Abstract/Contents:"Lawns require regular mowing, feeding and water (natural precipitation and/or supplemental irrigation) to persist. Water scarcity concerns have led to heightened interest in improved lawn water conservation strategies. The "rule of thumb" regarding lawn water needs is to supply 25-37.5 mm growing wk-1 often applied on a programmatic Mon.-Wed.-Fri. schedule. During acute drought frequent irrigation events may strain municipal/community water networks resulting in applications being limited to once or twice weekly. Little information exists regarding the effect of lawn irrigation frequency strategies. Two field studies were conducted on a mature Kentucky bluegrass (Poa pratensis L.) turf located under a fixed-roof rainout structure. In year one, six programs which varied by quantity and application frequency were compared to a non-irrigated control for 48 days. The programs were: 25 mm total wk-1 applied 3 times weekly (M-W-F) or twice weekly (M and F), 17 mm total wk-1 twice weekly (M and F), 12 mm total wk-1 once weekly and twice weekly at 60 or 80% accumulated evapotranspiration (ET). In year two, seven programs were evaluated: 32 mm total wk-1 applied 3 times weekly, twice weekly, once weekly or every-other-day, 24 mm total wk-1 applied either 3 times weekly or twice weekly and 80% ET for 60 days. Turf response was determined by visual quality ratings, digital green color and volumetric soil water content. Generally, irrigation applied two or three times per week resulted in the most consistent appearance but once weekly also provided a reasonable appearance for most of each study period."
