Some Ecological Observations on Turf Establishment and Culture of Turfgrasses in Cool Regions of Japan
- Y. Oohara
Turf areas such as golf courses, roadsides, sports grounds, home lawns, and public parks are becoming more important each year in Japan. Interest in turf has stimulated a series of ecological and physiological investigations of turf establishment on golf courses, roadsides, and banks along rivers by the Turf Science Laboratory of Obihiro University of Agriculture and Veterinary Medicine, located in the northern part of Japan.
Among the 10 cultivars tested, ‘Penncross’ and ‘Seaside’ creeping bentgrass (Agrostis palustris Huds.) were best adapted for golf course greens. ‘Fylking,’ ‘Baron,’ and ‘Nugget’ Kentucky bluegrass (Poa pratensis L.), ‘Pennlawn’ red fescue (Festuca rubra var. rubra L.), and ‘Jamestown’ chewings fescue (Festuca rubra var. commutata Gaud.) were selected from the tests for fairways. Legumes such as New Zealand white clover (Trifolium repens L.), ‘Emerald’ crown vetch (Coronilla varia L.); and some birdsfoot trefoil (Lotus corniculatus L.) cultivars were adaptable as turf for damsites roadsides, and river banks.
As for cultural practices, attention should be directed to the preparation of the seedbed, mulching, fertilization, reseeding to get uniform stand density, proper mowing, and the application of herbicides or fungicides where necessary. From these experimental results, the author was able to obtain some favorable information on turf cultivars adaptable to the cool regions of Japan and to identify cultural practices for the establishment and maintenance of cool-season turfgrasses.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
