“…Although there were differences among bermudagrass cultivars across collection dates for clipping yield, they generally all had similar clipping yields. This is similar to previous rankings of divot recovery for bermudagrass cultivars (19).…”

Bermudagrass (Cynodon spp. Rich.) and zoysiagrass (Zoysia spp. Willd.) are two of the most commonly used turfgrass species on golf course fairways and tees in the southern United States. However, there are few reports directly comparing commonly used cultivars of bermudagrass to commonly used cultivars of zoysiagrass. The objectives of this research were to quantify the clipping yield, percent ball exposed (ball lie), and to identify the scalping tendency for five bermudagrass and seven zoysiagrass cultivars grown in Fayetteville, AR. The cultivars generally producing the lowest clipping yields were ‘Patriot’ bermudagrass and ‘Meyer’ zoysiagrass, while ‘Tifway’ bermudagrass and ‘Palisades’ zoysiagrass generally had the highest clipping yields. On most collection dates, Cynodon spp. yielded more clippings than Zoysia spp. Patriot bermudagrass had the highest scalping tendency across the two years of this study. The cultivars Patriot, ‘Riviera,’ ‘Tifsport,’ and Tifway bermudagrass as well as Meyer and Diamond zoysiagrass had the best ball lie in unmown (five days after mowing) conditions, while Palisades zoysiagrass had the poorest ball lie in unmown conditions. Ball lie was similar for all cultivars immediately following mowing. These studies identified cultivars of bermudagrass and zoysiagrass that have improved clipping yields, scalping tendencies, and golf ball lie.

“…Because research has not been conducted to compare divot recovery of bermudagrass and zoysiagrass in the same experiment, discussion comparing our findings with previous work is limited to tests evaluating single species. Similar to these findings, Karcher et al (4,5) observed cultivar performance differences across collection dates in divot recovery for bermudagrass and zoysiagrass. For divot recovery of bermudagrass in 2003, Karcher et al (4) found that Princess 77, Patriot, and Riviera had faster divot recoveries than Tifsport and Tifway, which is similar to findings of this study on 29 June 2009.…”

“…El Toro had the fastest divot recovery in one year of the study, but had a relatively slower divot recovery in another year. Although bermudagrass and zoysiagrass were evaluated in separate experimental areas by Karcher et al (4,5), their data suggest that the recuperative capacity of these two species may not be as different as previously reported (1,10). For example, in 2004 Karcher et al (4) reported that Riviera bermudagrass required 4.6 days to reach 50% recovery, while in 2004 Karcher et al (5) reported that Palisades zoysiagrass required 4.2 days to reach 50% recovery.…”

It has also been reported that zoysiagrass cultivars can differ greatly in growth rate and establishment rate (6), suggesting that some zoysiagrass cultivars may also have divot recovery similar to specific bermudagrass cultivars.…”

“…Images were processed in Adobe Photoshop CS4 (Adobe Systems, San Jose, CA) prior to being analyzed for percent green turf cover using SigmaScan Pro 5 software (Systat Software Inc., Richmond, CA) (8) using a divot recovery macro. Similar to Karcher et al (4), non‐linear regression analysis was used to differentiate days to 50% recovery from injury using GraphPad Prism (GraphPad Software v. 5.0, San Diego, CA). An exponential one‐phase model was used to estimate the slope for each cultivar using the following equation:

recovery (%) = 1 - {normale}^{(- K * days after injury)} .

Mean times to reach 50% recovery for each cultivar were separated using 95% confidence intervals determined for the predicted slope (K) values of cultivar mean recovery time using the GraphPad Prism statistical package.…”

Golfers commonly remove turf and soil when swinging a golf club causing a divot in the turf. Divot recovery is an important factor that should be considered when selecting a species or cultivar for use on golf course tees or fairways. There are few reports directly comparing the divot recovery among bermudagrass (Cynodon spp. Rich.) and zoysiagrass (Zoysia spp. Willd.) cultivars. Therefore, the objective of this experiment was to quantify divot recovery of several bermudagrass and zoysiagrass cultivars in a combined field experiment. Divot recovery was evaluated on four collection dates for five cultivars of bermudagrass and seven cultivars of zoysiagrass. Cultivars generally with the fastest time to 50% recovery were ‘Princess 77’ and ‘Riviera’ bermudagrass and ‘Palisades’ zoysiagrass. Generally, the cultivars with the slowest time to 50% recovery were ‘Meyer’ and ‘Zenith’ zoysiagrass. Additionally, ‘Tifway’ bermudagrass had similar divot recovery times to ‘El Toro’ and Palisades zoysiagrass. These results demonstrate that differences and similarities exist among bermudagrass and zoysiagrass cultivars for divot recovery, and golf course superintendents can use this information to better select cultivars that could improve surface playing conditions.

To extend golf play in early summer or hasten athletic field preparation in late summer, turf managers often desire to allow perennial ryegrass (Lolium perenne L.) to persist and compete with overseeded bermudagrass (Cynodon dactylon L. Pers.) or hybrid bermudagrass (Cynodon dactylon × C. transvaalensis Burtt Davy) during optimal growing conditions. Understanding how competition‐free growing degree‐days (CFGDD) influence bermudagrass total nonstructural carbohydrates (TNC), biomass, and visual green cover may aid in turf‐use scheduling. Twenty‐four weekly treatments of foramsulfuron eliminated perennial ryegrass competition in replicate plots and allowed assessment of competition‐free bermudagrass coverage, biomass, and TNC as related to cumulative heat and light units. Results from this study indicate that bermudagrass coverage is a function of cumulative CFGDD and competition‐free daily light integral (CFDLI) but is dependent on locations or years where cultivars or seasonal legacy are variable. At three locations, ‘Patriot’ and ‘Midiron’ hybrid bermudagrass and ‘Riviera’ bermudagrass required 603, 709, and 959 CFGDD and 2,447, 3,271, and 4,556 mol m–2 CFDLI to reach 97% coverage, respectively. Trends of TNC per unit area, however, continued to increase after full coverage was achieved and up to the point at which no more heat or light units were accumulated in fall. Absence of a clear asymptote in the trends suggests that heat or light units that were seasonally accumulated in Blacksburg, VA, were insufficient to achieve maximum bermudagrass carbohydrate reserves before winter dormancy.
