This study examined the improved effect of wear tolerance of warm-season turfgrass overseeded with cool-season turfgrasses. Also, it investigated the improved effect of crumb rubber on wear tolerance and the difference anmong cultivars regarding the wear of Zoysia spp. In wear experiment during summer, the warm-season turfgrass overseed with cool-season turfgrasses had a higher visual rating on the ground than the monostand of Cynodon dactylon. Moreover, in wear experiment in winter, barrenness showed significant progress in the monostand of C. dactylon, while the barrenness did not appear at all in overseeded turf with cool-season turfgrasses. As a result of investigating the bulk density was increased in the monostand of C. dactylon, but not in the overseed turf with cool-season turfgrasses. From the above result, the wear tolerance effcect of turfgrasses appeared year round through warm-season and cool-season turfgrass mixtures. Also, it was found that the method of topdressing crumb rubber on the ground was effective as a physical assistant device alleviating damage of turfgrasses. The possibility of improving wear tolerance was accepted by adding soil amendments such as perlite, pamis, etc., in order to promote the growth of turfgrass.
