Response and Recovery Characteristics of Kentucky Bluegrass Cultivars to Extended Drought

“…Withholding irrigation until the 75% green stage is reached could save a significant amount of water in all bluegrasses, but particularly in those that retain green longer. In a previous study on these same plots, where irrigation was withheld until bluegrasses exhibited symptoms of drought stress, water savings were as high as 54% during summer months in cultivars that succumbed slower to drought stress (Lewis et al, 2012).…”

“…1 and Fig. 2); these cultivars have previously performed well under reduced irrigation in Kansas (Lewis et al, 2012) and would be good choices for those interested in growing Kentucky bluegrass under such conditions. The performance of the two hybrid bluegrasses (Thermal Blue Blaze and Longhorn) was similar to the other KBG cultivars during the dry downs and recoveries, which is comparable to results from other research (Bremer et al, 2006;Su et al, 2007Su et al, , 2008Su et al, , 2009Richardson et al, 2008Richardson et al, , 2009).…”

“…Wide ranges in drought tolerance and water use among KBG cultivars undoubtedly contribute to its adaptability (Shearman, 1986; Ebdon and Petrovic, 1998; Richardson et. al., 2009; Merewitz et al, 2010; Lewis et al, 2012).…”

“…The rainout shelter rested north of the plot area but automatically covered the plots as precipitation began, and retracted 1 h after cessation of rainfall. Additional details about plot establishment and cultivar selection can be found in Lewis et al (2012).…”

Minimal Water Requirements of Cool-Season Turfgrasses for Survival and Recovery After Prolonged Drought

“…The loss of turfgrass during severe droughts may result in unsatisfactory visual appearance and significant reestablishment and human labor costs. Previous studies have indicated that limited water applications during droughts may mitigate the severity of drought stress and improve Kansas State University Agricultural Experiment Station and Cooperative Extension Service the ability of turfgrass to recover upon rewatering (Lewis et al, 2012;Goldsby et al, 2015). This indicates a possible strategy to achieve a balance between water conservation and turfgrass survival through droughty periods.…”
