“…The unfertilized BG was similar in mean cumulative FM compared with the fertilized BGN treatment. The addition of N, especially in amounts ≤100 lb acre −1 yr −1 , may not always contribute to greater amounts of FM in seeded cultivars (Rushing et al., 2021). Greater cumulative forage harvested for BGA can be attributed to the contribution of alfalfa, during the spring months leading up to the onset of grazing (Figure 2).…”

Beef cattle (Bos taurus) production systems in the southeastern United States are often riddled with inefficiencies, particularly when it comes to forage management, and the lack of high‐quality forages utilized during the warmer months of the year. A grazing trial was conducted in east‐central Mississippi on a fine sandy loam soil in which bermudagrass (Cynodon dactylon L.) was interseeded with ‘Bulldog 505’ alfalfa (Medicago sativa L.). The randomized complete block design consisted of three treatments: (a) unfertilized bermudagrass (BG), (b) fertilized bermudagrass (100 lb N acre–1 yr–1) (BGN), and (c) bermudagrass interseeded with alfalfa (BGA). Forage production, along with animal performance, and economic analysis were compared across all three treatments for three grazing seasons (2017–2019). The BGA system had greater cumulative forage mass (FM), crude protein (CP), and total digestible nutrients (TDN) compared with the BG treatment. The BGA treatment had the greatest average daily gain (ADG; 1.83 lb head–1 d–1) and GAIN (178 lb acre–1). Based on increased forage and animal performance, the BGA treatment had a net revenue of US$75.61 acre–1, compared with the BG ($15.49 acre–1) and BGN (–$26.50 acre–1) treatments. Our results indicate that interseeding alfalfa into bermudagrass pastures has the potential to increase farm profitability, especially with fluctuations in N prices.

“…In the case of BB and SG, these findings were also expected based on trends in plant maturity [61]. Additionally, Rushing et al [62] evaluated the costs of feeding with weaned beef steers as being impacted by the hay yield and quality of several warm-season perennial grasses, including EG. They found that more frequent harvests (30-day intervals) provided greater digestible fibers, similar to in early harvests in the current study.…”

The identification of appropriate nitrogen (N) rates for native warm-season grasses (NWSG) is needed to inform forage management in the southeastern United States. Experiments were conducted in Knoxville and Springfield, TN, from 2015 to 2019, to evaluate dry matter (DM) yield, forage nutritive value (FNV), the influence of temperature and precipitation on yield, and partial factor productivity (PFP) responses. Three NWSG species (big bluestem [BB; Andropogon gerardii Vitman], switchgrass [SG; Panicum virgatum L.], and eastern gamagrass [EG; Tripsacum dactyloides L.]) were grown at each location and harvested twice annually. Five N rates in the form of urea were applied annually in split applications. The yields for all species responded positively to nitrogen (p < 0.001) and the time of harvest (p < 0.001) at both sites, except for BB yield at Springfield; no consistent N effects were observed over years. Nitrogen affected the FNV (p < 0.001) of all species, increasing CP by three to five percentage points (p < 0.001). Yields across all species and locations responded positively to precipitation (p < 0.001) and temperature (p < 0.001). A moderate N amendment (<135 kg N ha−1 yr−1, based on PFP) can enhance the productivity of NWSG, but responses were site-dependent and influenced by temperature and precipitation.

“…TDN, which is often a function of plant maturity (Rushing et al., 2021), was affected by grazing ( p < 0.0001) and tillage ( p = 0.0238), resulting in a grazing × tillage interaction ( p = 0.015). No differences were observed between species ( p = 0.0665).…”

Cover crop grazing can be used as a strategy to meet nutritional requirements for livestock while simultaneously enhancing soil ecosystem services without sacrificing subsequent crop yield. Field research was conducted in east‐central Mississippi from 2019 to 2021 on a sandy loam soil to assess the impacts that grazing, tillage, and cover crop species had on corn (Zea mays L.) grain yield and soil characteristics. The main plot was grazed (G) and un‐grazed (UG) cover crops, tillage (conventional and no‐till [NT]) was the subplot, and cover crop species the sub‐subplots. Cover crops were grazed using beef (Bos taurus) heifers at a stocking density of approximately 3300 kg ha−1 each growing season as forage mass (FM) allowed. No differences were observed in FM among cover crop treatments; however, FM, crude protein (CP), and total digestible nutrients (TDN) were affected by tillage and grazing. Corn grain yield was unaffected by grazing or tillage but was impacted by cover crop treatment. Cereal rye (Secale cereale L.; 11.99 Mg ha−1), crimson clover (Trifolium incarnatum L.; 11.67 Mg ha−1), and cereal rye + radish (Raphanus sativus L.; 12.07 Mg ha−1) had greater grain yield compared to the un‐planted control (10.99 Mg ha−1). The combination of G × no‐till (NT) resulted in greater penetration resistance (71.07 J); however, G plots contributed to greater organic matter(OM) concentrations. Overall, our data suggest that complimenting G and NT practices does not impact subsequent corn grain yield and could add value to cover cropping systems.
