| Abstract/Contents: | "High quality lawns require consistent mowing, feeding, and water supplied as either natural precipitation or supplemental irrigation. Water scarcity concerns, even in cool-humid climates, have spurred interest in refining lawn water conservation approaches, like supplemental irrigation programs. The established guideline for lawn water requirements suggests providing 25-37.5 mm wk-1, typically applied programmatically on a Monday-Wednesday-Friday (M-W-F) schedule in the absence of rainfall. During severe drought, excessive outdoor water use can strain local water systems, and policy-makers often mandate applications of only once or twice wk-1. Information regarding the effects of lawn irrigation frequency on traditional cool-season lawn grasses is limited. A two-year field study was conducted to study three supplemental irrigation programs: 32 mm wk-1 either three times (M-W-F) or twice (M-Th) and 80% of accumulated potential evapotranspiration (pET) applied (M-W-F) and compared to a rainfall only control over a 75 day summer period. These programs were applied to five lawn grass sub-plots: two seeded Kentucky bluegrasses (KBG), a turf-type tall fescue blend, a 50:50 KBG:perennial ryegrass mixture and sodded KBG. Turf responses were measured as weekly digital green color, volumetric soil water content (0-7.6 cm), visual quality and the area under the turf quality curve (AUTQC) was calculated. Rainfall in year one and two measured 174.6 mm and 350.4 mm, respectively, which affected all measured parameters. The area under the turf quality curve (AUTQC) was lowest for the rainfall control (338.8 and 424.9) and highest for the 80% ET treatment (462.4 and 480.6) in year one and two respectively. Supplemental irrigation aided all species, yet under rainfall-only conditions, tall fescue blend, KBG "Diva", and sodded KBG showed greater drought resilience with sustained green cover in year one, while KBG "Desert Moon" and tall fescue blend performed better in year two." |
