| Abstract/Contents: | "Water restrictions on irrigation are rarely science based and may cause irreversible damage to turfgrass or inadvertently waste water. Our objectives were to evaluate effects of minimum water applications to Meyer Japanese lawngrass (Zoysia japonica Steud.) on (a) canopy performance during prolonged drought and (b) survival and recovery thereafter. Meyer was watered weekly with 0-30% reference evapotranspiration (ETo) replacement for ≥56 d in two consecutive summers under a rainout shelter near Manhattan, KS. Soil moisture and canopy performance (normalized difference vegetation index [NDVI], percentage green cover [PGC], and turfgrass quality) were measured weekly. Results indicated 20-30% ETo slowed the decline in canopy performance compared with no water inputs. Irrigation at 30% ETo maintained Meyer at >75% PGC throughout the first year, but even Meyer at 0 and 5% ETo recovered after full irrigation resumed. In the second year, 30% ETo maintained Meyer at >25% PGC throughout the drought and recovered thereafter, but plots with 0 and 5% ETo only recovered to 30-42% PGC after 50 d of full irrigation. Depending on the weather, reducing irrigation from the recommended 60% ETo for warm-season turfgrasses to 30% ETo saved 9-11 cm of water; further reductions to 20% ETo saved another 3-4 cm during the droughts of ≥56 d with insignificant additional PGC reductions (<18%). Water restrictions during severe droughts, such as limiting weekly irrigation of Meyer Japanese lawngrass to 20-30% ETo, could reduce turfgrass damage and conserve water." |
