| Abstract/Contents: | "Deep, infrequent irrigation rather than light and frequent irrigation is encouraged by numerous municipalities as a strategy to conserve water used for turfgrass. However, limited information is available on the effectiveness of such practices in an arid climate. A study was conducted at New Mexico State University to compare the impact of 3 irrigation frequencies, daily, every other day and twice a week, on performance of 2 varieties of tall fescue (TF) (Festuca arundinacea L.), Kentucky bluegrass (KB) (Poa pratensis L.) and perennial ryegrass (PR) (Lolium perenne L.). Turfgrasses were maintained at 5cm height and irrigation was applied at 70% of reference evapotranspiration with the total weekly amount equal for all treatments. Turfgrass performance parameters were measured monthly and root samples were collected twice per year (April and October). When averaged over the growing season, turfgrass quality and cover was highest when irrigated daily (5.5 and 72%) compared to every other day (5.1 and 72%) and twice a week (4.2 and 54%). Tall fescue and KB varieties had higher normalized difference vegetation indices (0.668 and 0.679 respectively) compared to PR (0.618). Daily irrigation resulted in higher root weight density and root length density at 0 to 5 cm depths (5.1 µg/cm3 and 48.3 cm cm3) compared to the biweekly irrigation treatment (4.2 µg/cm3 and 41.0 cm cm3). Both KB varieties had higher root length density (averaged over depth and sampling dates) compared to TF and PR but there were no differences in root weight density. Moreover, KB had a lower root diameter compared to the other two grasses. We concluded that deep and infrequent irrigation (twice per week) impacted turfgrass quality negatively compared to light and frequent (daily) watering and did not promote deep rooting." |
