Abstract/Contents:"On May 7, 1996, 6 zoysiagrass (Zoysia spp) cultivars were planted in College Station, Texas. Genotypes used included Meyer, El Toro, Crowne, and Palisades, which are medium to coarse textured, as well as Emerald and Cavalier, which are fine textured. After most plots were established, nitrogen fertility was differentially applied in the form of 21-0-0 at the rates of 0.25, 0.5, or 1.0 lbs N per 1000 sq ft per month during the growing season. Mowing height differentials were imposed in August 1996, and included cutting heights of 0.75 inches via a reel-type mower, and 1.5 inches with a walk behind rotary mower. Plots were rated visually for spring greenup on 24 March, 1998, and there were no significant differences between cultivars or fertility rates, but plots mowed at 0.75 in. were greener than those mowed at 1.5 in. When the plots mowed at 0.75 inch were rated monthly for quality, there were usually no statistical differences in turf quality between cultivars, except that Meyer was often rated in the lowest statistical group, and the other cultivars were in the highest statistical group. The same relationship held true for the overall seasonal average for turf quality. At the 1.5 inch mowing height, there were quality differences between cultivars on almost every rating date. Meyer was in the lowest statistical group on each date and overall. Both Cavalier and Emerald, as well as Meyer, exhibited better quality at the lower mowing height than at the 1.5 in. height. Mowing height had no effect on quality among the other cultivars. At the 0.75 in. mowing height, the highest (1.0 lbs N per 1000 sq. ft. per month) fertility level produced the highest quality turf. At the 1.5 in. mowing height, the highest fertility level produced the highest quality turf except for Emerald, which produced turf of similar quality regardless of fertility level. All other cultivars exhibited better fall color than Meyer, and Emerald was greener than El Toro."
