Abstract/Contents:"Hollow tine aerification and sand topdressing have been used on golf course putting greens for decades to manage organic matter accumulation, improve infiltration, and maintain firm playing conditions. In more recent years, superintendents and researchers have been exploring solid tine aerification and topdressing without aerification. Despite recent trends, aerification and topdressing research on annual bluegrass putting greens in the Pacific Northwest, where 12 months of growth can be expected, and long-term research on putting greens, is minimal. A 5-year field trial was initiated in May 2020 at the OSU Lewis-Brown Horticulture Farm in Corvallis, OR. Experimental design for the trial is a randomized complete block design with four replications. Treatments are arranged in a 2 x 7 factorial, with two sand topdressing rates (50 and 100 lbs 1000 ft-2) and 7 cultivation treatments [hollow tine (HT) spring, fall, and both spring and fall; solid tine (ST) spring, fall, and both spring and fall; and a non-cultivated plot that received sand topdressing]. A non-treated control (no cultivation, no sand topdressing) was also included in the analysis. The main effect of cultivation treatment influenced turf quality (TQ) in Aug, Sept, Oct, and Nov of 2020, with spring cultivation treatments (HT spring, HT spring & fall, ST spring, ST spring & fall) generally resulting in greater TQ rating than fall cultivation treatments and topdressing only plot. Orthogonal contrast between spring cultivation treatments and all other treatments indicate spring cultivation had greater infiltration than plots that didnt receive spring cultivation. Neither main effect of topdressing rate or cultivation treatment had an effect on yellow patch severity in the fall of 2020; however, all combinations of topdressing rate and cultivation treatments reduced yellow patch severity compared to the non-treated control."
