“…The grass mix containing timothy and meadow fescue, known to be sensitive to frequent defoliations, performed nearly as well in terms of seasonal forage DM yield over three post-seeding years as the grass mix with tall fescue and meadow bromegrass, known for their greater tolerance to frequent defoliations. In a previous study conducted in eastern Canada, timothy, meadow fescue, tall fescue, and meadow bromegrass grown in binary mixtures with a legume species and grazed or frequently cut persisted well over five postseeding years (Bélanger et al 2018). Our results confirm that four recommended forage grass species in eastern Canada, including timothy and meadow fescue, perform well under the type of grazing management used in our study and the study of Bélanger et al (2018), whether they are in binary or complex legume-grass mixtures.…”

“…The contribution of the legume species to forage DM yield across sites and grass mixes ranged from 18% to 49% in the first post-seeding year, 1% to 17% in the second post-seeding year, and 2% to 29% in the third postseeding year (Table 5). The poor contribution of both legume species to forage DM yield in the second and third post-seeding years could be attributed to poor grazing tolerance, poor winter survival (Bélanger et al 2006), a strong competition from the forage grasses, and (or) selective gazing in the first post-seeding year observations (Bélanger et al 2018). In a recent study conducted in Nova Scotia with the grazing of binary legume-grass mixtures, the low proportion of alfalfa and birdsfoot trefoil after the second post-seeding year was attributed to selective grazing by cattle based on visual observations (Bélanger et al 2018).…”

“…As compared with alfalfa, birdsfoot trefoil (Lotus corniculatus L.) is a slow-growing species with a lower yield potential but with a greater tolerance to poor growing conditions (e.g., soil acidity and poor drainage). Both birdsfoot trefoil and a grazing-type alfalfa 'AAC Trueman' (previously referred to as CRS1001) performed well in binary mixtures with a grass species under grazing or frequent cutting (Bélanger et al 2018).…”

Complex pasture mixtures are advantageous, but little information exists on the best forage species and nitrogen (N) management in eastern Canada. We compared under mob stocking four complex mixtures of one of two legume species [alfalfa (Medicago sativa L.) and birdsfoot trefoil (Lotus corniculatus L.)] plus one of two grass mixes [No. 1 — timothy (Phleum pratense L.), meadow fescue (Schedonorus pratensis (Huds.) P. Beauv.), reed canarygrass (Phalaris arundinacea L.), and Kentucky bluegrass (Poa pratensis L.); No. 2 — tall fescue (Schedonorus arundinaceus (Schreb.) Dumort., nom. cons.), meadow bromegrass (Bromus biebersteinii Roem. and Schult.), reed canarygrass, and Kentucky bluegrass] under three N application rates at three sites over the first three post-seeding years. Legume species had little effect on most forage attributes mainly because of their low contribution to forage dry matter (DM) yield (<30%) in second and third years. The grass mix with tall fescue and meadow bromegrass (No. 2) yielded similar or slightly better than the one with timothy and meadow fescue (No. 1) but tended to have a greater neutral detergent fibre concentration, and lower N and total digestible nutrient concentrations. Nitrogen fertilization increased forage DM yield only in second and third years when the legume contribution to forage DM yield was <30%, and it increased N concentration and decreased nonstructural carbohydrate concentration. These results highlight the challenge of maintaining legume species in rotationally grazed pastures of eastern Canada and confirm recommendations of applying no or little N fertilizer on grazed legume–grass mixtures when the legume contribution to forage DM yield is >30%.

Cowpea (Vigna unguiculata L. Walp) (CW) is being considered as an alternative feed source in the southern U.S. Legume–grass mixtures are known to provide greater forage mass compared with unfertilized grass monocultures; however, research is needed to evaluate alternatives for increasing forage availability during the summer. The objective of this study was to quantify forage mass, nutritive value, and economic viability of CW overseeded in tall fescue [Schedonorus arundinaceus (Schreb.) Dumort.] (TF) and sorghum × sudangrass hybrid [Sorghum bicolor (L.) Moench × Sorghum sudanese (P.) Stapf] (SS) swards seeded at different rates. Two experiments were established in Spring Hill, TN, one with TF and the other with SS, from June to September of 2016 and 2017. Inoculated CW seeds were drilled into TF and SS plots at 25, 50, or 75 lb acre−1 and compared with control treatments that were without CW. There were no differences in total and average forage mass of TF or SS with the addition of CW, regardless of the seeding rate, likely due to the competitiveness of the grasses. No differences among seed rates were observed in the concentration of crude protein (CP) for TF swards mixed with CW in either year while in vitro dry matter digestibility (IVDMD) was less for the control treatment in 2017. Meanwhile, the nutritive value of the SS and CW mixture was improved as the CW seeding rate increased in both years. Data from this study suggest that the addition of CW to TF or SS does not justify its cost given the minimal benefit provided.

Seeding legumes into established cool‐season grass pasture helps to lower the long‐term costs of production and may improve total forage yield and quality, but seeding these legumes in the semiarid Central Great Plains region is often ignored. Eight legumes commonly seeded in the Midwest and eastern USA were no‐till seeded in late winter into upland and lowland west‐central Kansas smooth bromegrass (Bromus inermis Leyss.) pastures. Purple‐flowered alfalfa (Medicago sativa L. ssp. sativa) and yellow‐flowered alfalfa [Medicago sativa L. ssp. falcata (L.) Arcang.] established well at the lowland and upland sites and helped improve forage yield compared with nitrogen‐fertilized smooth bromegrass. Korean lespedeza [Kummerowia stipulacea (Maxim.) Makino] and yellow sweetclover [Melilotus officinalis (L.) Lam.] established well on both landscape sites, but these legumes declined significantly over time and did not increase forage yield compared with smooth bromegrass alone. Legume establishment was greater in unfertilized smooth bromegrass at each landscape, indicating that early competition from the grass limited legume establishment. Purple‐flowered and yellow‐flowered alfalfa increased the crude protein concentration compared with smooth bromegrass alone on the lowland site, and increased crude protein and total digestible nutrient concentration on the upland site. Birdsfoot trefoil (Lotus corniculatus L.), cicer milkvetch (Astragalus cicer L.), and hairy vetch (Vicia villosa Roth) failed to establish with competition from smooth bromegrass at the upland and lowland sites. Purple‐flowered and yellow‐flowered alfalfa may establish and persist when seeded into existing smooth bromegrass pastures in the drier regions of central Kansas while increasing forage yield and nutritive value.
