“…The increase in common bermudagrass infestation occurred because application of glyphosate in the pastures overseeded with stylo suppressed bahiagrass regrowth allowing common bermudagrass to increase. Similar results were also observed in bahiagrass pastures overseeded with annual ryegrass in the autumn (35).…”

Overseeding warm‐season legumes into warm‐season perennial grass pastures is an option to improve forage quality and reduce the use of commercial N fertilizer. The objective of this study was to evaluate the effects of ‘Ubon’ stylo (Stylosanthes guianensis var. vulgaris × var. pauciflora) overseeded into bahiagrass (Paspalum notatum Flügge) pastures on forage production and nutritive value. Treatments were overseeding stylo into bahiagrass pastures, bahiagrass pastures fertilized with 60 kg N/ha/year, or control (bahiagrass pasture with no N fertilization or legume) arranged in a randomized incomplete block design with three replicates. All treatments were continuously stocked using a fixed stocking rate with two heifers (Bos spp.) per experimental unit. Forage evaluations were conducted every 28 days from July to October 2010 and 2011. Pastures fertilized with N had greater herbage mass (HM) and herbage allowance (HA) than overseeded or control treatments and there was no difference between overseeded and control treatments. Overseeded and N fertilized treatments had greater CP concentration than control. The proportion of Ubon stylo was constant in the overseeded pastures during the experiment (≈ 17%). The increased HM on N fertilized treatments may potentially allow greater stocking rates when compared to pastures overseeded with stylo.

“…Vendramini et al. (2012) reported a similar trend where they observed that ARG CP and in vitro digestible organic matter were greatest in conventionally prepared seedbeds compared to other sod preparations techniques. They attributed this effect to an increase in reproductive tillers altering the leaf/stem ratio, thus negatively affecting nutritive value.…”

“…Vendramini et al. (2012) found that simple glyphosate application on bahiagrass before overseeding can result in ARG yields similar to those observed in conventionally planted annual ryegrass. If DM yields were not suppressed in the overseeded treatment, perhaps the cultivar effect may have been more dynamic.…”

Annual ryegrass (Lolium multiflorum; ARG) is often overseeded into bahiagrass (Paspulum notatum Fluegge) sod to provide early spring forage and extend the grazing season. Ryegrass cultivar selection for beef producers in the U.S. southeast is a major management decision, but most data available through state variety testing programs evaluate cultivar performance only from cultivated conventional seedbeds. Most producers do not consider the possible effect of ARG selection on total yield and nutritive value when overseeding into a sod compared to conventional management. Twenty ARG cultivars were planted into conventionally prepared seedbeds and overseeded into established bahiagrass plots. Forage dry matter, nutritive value, and bahiagrass suppression indexes were collected in 2019 and 2020 to determine the effects of ARG cultivar on these variables. Cultivar did not significantly affect dry matter, nutritive value, or bahiagrass suppression when overseeded. Seasonal yield of ARG decreased up to 55% in the overseeded plots and nutritive value generally decreased when compared to conventionally planted stands. Though ARG cultivars offered no apparent advantage or disadvantage to performance when overseeded, differences between planting methods were less apparent in later harvests. Considering the overseeding method involved little sod prep other than a no‐till drill, it was concluded that more intense sod preparation may have led to more dynamic results among ryegrass cultivars in the fall.

“…Sod‐seeded cool‐season annual forages provide a high‐quality feed source for wintering weaned calves (1,4,6). However, forage production by sod‐seeded cool‐season annuals may lag behind that of cool‐season annuals seeded using conventional tillage methods (12,16) because the competitive nature of bermudagrass (13) can delay grazing initiation (15) and reduce animal grazing days/acre (13,15). The majority of the studies reporting grazing of sod‐seeded cool‐season annuals in the southeastern USA have planted in late October to mid November (4,9,17).…”

A total of 120 Gelbvieh × Angus crossbred heifers (552± 2.5 lb initial BW) grazed pastures of common bermudagrass [Cynodon dactylon (L.) Pers.] overseeded with wheat (Triticumaestivum L.) and annual ryegrass (Lolium multiflorum Lam.) for a 3‐year study to compare the effect of seeding dates and tillage intensities on heifer growth performance. Half of the pastures were seeded in early September (Early) and half in mid October (Late). Within seeding date, half of the pastures were disked once (1×) and half were disked twice (2×) before seeding. Grazing began when forage mass reached approximately 2000 lb/acre and continued through 11 May 2002 (year 1), 25 April 2003 (year 2), and 10 May 2004 (year 3). Forage mass was greater from Early than from Late seeded pastures for 2 of the first 3 months of grazing resulting in 17‐day earlier grazing initiation and approximately 165 lb less hay fed per heifer. Total body weight gain, or gain while grazing cool‐season annuals did not differ between seeding dates or tillage intensities. Producers in the Mid South region with bermudagrass pastures may have considerable flexibility in their decisions as to when to seed annual forages and to what intensity they till their sod depending upon how soon they need available forage.
