“…A small grain companion crop is sometimes used to facilitate alfalfa establishment (7). Forage quality is usually highest in weed-free stands (7,11,15). Once alfalfa is established, other herbicides may be used, such as paraquat applied to dormant alfalfa and between cuttings (6,9), imazethapyr or a postemergent grass herbicide (2,13), or residual herbicides such as pronamide and metribuzin, depending on the production system used (8,12).…”

Weed control is one of the factors that impact alfalfa producers, with negative effects on quality often in the year of establishment. Glyphosate is a broad‐spectrum herbicide that controls many troublesome annual and perennial weeds, and new cultivars that are tolerant of glyphosate application have been developed. The crop response of glyphosate on these new varieties has not been reported. This research examined alfalfa tolerance under field conditions, and high rates were used to challenge the plants to determine the level of safety. Postemergent glyphosate treatments ranging from 0.75 to 3 lb a.e./acre sprayed before each of four alfalfa harvests had no meaningful crop injury in the establishment year or in the subsequent two years. The high glyphosate dose of 9 lb a.e./acre over a 3‐year period caused no reduction in alfalfa yield or nutritive value at any cutting in any of the three years.

“…In areas such as the Canadian prairies, there is little time for forage growth after the companion crop is harvested. In these areas, forage yields are normally reduced for at least 1 yr after establishment with a companion crop (Kilcher and Heinrichs 1960;Waddington and Bittman 1983;Moyer 1985;Zaman et al 2003). In some studies, the yield loss effect of companion crops was observed on forage legume stands for up to 4 yr after establishment (Moyer 1989;Moyer et al 1995).…”

. 2006. A review of research progress on cicer milkvetch (Astragalus cicer L.). Can. J. Plant Sci. 86: 49-62. This review of cicer milkvetch includes both published and unpublished information regarding crop and seed characteristics, seed treatments, breeding, agronomic practices and nutritional value for livestock. Cicer milkvetch is a long-lived perennial, acid-and drought-tolerant crop providing high-quality forage throughout the growing season. It does not cause bloat in ruminants. Although it has caused photosensitization in ruminants, this was apparently due to specific environmental conditions and the cultivar used. Cicer milkvetch is compatible with other forage crops in mixed stands and is particularly suitable for pasture. Although the crop has many good qualities and was introduced in North America approximately 75 yr ago, it has not been utilized extensively, primarily due to slow establishment. However, stand establishment has been improved by elucidation of seed and seedling characteristics, followed by selection for heavy seed, rate of emergence, and mature plant vigor. Improved cultivars, developed through recurrent selection for rapid establishment, are now available. Seed scarification, inoculation with rhizobia, and shallow seeding into a pre-packed, warm seedbed are of great importance in cicer milkvetch establishment. Seeding later in the spring (without a companion crop) increases the probability of successful establishment of genetically improved cultivars. Development of cultivars with upright growth characteristics and long-term persistence under grazing stress, improved scarification techniques (to reduce seed loss), and a seeding protocol for successful establishment of the crop, have the potential to substantially increase utilization of this important forage legume. Cette revue bibliographique englobe l'information connue et inédite sur les caractéristiques de la plante et de la graine, les traitements grainiers, l'hybridation, les pratiques agronomiques et la valeur nutritive de cette culture pour le bétail. L'astragale est une vivace longévive qui tolère bien les sols acides et la sécheresse; elle produit un fourrage de haute qualité pendant toute la période végétative. Elle n'entraîne pas le météorisme chez les ruminants. La photosensibilisation qu'elle engendre à l'occasion chez eux semble résulter de certaines conditions environnementales ainsi que du cultivar employé. L'astragale est compatible avec d'autres plantes fourragères dans les peuplements mixtes et se prête particulièrement bien aux pâturages. En dépit de ses nombreuses qualités et de son introduction en Amérique du Nord il y a près de 75 ans, l'astragale n'est pas énormément utilisée, principalement parce qu'elle prend du temps à s'implanter. On peut néan-moins améliorer l'établissement de la culture en triant les semences et les plantules d'après leurs propriétés puis en sélectionnant les plants pour une production abondante de graines, le taux de levée et la vigueur des plants adultes.

“…One of the most common reasons of stand impairment is weeds. Zaman et al (2003) reported that lucerne stands produce very weedy forage in first year when herbicides are not used. On the other hand, Brown et al (2005) determined that lucerne has good persistence, being 94% (dryland) and 55% (irrigated) of botanical composition of swards in the sixthyear.…”

“…Decline in lucerne stand density has little direct effect on lucerne hay quality, but ingress of weeds into lucerne stands as a resuit of stand aging results in lower hay quality (Sheaffer et al 1988). As forage plants mature, ADF increases and digestibility of the forage decreases (Zaman et al 2003). In general, ADF and NDF contents are higher for grasses than pure légumes (Cherney et al 1997).…”

The effects of a range of stand ages on lucerne were studied over three locations in Erzurum, Turkey. Dry matter yield, weed ratio, plant density and content of crude protein (CP), acid detergent fibre (ADF) and neutral detergent fibre (NDF) were determined in stands of different ages. Stand age reduced the dry matter yield and increased weed ratio and density. This yield reduction was from 5533 kg ha -1 (in the second year) to 3039 kg ha -1 (in the seventh year). Lucerne plant density was the highest (225.6 plants m -2 ) in the establishment year. It reduced in the subsequent years, while weed densities increased with stand age. Protein, ADF and NDF content in forage were strongly affected by increased stand age. In general, the crude protein content decreased, while ADF andNDF contents increased, with aging. The results of this study showed that lucerne persisted well for 6 years and produced high yields with low weed content under irrigated conditions in Erzurum.
