The overall goal of this research was to characterize components of legume seeds, and determine if specific seed components have potential functional properties for practical end-uses. The polymeric flavonoids proanthocyanidins (PA), also known as condensed tannins, accumulate in the seed coats...
Two field studies assessed sward dynamics to legume removal with and without Canada thistle and other broadleaf plants (i.e. forbs). When grown in mixtures with grass, alfalfa had a more consistent negative yield response to legume removal compared to clover swards. Within established pastures,...
Monitoring was continued at instrumented sites which were selected in spring 1976, at Mildred Lake, Supertest Hill, the GCOS dike, and near Richardson Tower. Because of budget limitations, sites at Richardson were only monitored occasionally. However, information was obtained at a number of...
Legume-grass forage mixes for maximizing yield and competitiveness against weeds in early establishmentDownload
A field experiment from 2003 to 2005 at two sites examined the impacts of forage species and legume proportion on forage sward production. Grasses generally established rapidly and out-yielded swards high in legume content, although legumes did improve forage quality. Alfalfa was retained at...
Long-term forage dynamics in pastures sprayed with residual broadleaf herbicide: A test of legume recoveryDownload
Legumes such as alfalfa (Medicago sativa L.) and white clover (Trifolium repensL.) are important components of northern temperate pastures where they increase forage productivity and quality, but are susceptible to decline when exposed to broadleaf herbicides. Little is known about the long-term...
Wild Rose Consulting, Inc. (Edmonton) and the Vegetation Branch of AEC (Vegreville) began a four year project in spring of 1990 to collect, multiply, evaluate, and select native legume species for inclusion in a native seed mixture being developed at AEC for reclamation in the mountains and...
Recovery of Legumes in Northern Temperate Pastures Following the Application of Broadleaf HerbicidesDownload
Field and greenhouse trials were conducted to assess the breakdown of soil residues of two broadleaf herbicide bioactives, aminopyralid and aminocyclopyrachlor, as well as associated legume reestablishment/recovery and pasture sward production dynamics. Greenhouse trials indicated legume seedling...
The results are reported of research into the revegetation of two areas on a steeply sloping dike composed of tailings sand from tar sand extraction at the Great Canadian Oil Sand Limited plant at Fort McMurray, Alberta. One area was seeded with three pasture grasses and two legumes in 1971 after...
The tailings sand slope that was seeded in July, 1976, was considered completely stable in 1977. No wind or water erosion or movement of soil particulates was detected in 1977. Of the fourteen species seeded in 1976, only Lupine and the oat cover crop did not grow in 1977. A comparison of fall...
Laboratory studies were conducted during 1976 to investigate native grasses and legumes potentially useful for revegetation on various soils. Plant growth was tested in various soils with and without the addition of fertilizer in the greenhouse and ill growth chambers. The Genera tested were:...
