We report detailed X-ray observations of the unique binary system $\epsilon$ Lupi, the only known short-period binary consisting of two magnetic early-type stars. The components have comparably strong, but anti-aligned magnetic fields. The orbital an

Building on results from the Magnetism in Massive Stars (MiMeS) project, this paper shows how a two-parameter classification of massive-star magnetospheres in terms of the magnetic wind confinement (which sets the Alfv��n radius RA) and stellar r

Publikováno v: Canadian Journal of Plant Science. 84:1037-1050

Agronomic and nutritive characteristics of 11 grasses were studied at Swift Current, Saskatchewan on a moderately saline irrigated soil: [smooth bromegrass (Bromus inermis Leyss.), meadow bromegrass (Bromus riparius Rehmann), tall wheatgrass (Elytrig

Four rates of nitrogen fertilizer (0, 50, 100 and 200 kg N ha-1) were applied for 4 yr to two replications of a 32-yr-old crested wheatgrass (Agropyron cristatum) pasture at Lanigan, Saskatchewan, after which no fertilizer was applied for a further 4

Assessing eight grass species for pasture by measuring etiolated spring regrowth

Autor: Herbert Lardner, S. B. M. Wright, R. D. H. Cohen

Publikováno v: Canadian Journal of Plant Science. 83:551-554

Grazing by herbivores can affect root carbohydrate reserves of grass species. A grazing study was conducted on an irrigated pasture near Outlook, Saskatchewan, Canada, during the summers of 1991 and 1992 t o determine etiolated regrowth after grazing

Publikováno v: Canadian Journal of Animal Science. 83:171-182

This paper presents predictions of pasture composition and liveweight gain of steers using the GrassGro simulation model. Predictions are compared with field data measured during a 4-yr experiment at Brandon, Manitoba, in which steers grazed alfalfa

Steer performance grazing hybrid bromegrass pastures

Autor: R. D. H. Cohen, L. C. Thompson, Herbert Lardner, B. E. Coulman

Publikováno v: Canadian Journal of Animal Science. 83:165-169

Producers in Saskatchewan require grazing information on new grass cultivars to improve production and quality of existing forage stands. Animal data are ultimately needed to validate the performance of these new varieties under grazed conditions. A

Publikováno v: Canadian Journal of Animal Science. 82:621-626

Rejuvenation of forage stands is probably the most economic and practical method to improve production and quality of forage stands. Animal data are ultimately needed to validate the viability of the rejuvenation technique. This study determined anim
