Performance of American native grass cultivars in the Canadian prairie provinces

Abstract:

The cultivation of native grass cultivars developed for Montana and North Dakota has been proposed in the prairie region of western Canada. Cultivars of 6 warm-season and 4 cool-season grass species that had been selected for North Dakota or Montana were evaluated at a range of sites in western Canada for stand establishment, persistence, aboveground biomass, seed yield, and competitive ability. Warm-season grass cultivars were not adapted to sites above 51 √łtitude. At locations below this latitude, cool-season grasses produced more biomass than warm-season grasses. The occurrence of these warm-season grasses in native rangeland of this region is frequent but often restricted by landscape position or soil texture. Thus, they will likely have a minor role in revegetation seedings. Mammoth wildrye exhibited the highest biomass production on the highest productivity sites. All native cool-season grass cultivars evaluated were adapted to the prairie region of western Canada.
