Potassium, which reduces turfgrass tolerance to environmental stresses when deficient, is often applied at rates equal to or greater than N in an attempt to increase its efficacy. Drought resistance for recently established 'TifDwarf' (TD) and 'TifEagle' (TE) bermudagrasses [Cynodon dactylon (L.) Pers. × C. transvaalensis Burt Davy], 'SeaDwarf' (SD) seashore paspalum (Paspalum vaginatum Swartz), and 'PristineFlora' (PF) zoysiagrass [Zoysia japonica Stued. by Zoysia tenuifolia (L.) Merr.] was evaluated under varied irrigation and K levels on a U.S. Golf Association (USGA)-specified research green. Irrigation treatments were applied in the spring and fall of 2009 and spring 2010, and included 25, 50, and 100% of potential evapotranspiration (ETo), as calculated using the Blaney-Criddle equation. Nitrogen at 4.9 g m-2 30 d-1 and K (as KCl) in 1N:1K, 1N:2K, 1N:3K, and 1N:4K fertilization ratios were applied at the beginning of each experiment. All cultivars had objectionable wilting (>10%) at 25% ETo in 2009, although PF and SD had least in the fall. In 2010 PF and SD did not exhibit objectionable wilting at any irrigation level. At 50% ETo, TD and TE wilted objectionably in all experiments, as did PF in the fall of 2009. In 2010, the bermudagrasses exhibited objectionable wilting under daily irrigation at 100% ETo. Increasing K in relation to N failed to increase drought resistance for the cultivars studied. The bermudagrasses had the least drought resistance and PF and SD the most."
