Abstract/Contents:"The success of irrigation rates and frequencies depends heavily on environmental conditions and turfgrass selection. Irrigation research on cool-season turfgrass in the coastal region of the Pacific Northwest, a cool-humid climate which receives minimal precipitation in the summer months, is lacking. Therefore, the goal of this research was to determine the optimal watering frequency and rate that provides acceptable perennial ryegrass turfgrass maintained at 2.0 inches throughout the dry summer months in Western Oregon. Experimental design was a 2x4x5 factorial in a randomized complete block design with four replications. Factors included year (2016 and 2017), irrigation frequency (2, 4, 8, and 16 applications per month), and irrigation rate (2.0, 2.5, 3.0, 3.5, and 4.0 inches per month) applied from July 1 to September 1. Irrigation applied at a rate of 3.0 inches per month (0.75 inches per week) from July to September improved perennial ryegrass turf quality and percent green cover similar to that of over-irrigation (3.5 inches per month or greater). Eight irrigation applications per month (twice a week) will result in sustainable perennial ryegrass turf quality during the summer months, while sixteen applications per month (four times a week) will provide the greatest perennial ryegrass turf quality. Replacing 45 to 49% evapotranspiration is adequate to maintain acceptable turfgrass quality in this environmental zone."
