| Abstract/Contents: | "Turfgrasses provide many functional, environmental, and aesthetic benefits, but many perceive lawns as only a visual benefit that requires significant water inputs. The use of drought resistant grasses and deficit irrigation practices can reduce water use without sacrificing lawn quality, but a lawns irrigation requirement may vary by soil texture or irrigation frequency. The objective of this study was to evaluate the effects of cultivar selection, soil texture, irrigation frequency and volume on the quality and water use of Kentucky bluegrass (Poa pratensis L.) lawn turf. Two Kentucky bluegrass cultivars (Mallard and Geronimo), two soil textures (silt loam and loamy sand), two irrigation frequencies (1 and 3x weekly), and two irrigation volumes (40 and 80% reference evapotranspiration) were evaluated in a complete factorial field lysimeter experiment. Lysimeters were weighed prior to irrigation, and actual evapotranspiration was calculated between successive lysimeter weighing events. Lawn quality was determined by evaluating green turf coverage weekly. Lysimeters replacing 80% reference evapotranspiration 3x weekly resulted in greater coverage in September, whereas irrigation frequency affected coverage at 40% reference evapotranspiration replacement on two dates in September. Lysimeters replacing 80% reference evapotranspiration used 1.8x more water than 40% reference evapotranspiration in late August and September. Water use was significantly affected by soil texture, with lysimeters containing silt loam and loamy sand using 2.4 and 2.3 cm per week, respectively." |
