002 and 2003 in North Brunswick, NJ. Among the tall fescue entries with the lowest fullness of turf canopy at 22 DAC were 'Hunter' and 'Ky-31' aw well as two commercially-available blends that were not part of the 2006 NTEP tall fescue test. These blends were: Pennington's Best ('Forte' [33%], 'Prospect' [33%] and 'Signia' [33%]); and Water Saver ('Labarinth' (RTF) tall fescue [34%], 'Aztec II' [24%], 'Focus' [20%], and 'Rendition' [20%]). Various Kentucky bluegrass and tall fescue cultivars have demonstrated excellent wear and wear and compaction tolerance (fullness of turf canopy) after simulated traffic stresses were applied in 2007. Wear will be applied to the Kentucky bluegrass test in spring 2008; the tall fescue test will be subjected to wear and compaction in summer 2008. Data generated from these trials will assist turfgrass managers in selecting cool season turfgrasses for highly used sports fields and other recreational areas." |
