“…Over the duration of the 3‐yr experiment, percentage of white clover in the sward decreased from 42 to 12 (Table 2). The decrease in white clover contribution as sward age increases has been well documented (Matches, 1989; Lomas et al, 2004; Bouton et al, 2005). Chapman et al (1996) reported white clover proportions in New Zealand swards average 10 to 20%, suggesting this research had typical proportions except in 2010 when clover percentage was high.…”

Little research has been conducted in the northern United States to evaluate meadow fescue [Schedonorus pratensis (Huds.) P. Beauv] or tall fescue [S. arundinaceus (Schreb.) Dumort] in pastures, and implications for animal performance. is research compared swards containing meadow fescue (MF) or tall fescue (TF) alone or co-established with white clover (Trifolium repens L.). Pastures were rotationally grazed with crossbred beef steers (Bos taurus, initial weight 261 kg, n = 180) using a variable stocking rate to detect treatment di erences. Sward white clover percentage decreased as the trial progressed (42, 25, and 12 for years 1, 2, and 3, respectively), coinciding with decreased steer performance. Swards containing TF had greater available forage (3200 vs. 2800 kg ha -1 ) and less in vitro true digestibility, neutral detergent ber digestibility, and steer average daily gain (ADG) (0.84 vs. 0.98 kg d -1 ) (P < 0.05) than MF swards. Adding white clover to MF and TF swards improved forage quality, steer ADG (0.98 vs. 0.84 kg d -1 ), and animal gain per hectare (780 vs. 680 kg ha -1 ) (P < 0.05) vs. monoculture grass pastures. Steers on MF pastures had greater ADG than TF pastures, but because TF pastures had greater stocking rate, gain per hectare was not di erent for the two grasses (728 vs. 735 kg) (P > 0.05). ese results demonstrate the superior forage quality and animal performance of MF pastures, the higher productivity of TF pastures, and the need for a productive, persistent legume in upper Midwest pastures.

“…Birdsfoot trefoil never established amid established grass competition in the current study, even with heavy autumn grazing prior to spring seeding, and was similar to the reduced establishment observed with competition by Min and Moyer (2015). White clover is easily established and widely distributed in eastern Kansas, which has abundant growing season precipitation, and white clover persistence over several years is able to substantially improve the nutritive value of cool‐season and warm‐season grass pastures (Lomas et al., 2004; Lomas & Moyer, 2020; Moyer & Lomas, 2017). However, in the current study, white clover lacked persistence, initially establishing on unfertilized locations only, then quickly disappearing in the subsequent growing season.…”

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.
