USGA Summary Points:Drought susceptible and tolerant cultivars of Kentucky bluegrass and creeping bentgrass were established under a rainout shelter and subjected to well-watered or non-irrigated treatments. Study site soils were characterized for bulk density and a soil water retention properties, which showed a bimodal Seki model to provide the best soil water retention curve fit and a permanent wilt point (-1500kPa) of 7.5% volumetric water content. Canopy responses indicated that despite declines in some easily-measured variables like percent green cover and normalized difference vegetation index, plants may not be experiencing phsyiological stress as measured by photochemical efficiency, FvFm. Cores measuring 25 cm in diameter by 30 cm deep have been collected from each of the plots for further evaluation in a greenhouse during winter 2021. Flaws in the rain shelter design are being corrected to ensure proper, significant dry down in the second year of the experiment.
