Zoysiagrass is a commonly used turf species in lawns and golf courses in Arkansas, but little information is available regarding the management of these cultivars on golf courses or lawns in Arkansas. The objective of this study was to characterize a general response (color, density, turf quality, and disease incidence) to nitrogen fertilization, mowing, and their interactions among zoysiagrass cultivars. Turf density was improved when fertilizing ≥ 98 kg N/ha/year. Spring green-up was highest for 1.3 cm mown plots. Among 3.8 cm mown plots, higher nitrogen rates (≥ 195 kg N/ha/year) decreased spring green-up. Scalping was greatest when mowing at 1.3 cm and fertilizing with 293 kg N/ha/year. There was no advantage to fertilizing more than ≥ 98 kg N/ha /year. Turf quality was never unacceptable for the unfertilized check plots.
