“…Mowing zoysiagrasses is more challenging than with bermudagrass. Zoysia leaves and stems are tougher, more fibrous, and difficult to cut (Beard, 1973; Duble, 1996) and are reportedly higher in silica (Ruemmele and Engelke, 1990; Joo et al, 1999). Sharp blades (preferably on a cylinder rather than a rotary mower) are essential to give a clean cut through the leaves with minimal damage, and more regular sharpening is necessary because of tough leaf blades (D. Koster, personal communication, 2015).…”

The genus Zoysia Willd. comprises ±10 recognized species indigenous to the western Pacific Rim and Indian Ocean, which are collectively called “zoysiagrasses.” Three species—Z. japonica Steud., Z. matrella (L.) Merr., and Z. pacifica (Goudswaard) M. Hotta & Kuroki (previously referred to as Z. tenuifolia)—plus interspecific hybrids have a long history of use as warm‐season perennial turf and ornamental grasses in many countries. Recently, cultivars from two other species, Z. macrantha Desv. and Z. sinica Hance, have also been developed. Breeders are currently exploring the potential to incorporate attributes from these and other Zoysia species into future zoysiagrass cultivars through hybridization. The attributes of Zoysia turfgrass cultivars—their strengths and limitations—can be related back to the species and germplasm from which they have been derived, and which (together with growth and development characteristics unique to the zoysiagrasses) ultimately determine their adaptation, use, and management. Differences in temperature, shade, drought, salinity, and traffic tolerance, as well as differences in nutritional and mowing requirements among zoysiagrasses, plus comparisons with Cynodon spp. turfgrasses, are highlighted.

Nitrogen Rate and Mowing Height Affect Seasonal Performance of Zoysiagrass Cultivars

et al. 2018

Core Ideas Nitrogen rate had a greater impact on turfgrass quality of zoysiagrass when the grass was actively growing, but the effect of mowing height was only significant during spring green‐up. Nitrogen rate of 171 kg ha−1 was suitable for consistent turf performance in zoysiagrass and the effect of increasing N rate from 171 to 268 kg per ha was minimal. Japanese lawngrass and manilagrass can be successfully maintained at 2.5 or 5.0 cm and 0.6 or 1.2 cm, respectively, for equivalent performance during the majority of the year; however, during spring green‐up, the lower mowing height may deliver better turf performance. As new zoysiagrass (Zoysia spp.) cultivars are released, field studies on N responses and mowing heights conducted over several years under different environments are needed to determine best management practices. This study was initiated to (i) characterize a general response (color, density, turf quality) to N fertilization rate, mowing height, and their interactions among zoysiagrass cultivars; and (ii) establish appropriate mowing height and N rate recommendations for each of the cultivars studied. Four Japanese lawngrass cultivars (Z. japonica Steud.) and four manilagrass cultivars (Z. matrella L. Merr.) were evaluated in Citra, FL, for 4 yr and in Raleigh, NC, for 2 yr under three N rates (73, 171, and 268 kg ha−1 yr−1) and two mowing heights (2.5 and 5.0 cm for Japanese lawngrass; 0.6 and 1.2 cm for manilagrass). Genetic differences were evident among the zoysiagrass cultivars. Nitrogen rate had a greater impact on most of the observed characteristics when the grass was actively growing, but the effect of mowing height was only significant during spring green‐up. The medium N rate was suitable for consistent turf performance throughout the year and the effect of increasing N rate from 171 kg ha−1 to 268 kg ha−1 was minimal. Japanese lawngrass and manilagrass can be successfully maintained at 2.5 or 5.0 cm and 0.6 or 1.2 cm, respectively, for equivalent performance during the majority of the year. However, during spring green‐up, the lower mowing height may deliver better turf performance.
