Medicago Sativa L

AC Longview alfalfa (Medicago sativa L.) was developed by the Agriculture and Agri-Food Canada Research Centre, Lethbridge, Alberta. This cultivar, tested as LRS 93-1 in Uniform Alfalfa Tests in western Canada, is highly resistant to verticillium wilt (VW) and bacterial wilt (BW) and out-yielded Beaver (check) by about 9 and 12% in dryland and irrigated locations, respectively.

Moderately Resistant

AC Nordica alfalfa (Medicago sativa L.) was developed by the Agriculture Canada Research Station at Saskatoon, Saskatchewan. It is similar to Beaver alfalfa in having a broad crown and a tap root with many branches. AC Nordica is 1–2 d earlier in maturity than Beaver. It is shorter than Beaver at 10% bloom, is slightly slower in regrowth following harvest, and displays less spring vigor. However, it excels in winter hardiness, rating similar to Anik and Drylander alfalfa. AC Nordica is highly resistant to bacterial wilt (Clavibacter michiganense subsp. insidiosum [McCulloch] Davis, Gillaspie, Vidaver & Harris), and moderately resistant to snow mold (Coprinus psychromorbidus Redhead & Traquair). AC Nordica is intended as a special-purpose cultivar for the northern prairies, the Peace River area of Alberta, and other high snowfall areas where snow mold (winter crown rot) may occur and where extreme winter hardiness is required.

Dalton alfalfa (Medicago sativa) was developed by the Agriculture and Agri-Food Canada Research Centre, Lethbridge, Alberta. This cultivar, tested as LRC01CR in western Canada, is derived from parental clones that are both bacterial wilt (BW) and verticillium wilt (VW) resistant. When grown under irrigated and rainfed conditions for forage it out yielded Beaver (check) by 3%, for seed it out yielded Beaver on irrigation by 19%. Dalton is well suited to forage and seed production in western Canada where VW may be of concern. Key words: Cultivar description, alfalfa, Medicago sativa

Force Characteristics

Shearing force of alfalfa (Medicago sativa L.) stems was measured to evaluate genotype-by-year interactions. Based on mean shearing force for each stem segment and genotype clustering criteria, several genotypes had similarly shearing forces among years. Therefore, selecting genotypes with desirable shearing force characteristics to improve digestibility or intake potential of forages may be possible.

Medicago Sativa L

A study was conducted to monitor nutrient and microbial count changes during wilting of alfalfa (Medicago sativa L.) in response to varying degrees of maceration at mowing. Early bloom alfalfa was mowed with either a roller-conditioner (CONV) or a macerator set to deliver four degrees of maceration during alfalfa mowing: LIGHT, LIGHT+, SEVERE, and SEVERE+. Macerated alfalfa reached 80% dry matter in 9–11 h compared with alfalfa mowed by roller-conditioner, which required 54 h. The most rapid wilting rates were associated with LIGHT+, SEVERE, and SEVERE+ maceration treatments when alfalfa was not exposed to precipitation. The wilting coefficient in the first 24 h was increased by more than 100% for the SEVERE treatment compared with alfalfa mowed using a conventional roller-conditioner in alfalfa that was not exposed to precipitation. Precipitation at 1.5 h post-mowing increased wilting time by 8.3 h to achieve 45% DM, and by 17.5 to achieve 80% DM in the SEVERE+ maceration treatment relative to alfalfa from the same conditioning treatment that was not exposed to precipitation. Precipitation at 24 h post-mowing increased wilting time to reach 80% DM by 11 h and 21 h for the LIGHT and LIGHT+ maceration treatments relative to alfalfa of the same mowing treatments not exposed to precipitation. Maceration of alfalfa resulted in a 24.2 to 26.8 h shorter wilting time relative to the conventional roller-conditioner treatment when alfalfa was exposed to precipitation at 24 h post-mowing. SEVERE and SEVERE+ maceration treatments at mowing resulted in higher (P < 0.05) neutral detergent fibre and acid detergent fibre levels post-wilting. Lactic acid bacteria populations on alfalfa tended to be higher with maceration within 1 h post-mowing (P < 0.10) and post-wilting (P < 0.08). Key words: Alfalfa, maceration, precipitation, wilting time, bacteria, nutrient profile, compressibility
