Eastern gamagrass [Tripsacum dactyloides (L.) L.] can serve as an alternative warm‐season perennial forage in the southeastern United States. A 2‐yr study was conducted to evaluate effects of (i) overseeding with cool‐season forages and (ii) N fertilization in the spring on herbage accumulation, nutritive value, and persistence of ‘Highlander’ eastern gamagrass. Overseeding treatments included: control (no overseeding), early‐maturing ‘Florida 401’ rye (Secale cereale L.), mid‐maturity ‘Wrens Abruzzi’ rye, and a mixture of ‘Wrens Abruzzi’ and ‘AU Red Ace’ red clover (Trifolium pratense L.). During late spring, eastern gamagrass was fertilized with either 67 or 135 kg N ha−1 to evaluate growth response following overseeding and differing N input levels. Herbage accumulation (kg dry matter [DM] ha−1) and nutritive value (in vitro dry DM digestibility and crude protein) were measured during the cool‐ and warm‐season production window. Forage canopy cover and botanical composition determinations measured persistence and compositional change during each growing season. Mob‐stocking was implemented every 28 d to simulate rotational grazing. There was no effect of overseeding with cool‐season annual grasses or grass–legume mixtures on seasonal eastern gamagrass herbage accumulation or persistence during the trial. Cool‐season forage herbage accumulation in this study was limited. Spring N fertilization stimulated a rapid growth response in eastern gamagrass, but N‐level effects dissipated as the season progressed. Results indicate that overseeding may be a viable option in eastern gamagrass swards, but given the low level of cool‐season forage production observed in this study, evaluation of additional cool‐season species/blends and economic viability of this system is needed.

Rhizoma peanut (Arachis glabrata Benth.) is an important hay crop in the southern United States. Since rhizoma peanut is a warm‐season perennial legume, it remains dormant during the cool season. Overseeding rhizoma peanut during the cool season could optimize land productivity per unit area throughout the year. However, the effect of overseeding on rhizoma peanut performance in the following growing season is unknown. This study evaluated different combinations of rye (Secale cereale L. ‘FL401’) and/or ryegrass (Lolium multiflorum Lam. ‘Prine’) mixed or not with clovers (Trifolium spp.) overseeded on dormant ‘Florigraze’ rhizoma peanut. Rye–clover mixtures resulted in greater herbage accumulation (6,040 lb ac−1 yr−1) than grass monocultures, clovers, and rye–ryegrass mixtures. However, rye–clover mixtures had similar herbage accumulation to rye–ryegrass–clovers (5,640 lb ac−1 yr−1) and ryegrass–clovers (4,560 lb ac−1 yr−1). Crude protein (CP) concentration in grass was greater for rye and rye–ryegrass (9.8%, for both) than in ryegrass monoculture (8.2%), nonetheless, it was similar to other treatments (9.1%, on average). Ryegrass and ryegrass–clovers resulted in the greater in vitro digestible organic matter (IVDOM) for the grasses (81%, on average) than all other treatments (70%, on average). Overseeding rhizoma peanut did not affect its herbage responses. On average, herbage accumulation, CP, and IVDOM for Florigraze rhizoma peanut in the first harvest following the overseeding treatments were 3,845 lb ac−1, 14.2%, and 75.7%, respectively. Results indicate that overseeding cool‐season grass–legume mixtures would optimize forage production per unit area and improve forage nutritive value without compromising rhizoma peanut herbage responses in the growing season.

Overseeding cool‐season annual grasses into dormant lowland switchgrass stands

Improved use of the land resource used to grow switchgrass (SG; Panicum virgatum L.), whether for biomass or forage production, could be achieved by dormant-season overseeding with cool-season annual grasses (CAGs). Cereal rye (Secale cereale L.), ryegrass (Lolium multiflorum Lam.), and wheat (Triticum aestivum L.) were overseeded into an established, mature stand of lowland ('Alamo') SG for two consecutive years (2010-2011) at a study site located near Greeneville, TN. Three harvest timings were imposed on CAG (15 April, 1 May, and 15 May). Yield of CAG differed (p = 0.001) by year, species (rye = 6.8, ryegrass = 5.0, wheat = 5.1 Mg ha −1), and harvest time (15 April = 2.7, 1 May = 6.5, 15 May = 7.7 Mg ha −1), but these factors did not interact. Switchgrass yield the summer following establishment of CAGs differed (p = .001) by year (11.1 and 14.7 Mg ha −1 , in 2011 and 2012, respectively) but not by CAG species or harvest date. Tiller density of SG followed the same pattern as yield (2011 = 75 m −2 ; 2012 = 147 m −2). Thus, this study provided no evidence that any of the three CAGs, when planted for two consecutive years into dormant SG, regardless of harvest date, had a negative effect on SG yield or stand vigor; therefore, overseeding CAGs may be a practical way for producers to improve land resource use when growing SG. However, evaluation of production costs for CAGs indicated that May harvests would be required for overseeding to be cost-effective.
