| Abstract/Contents: | A study was undertaken in 1987, 1988 and 1989 to measure the evapotranspiration (ET) rates of the turfgrass species: annual bluegrass, Kentucky bluegrass, perennial ryegrass, creeping red fescue (Festuca rubra spp. rubra L.), tall fescue, and colonial bentgrass (Agrostis tenuis Sibth.). Cylindrical PVC weighing lysimeters, 24.8 X 30.5 cm in size, were used to assess ET. The lysimeters were placed in below-ground silos in a turf sod and once daily lifted from their silos and weighed within 2 g (20,000:1 sensitivity) for water loss. Measurements were made during July to September in each year. Species ET declined in the order perennial ryegrass > annual bluegrass > tall fescue > creeping fescue > Kentucky bluegrass > colonial bluegrass, but no difference in average daily ET could be detected among perennial ryegrass, annual bluegrass, tall fescue, or creeping fescue. Grasses irrigated at 60% deficit ET used 9.3% less water, but turf quality of annual bluegrass, tall fescue, and colonial bentgrass declined significantly when managed at this level. Averaged on a weekly basis, turfgrasses used 1.6 cm (.63 in.) to 3.2 cm (1.26 in.) of water weekly. The highest water use rate was 57% of the high expected rate in dry, southwestern climates during peak demand periods. Turfgrass used 40 to 50% less water at Puyallup than could be expected of turf use in the Southwestern U.S. during peak demand periods and 60 to 70% of the water that is commonly expected of turf in the intermountain areas on an average daily basis. On a weekly basis, this demand was averaged about 0.75 inch but was as high as 1.25 inch during the peak demand periods with the higher water use rates experienced with tall fescue. |
