Item Effects of fertilizers on a seeded highway slope turf at Whitehall, Montana(Montana State University - Bozeman, College of Agriculture, 1972) Salih, Mohamed Sid AhmedItem Determining the suitability of native grasses for highway revegetation sod(Montana State University - Bozeman, College of Agriculture, 2007) Stott, Lance Vear; Chairperson, Graduate Committee: Tracy A.O. Dougher.In past years, the California Department of Transportation (Caltrans) has used hydroseeding, imprinting and drill seeding methods to revegetate highway construction sites with varying degrees of success. Ecological concerns have led researchers to consider using native species for revegetation as they are better suited to local environments, require less maintenance and do not pose a threat to adjacent ecosystems. In addition, the urgency for stabilizing areas of high erosion potential and that of establishing native plant cover quickly in order to prevent non-native plant and weed establishment, have led researchers to consider using native grass sod for highway revegetation. Twenty-one species of native grasses were selected in order to determine their suitability for sod production. Grasses were grown in six growth chambers; each mimicking one of the climates of the six selected California ecoregions. Mixtures of varying species included either one rhizomatous species with three bunch grasses, one rhizomatous species and five bunch grasses, two rhizomatous species with three bunch grasses, or two rhizomatous species with five bunch grasses.Item Intermountain West native and adapted grass species and their management for turfgrass applications(Montana State University - Bozeman, College of Agriculture, 2006) Day, Toby Richard; Chairperson, Graduate Committee: Tracy A. O. Dougher.This research addresses irrigation and water use of native and adapted grasses for turfgrass application. For this purpose, plots were established at the MSU Horticulture Research Farm, Bozeman, MT. The selected native and adapted grass species include 12 single species and 12 mixed species stands of 'Cody' buffalograss, 'Foothills' Canada bluegrass, 'Bad River' blue grama, sheep fescue, Sandberg bluegrass, muttongrass, and wheatgrasses 'Sodar' streambank, 'Road Crest' crested, 'Rosana' western, and 'Critana' thickspike with Kentucky bluegrass and tall fescue as introduced species. A line source irrigation system was installed to allow the plots to be evaluated at four irrigation levels. Experimental measurements on the plots included growth response as determined by clipping yield and quality ratings for color, texture, and density. Estimated timing and recommended minimum amount of water for irrigation for the grasses and mixtures for Bozeman, Montana, was determined from the data. Single species and mixtures that had a good turf quality overall were sheep fescue, blue grama, buffalograss, and the mixture of buffalograss + sheep fescue.
