Abstract/Contents:"Divots are pieces of the turfgrass canopy removed when golf clubs strike playing surfaces with impact energy that exceeds turfgrass shear strength. Divot resistance and recovery are factors affecting proper selection of turfgrass species (or cultivars of a species) for use on golf course driving range tees. Field research was conducted in Knoxville, TN during summer 2022 evaluating divot resistance and recovery of two hybrid bermudagrasses [C. dactylon x C. transvaalensis, cv. 'Tifway' (TIF) and cv. 'Latitude 36' (L36)] and creeping bentgrass (Agrostis stolonifera, cv. 'L-93XD'). A pendulum apparatus equipped with a weighted pitching wedge was used to create 100 divots on each turfgrass surface on 24 May 2022. Divots were created using an impact energy of 531 J. Divot resistance was quantified via measurements of sand volume required to fill the scar. Divot recovery was evaluated via weekly visual assessments of turfgrass cover within the scar generated in the turfgrass canopy after divot creation. On average L36 hybrid bermudagrass divots measured 341.8 cm3 compared to 342.3 and 750.0 cm3 for TIF and L-93XD, respectively. Divot recovery was fastest for L36 with only 28 days required for complete recovery compared to 44 days for TIF. This research will be repeated in summer 2023 to support golf course superintendents towards optimal management of teeing grounds."
