Effects of Mowing and Rolling Frequency, PrimoMaxx, and Roller Weight on Annual BluegrassPutting Green Speed

摘要

This study was conducted on an annual bluegrass (Poa annua L.) putting greenand examined the effects on ball roll distance (BRD) from five mowing and rollingfrequency regimes using both a light and heavy roller with and without PrimoMaxx. Treatments included: (i) mow daily with no rolling; (ii) mow daily + roll M,W, F; (iii) mow daily + roll daily; (iv) mow M, W, F, Sa + roll daily; and (v)alternate mowing and rolling daily. For six weeks during the summers of 2009 and2010, ball roll distances were measured in the morning and afternoon, Mondaythrough Friday. BRD decreased an average of 0.5 ft from the morning to theafternoon. The heavy roller significantly increased BRD in 2009 by 0.4 ft or less,but not in 2010. Primo Maxx increased BRD an average of 0.5 ft in 2010, but notin 2009. Mowing + rolling daily produced the longest BRD followed by mow daily +roll M, W, F and mow M, W, F, Sa + roll every day which was 0.5 ft less. Mow dailywith no rolling and alternate mowing and rolling daily had the shortest BRDaveraging 1.2 ft less than mowing and rolling daily.
