| Abstract/Contents: | "With water for turfgrass irrigation becoming increasingly scarce, researchers at Kansas State University investigated 28 Kentucky bluegrass (Poa pratensis L.) cultivars and two hybrids (P. arachnifera Torr. x P. pratensis) for their potential to maintain acceptable quality with less water using wilt-based irrigation. Irrigation was applied when >=50% of a plot exhibited wilt. Results include: Seasonal irrigation ranged from 9.2-17.7 inches over approximately 3.5 months (0.6-1.2 inches/week) among cultivars. Less water was applied to cultivars in Compact America and Mid-Atlantic phenotypic groups and the most to cultivars in the Common group. Days to wilt between irrigations ranged from 6.4-13.1 days among cultivars but was greatest in Compact America and Mid-Atlantic types. This provides estimates of irrigation frequency required to maintain these bluegrass cultivars at levels similar to this study, at least in the transition zone. Visual quality declined below "minimally acceptable" in all cultivars. The rate of decline varied from 8.1 to 44.8 days but was fastest in Common (10.4 days). Overall, visual quality averaged slightly below acceptable, which may be appropriate for low-maintenance roughs. Cultivars in Compact America and Mid-Atlantic groups likely have the greatest potential for maintaining acceptable visual quality with less water." |
