Abstract
Five warm-season turfgrass [Zoysia japonica Steud., Stenotaphrum secundatum (Walt.) Kuntze, Buchloe dactyloides (Nutt.) Engelm., Eremochloa ophiuroides (Munro.) Hack. and Cynodon dactylon (L.) Pers.] were overseeded with 2 cool-season turfgrasses [Poa pratensis L. and Festuca arundinacea Schreb.] to examine suitability of these species for planting in mixture for producing a year-round turf. Percent of warm-season and cool-season turfgrasses in the mixture were estimated for 5 years. Also, to evaluate the fertilization times of the warm-season and cool-season turrfgras mixtures. Eremochloa ophiuroides and Buchloe dactyloides were not suitable for warm-season and cool-season turfgrass mixtures. However, Zoysia japonica, Stenotaphrum secundatum and Cynodon dactylon were suitable for warm-season and cool-season turfgrass mixtures. Zoysia japonica, Stenotaphrum secundatum and Cynodon dactylon were showed approximately 50% botanical composition five years after cool-season turfgrass overseeding. And, those three warm-season turfgrass mixtures showed approximately 20% visual ratings in winter period. Fertilization in early spring and late autumn had made cool-season turfgrass dominated in mixtures. Therefore, fertilization times in warm-season and cool-season turfgrass mixtures was desirable in summer period.
