| Abstract/Contents: | "Water use and supply in the urban landscape continues to be a concern for many communities throughout the United States. Modern strategies and technologies that help reduce excess supplemental lawn irrigation would be helpful for communities focused on significantly reducing water needs of lawns and landscapes. Species selection is an important factor in reducing overall supplemental irrigation needs. While much of the public prefers an aesthetically pleasing lawn with a consistent green color across the growing season, they are unaware of the irrigation needs for specific species or how factors like mowing height can affect water needs. Species and mowing height factors were studied in greenhouse and field studies to compare the water needs of drought sensitive and drought tolerant Kentucky bluegrass (Poa pratensis: KBG) and tall fescue (Schedonorus arundinaceus: TF) cultivars at two mowing heights (5.0 vs. 8.9 cm). Cultivars of each species were planted in the field and grown to maturity. For the greenhouse study, intact cores were extracted, planted in containers and allowed to acclimate for 90 days. The amount of water required to maintain 60% green color was then measured. Over a 65 day period, the KBG cultivars required the least amount of water, 15.0 and 15.7 cm, at 5.0 and 8.9 cm, respectively. TF required 19.6 and 24.4 cm of water maintained at 5.0 and 8.9 cm, respectively. Mowing height affected water loss for both species. Turf at 5.0 cm lost the least (45.8 g/d-1) compared to turf at 8.9 cm (59.1 g/d-1). The study was repeated in field during the growing season. Green turf cover, total water required, turf quality, and surface temperatures were recorded. Early data reinforces the importance of species and cultivar selection and potentially the role of mowing height for reducing lawn supplemental water needs." |
