Abstract/Contents:"A part of an ongoing research project funded by the Pennsylvania Department of Transportation, an experiment evaluating seven single species treatments and five turf mixtures (Table 1) was established September, 1987, in the median of SR 220 near Tyrone, Blair County, PA. Prior to seeding the site was treated with 3 lb ae glyphosate/acre, the killed vegetation was mowed, and the seedbed was prepared with an Olathe model 83 turf overseeder. The treatments were drop seeded onto 12 by 30 ft plots arranged in a randomized complete block design with three replications. The site has not been fertilized. A selective broadleaf weed treatment of 2,4-D, MCPP, and dicamba at 1.22, 0..65, and 0.11 lb ae/acre, respectively, was applied July 17, 1988. The site was mowed at a height of 3.5 in on August 7, 1990. Visual ratings of percent green turf and weed cover were taken May 22, August 6, and October 7, 1991. Turf cover tended to be low for the May 22 and August 6 ratings, but this is more an indication of poor 'green-up' and drought stress, rather than poor cover, as there was generally less than 5 percent base soil in the plots. There was a severe drought throughout the growing season, with below average rainfall for every month from April through October. The only species that were truly poor were the 'Tioga' deertongue grass and the perennial ryegrass, which was very thin in the ryegrass alone plots, and nearly non-existent in combination plots. Canada bluegrass was rated poorly on August 6, but this type of summer dormancy has been consistently observed with this species. 'Kentucky 31' tall fescue was rated best for turf cover October 7, and had few weeds. The turf type tall fescue also provided good turf cover, but had significantly more weeds than 'Kentucky 31'. The different fine fescue treatments performed similarly, provided excellent ground cover, but were rated lower for green turf cover than 'Kentucky 31' tall fescue."
