Putting Green Bermudagrass Updated and Drone Imaging for Turf Establishment

presented by Ryan Earp, M.S. Graduate Student, Turfgrass Breeding and Physiology

Objective 1: Evaluate several advanced hybrid bermudagrass (Cynadon dactylon x C. transvaalensis) selections for their use on golf course putting greens. 

Objective 2: Evaluate the capability of drone imaging technology to determine establishment of bermudagrass trials.
