USGA Summary Points: | A second year of data was collected on drought susceptible and tolerant cultivars of Kentucky bluegrass and creeping bentgrass that were under a rainout shelter and subjected to well-watered or non-irrigated treatments. Cores of those plots were further evaluated in a greenhouse trial. Plots of each susceptible cultivar were compared under differing threshold-based irrigation treatments (Phase II). Canopy responses of creeping bentgrass field plots again indicated that despite declines in some easily-measured variables like percent green cover and normalized difference vegetation index, plants may not be experiencing physiological stress as measured by photochemical efficiency, FvFm. This relationship was not as consistent for Kentucky bluegrass during Year 2 or for either species in the greenhouse evaluation. Phase II study site soils were characterized for bulk density and soil water retention properties which showed a plant available water range (-1500 to -10 kPa) of 4.37 to 43.66% volumetric water content. Creeping bentgrass plots irrigated at higher moisture thresholds used significantly more water and remained significantly softer and greener; however, a moisture threshold of 45% plant available water reduced water use significantly while maintaining similar final firmness and canopy cover. |
