| Abstract/Contents: | "The A and G series of creeping bentgrass reportedly require more intensive management than other cultivars. The effects of verticutting, topdressing, and aeration frequency on turf quality, thatch, and removal of topdressing by mowers were evaluated on four turf types. Plots were seeded on a sand based root zone in 1998 with annual bluegrass (AB), 'A-4', 'G-2', or 'Penncross' creeping bentgrasses. Turf was mowed at 3 mm. Topdressing was applied at either two or four week intervals. Half of the plots topdressed at two week intervals were verticut before topdressing. The amount of sand and peat removed from the first mowing following topdressing was determined by separating the topdressing from the clippings, oven-drying, and weighing. Turf quality and color were rated monthly. Thatch was measured in autumn 1999. 'A-4' resulted in the most topdressing removed, 3.9%, compared to G-2 (3.2%), Penncross (2.7%), and AB (1.5%). Verticutting before topdressing significantly reduced the amount of topdressing picked up by mowing. 'A-4' produced the most thatch (p 0.01), followed by 'G-2', 'Penncross', and AB. 'A-4' and 'G-2' had significantly better color and quality than 'Penncross' or AB. The higher rate of thatch buildup, greater amount of topdressing removal, and greater susceptibility to dollar spot suggest 'G-2' requires less intensive management than 'A-4' while providing superior turf compared to 'Penncross' and AB." |
