Abstract/Contents:"Urban water supply is critically important in a rapidly growing population. This research highlights the importance of water use efficiency in urban turf landscapes. A chronic drought stress field trial was conducted in Lubbock, TX. Common turfgrass species grown in the transition zone were chosen: buffalograss, zoysiagrass, and bermudagrass. Supplemental drip irrigation was applied six days per week at 0, 0.8, 1.3, 2.1, and 2.9 cm per week. The plots were arranged in a randomized complete block design, and further divided into subplots with a mowing treatment of 5.1 cm and 8.9 cm as the low and high mowing regime, respectively. A total of 4 replications of each species, irrigation, and mowing treatment was present in the field. Variations in volumetric water content were confirmed with TDR measurements. Visual turf quality and leaf firing were obtained once per week along with digital image analysis (DIA) and NDVI to assess drought responses of species. Canopy temperature measurements provided a physiological response of drought to these turf species. Bermudagrass had highest mean percent green cover and NDVI when combining all irrigation levels. Summer heat in the field negatively impacted tall fescue performance the most, regardless of irrigation level. Special emphasis was also given to the change of quality measurements, both visual and calculated from DIA software, as quality is the goal of the research under limited irrigation. This research demonstrates the drought tolerance capabilities of turf species commonly used in residential landscapes within the transition zone and the physiological response of the species to chronic drought stress. Research presented will focus primarily on the objective data such as NDVI measurements and the digital image analysis of percent green cover differences in treatments."
