“…When the first derivative of regression equations was taken, ground cover was greatest at N rates from 3.6 to 4.3 g N m −2 wk −1 Optimal N rates observed here are similar to that used (4.4 g N m −2 wk −1 ) to establish TifEagle and Floradwarf ultradwarf hybrid bermudagrasses on high‐sand putting greens (Rodriguez et al, 2002). Bunnell et al (2005a) demonstrated that both N rate and mowing height affected lateral regrowth of TifEagle (measured June–Aug. ), with regrowth increasing 5% when mowing height was raised from 3.2 to 4.7 mm, and increasing when additional N was applied.…”

“…In established ultradwarf hybrid bermudagrass turf, recent research has examined light requirements of TifEagle (Bunnell et al, 2005a(Bunnell et al, , 2005b, and N source and cultivation effects on four ultradwarf cultivars (Hollingsworth et al, 2005). Another study evaluated N and K, and length of photoperiod on growth and TNC content of 'FloraDwarf' in a glasshouse experiment (Trenholm et al, 1998).…”

In the southeastern United States, ‘TifEagle’ hybrid bermudagrass [Cynodon dactylon (L). Pers. × C. transvaalensis Burtt Davy] has become a selected cultivar for renovated or new bermudagrass putting greens, and its use has increased in popularity. However, there is limited research which examines TifEagle establishment, especially when cultural practices such as mowing height are included in the experimental design. The objective of this research was to evaluate the impact of N rate and mowing height on the percentage ground cover, shoot density, color, total nonstructural carbohydrate (TNC) content, and soil nitrate (NO3–N) and ammonium (NH4–N) content of TifEagle hybrid bermudagrass putting greens throughout three establishment years (2002, 2003, and 2004). Weekly applications of N were applied at 0.3, 0.6, 1.2, 2.4, and 4.8 g N m−2 wk−1, and mowing height applied at 3.2, 3.9, and 4.8 mm. Almost every agronomic measure (percentage ground cover, shoot density, root or rhizome and stolon mass, color) responded to increased applications of N, with maximum ground cover and shoot density reached at N rates from 3.4 to 4.3 g N m−2 wk−1 Turf mowed under the lowest mowing height often had reduced turfgrass color and rhizome and stolon mass, compared with that mowed at 3.9 or 4.8 mm. Soil pH and residual NO3−N and NH4–N were almost always affected by N rate, but not by mowing height. For rapid establishment without significant reductions in shoot density, rhizome and stolon mass, and TNC, the highest N rate of 4.8 g N m−2 wk−1, as used in this study, was not needed.

“…In nature, trees alter spectral quality available for turfgrass development (Bell et al, 2000); however, limited research has investigated the light specific tree species filter in highly maintained turfgrass environments. Also, most turfgrass shade research has focused on light quantity using black neutral shade material (Bell and Danneberger, 1999; Koh et al, 2003; Steinke and Stier, 2003; Bunnell et al, 2005a; Baldwin et al, 2008).…”

Warm‐season turfgrass quality declines under shade due to reduced photosynthesis, increased disease pressure, reduced carbohydrate production, tree root competition, and reduced lateral stem growth. Another factor limiting turfgrass growth and development under tree shade is variable qualities of light filtered by trees. However, effects of various filtered wavelengths on turfgrass performance are lacking and deserve research. Therefore, a greenhouse project investigated the physiological and morphological responses of ‘Diamond’ zoysiagrass [Zoysia matrella (L.) Merr.], ‘Sea Isle 2000’ seashore paspalum (Paspalum vaginatum Swartz.), and ‘Tifway’ and ‘Celebration’ bermudagrass [Cynodon dactylon (L.) Pers. × C. transvaalensis Burtt‐Davy] to variable light spectral qualities. Light treatments included a control without any shade cloths and four different color shade cloths filtering wavelengths 560 to 720 nm (blue shade cloth), 360 to 520 nm (yellow shade cloth), 360 to 560 nm (red shade cloth), and 360 to 720 nm (black shade cloth). The percent light reduction for each cloth was about 65% relative to the control. Data collected included visual turfgrass quality (TQ), relative clipping yield, relative chlorophyll concentration, relative shoot width, relative root biomass, relative root length density, relative specific root length, and root and shoot total nonstructural carbohydrates. Diamond was the least affected turfgrass by the color shade cloths, while Celebration and Sea Isle 2000 performed similarly. Tifway was the most sensitive turfgrass with the lowest TQ under color shade cloths. Yellow and red shades were least detrimental, while black shade most negatively inhibited parameters measured, followed by blue shade. This study implies different types of shade significantly impact the TQ of warm‐season turfgrasses.

“…Establishment and maintaining aesthetics and functional values of bermudagrass greens and tees includes identifying ideal application rates and seasonal applications of fertilizers, topdressing, and frequency of horizontal and vertical mowing and aerification (Bunnell et. al., 2005; Hollingsworth et al, 2005; Guertal and Evans, 2006; Rodriguez et al, 2001; White et al, 2004). After evaluation of vertical mowing and topdressing, management strategies for establishing and established ‘Tifdwarf’, Champion, FloraDwarf, ‘Miniverde’, and TifEagle ultradwarf bermudagrass cultivars in temperate Texas (White et al, 2004) suggested that cultural management will need to change as the cultivars mature.…”

To provide optimum playing surfaces, many golf courses have used ultradwarf bermudagrass [Cynodon transvaalensis Burtt Davy × C. dactylon (L.) Pers.] cultivars for greens, although little is known about regionally defined cultural management. A 4‐yr experiment was conducted in southern Florida, on a US Golf Association (USGA)‐specified green to examine the effect of topdressing and vertical mowing frequency on ultradwarf bermudgrass cultivars Champion, TifEagle, and FloraDwarf for primarily quality, growth, tissue N and K, and ball roll distance. Weekly topdressing during the wet season enhanced quality and reduced the presence of disease‐like symptoms. TifEagle increased aboveground growth when topdressed weekly compared with Champion and FloraDwarf. As the green aged, however, topdressing biweekly during dry‐season months became important for maintaining quality. Influence of vertical mowing on all observations and measurements were minimal and not consistent from season to season. Further long‐term research is needed to determine how changing mechanical management on a seasonal basis can optimize ultradwarf bermudgrass for quality, vigor, and performance.
