Abstract/Contents:Presents a study conducted at the Arkansas Agricultural Research and Extension Center in Fayetteville to "quantify divot resistance for various bermudagrass and zoysiagrass cultivars and species in the field." Details the materials used as five bermudagrass cultivars and seven zoysiagrass cultivars all maintained under typical fairway conditions, including fertilization and irrigation. Describes the methods used as natural divots created by two golfers with single-digit United States Golf Association (USGA) handicaps, with a numerical scale assigned for divot severity and volume measured with sand. Details how a shear tester was also used "to determine divot resistant or lateral shear strength of each of the species and cultivars." Reports that "it is unclear why some cultivars had severe divoting in July as opposed to September or June, but the data suggests there could be seasonal differences in divot severity." Notes that Riviera bermudagrass sustained the largest volume damage, while Cavalier, Diamond, and Zorro zoysiagrass sustained the least. Adds that Cavalier and Diamond zoysiagrass required the highest amount of force to remove a divot, while Patriot and Princess 77 bermudagrass required the least force. Proposes that "cultivars that had high divot resistance tended to have less severe divots, lower volume of soil displaced from divoting and higher Turfgrass Shear Tester readings." Concludes that Cavalier, Diamond, and Zorro zoysiagrass had the highest divot resistance, while Princess 77 and Riviera bermudagrass had the lowest.
