Abstract/Contents:"With a rapidly expanding population and an epic geography dictating Colorado as a head water state, the topics of water use and conservation are ever present to the citizens of Colorado. Selecting species and cultivars that use less water while maintaining acceptable quality will mitigate irrigation demands. Field research is conducted to: 1) compare turfgrass quality and growth of 15 Kentucky bluegrass lines, 19 tall fescue lines, 1 perennial ryegrass line under different irrigation treatments [0.80 reference ET (ETo), 0.60 ETo, and 0.40 ETo] applied twice weekly, 2) determine relative drought resistance of different entries, and 3) document water quantity required for each entry to maintain acceptable and desirable turf quality and thereby assessing their water use efficiency. A full set of replicated study plots, i.e. 9 blocks, with each block consisting of 35 cool season turfgrass lines were established in 2017 with field study conducted in 2018 and 2019. Data were collected on turf quality, water input, green coverage, drought stress symptoms and survival. A light-controlled digital imaging tool and image analyzing software were used to objectively derive turf quality parameters. Research and data collection for the 2018 season showed that en masse, tall fescue lines showed higher overall quality than Kentucky bluegrass cultivars in all 3 reference ETo treatments while Kentucky bluegrass cultivars showed increased ability to recover from drought. These initial results could be due to tall fescues adapted ability to excavate deeply within the soil profile in search for water while Kentucky bluegrass adaptively reverts to dormancy in the face of drought stress. Successive yearly research regimes and data collection are necessary and will be conducted throughout 2019 to determine the amount of water needed to maintain acceptable quality for each included turfgrass cultivar."
