“…The interaction occurred because the undisturbed palisadegrass sward treatment had greater HM and LAI in January and February, but there was no difference among treatments in March and April. Relatively smaller CP concentrations associated with control treatments was due to greater palisadegrass growth, which resulted in a dilution effect (Vendramini et al, 2013). Limited palisadegrass HM in March and April was due to unfavorable climate conditions.…”

“…Palisadegrass plots overseeded with pintoi peanut had lesser canopy height and leaf/stem ratio and greater CP concentrations than palisadegrass undisturbed swards (Table 4). Relatively smaller CP concentrations associated with control treatments was due to greater palisadegrass growth, which resulted in a dilution effect (Vendramini et al, 2013).…”

“…Averaged across all treatments, pintoi peanut ground cover increased from February to May (from 14 to 23%, P = 0.02, SE = 3). Vendramini et al (2013) observed that bahiagrass (Paspalum notatum Flugge) pastures overseeded with stylo [Stylosanthes guianensis (Aublet.)

“…Results from previous studies indicated that differences in grass and legume morphology affected the HM and tiller density of both species in grass-legume mixed swards. Vendramini et al (2013) observed that bahiagrass (Paspalum notatum Flugge) pastures overseeded with stylo [Stylosanthes guianensis (Aublet.) Sw] had similar total (bahiagrass + stylo) HM as non-overseeded pastures (bahiagrass only); however, the stylo was 17% of the total HM, indicating that bahiagrass HM decreased when legume was present in the mix.…”

Pintoi peanut (Arachis pintoi Krapovickas & Gregory) is a warm‐season perennial legume that has been used in grass–legume mixtures; however, management practices to successfully establish pintoi into warm‐season grass swards have not been fully examined. Two experiments were conducted to evaluate different sward compositions and methods of establishment of pintoi peanut or pintoi peanut–palisadegrass [Urochloa brizantha (A. Rich.) R.D. Webster] mixed swards. The first experiment evaluated pintoi peanut and palisadegrass established as monocultures or in a pintoi peanut–palisadegrass mixture. Pintoi peanut ground cover and density was greater for pintoi peanut than pintoi peanut–palisadegrass mixed swards (29 vs. 8%, and 42 vs. 19 plants m−2 for ground cover and density, respectively). Concomitant seeding of pintoi peanut and palisadegrass showed no negative effect on palisadegrass herbage mass (HM). In the overseeding experiment, treatments were: (i) peanut interseeded into glyphosate‐treated rows subsequently strip tilled into prepared seedbed strips (0.4 m) with intervening untilled areas (2 m); (ii) peanut no‐till seeded into glyphosate‐treated rows (0.4 m) with intervening untilled areas (2 m); and (iii) an undisturbed sward of palisadegrass with no pintoi peanut. Prepared seedbed and no‐till treatments had similar pintoi ground cover (2.9%), density (8.7 plants m−2), spread (11.7 cm), and HM (170 kg ha−1 yr−1). Glyphosate treatment of rows followed by no‐till seeding was an effective strategy to establish pintoi peanut into palisadegrass swards. Pintoi peanut contribution during the early stages after establishment is insufficient to generate sufficient biological N fixation and produce forage for livestock.

Productivity of tropical and subtropical grasslands is often limited by inadequate nitrogen (N) supply. Aeschynomene (Aeschynomene americana L.) is a warm‐season legume that may contribute as N input in grazing systems, but there is limited information about aeschynomene litter decomposition and N dynamics on pastures. The objective of this study was to quantify the effect of overseeding aeschynomene or applying N fertilizer to existing bahiagrass (Paspalum notatum Flüggé) on litter disappearance and decomposition rates. The study was conducted in Ona, FL, from October 2019 to May 2020 and October 2020 to May 2021. Treatments were the split‐plot arrangement of bahiagrass‐aeschynomene or bahiagrass monoculture (main plot) and N fertilization level, (0 [control] or 60 kg N ha−1) as subplot, distributed in a randomized complete block design with four replicates. The nylon bag technique was used to estimate organic matter (OM), N and carbon (C) disappearance, and lignin concentration for 184 days of incubation. Bahiagrass‐aeschynomene had greater OM disappearance (from 330 to 356 g kg−1 OM) and was driven by C disappearance. Nitrogen fertilization did not impact litter decomposition responses, except for C:N ratio. Overseeding aeschynomene is an effective management practice to increase OM decomposition and optimize nutrient cycling in warm‐season pastures.

Overseeding aeschynomene and N fertilization effects on forage characteristics, N fixation, and N₂O‐N emissions of bahiagrass pastures

Aeschynomene (Aeschynomene americana L.) is a warm‐season annual legume forage used in tropical and subtropical regions; however, there is limited information on agronomic and environmental benefits of aeschynomene when overseeded into bahiagrass (Paspalum notatum Flüggé) swards. The objective of this study was to evaluate the effects of overseeding aeschynomene or applying N fertilizer to existing bahiagrass on forage characteristics, atmospheric N fixation, and N2O‐N emissions. The study was conducted in Ona, FL, from April 2019 to March 2021. Treatments were the split‐plot arrangement of bahiagrass‐aeschynomene or bahiagrass monoculture (main plot) and N fertilization level (0 or 60 kg N ha−1; subplot), distributed in a randomized complete block design with four replicates. Nitrogen fixation was estimated in plots receiving no N fertilization. The static chamber technique was used to estimate N2O‐N emissions. Overseeding aeschynomene did not increase forage accumulation (mean = 1300 kg dry matter [DM] ha−1 harvest−1) or N2O emissions (mean = 15 g N2O‐N ha−1 per day), but increased forage crude protein (CP) concentration (from 98 to 108 g kg−1) when compared to bahiagrass monoculture. Nitrogen fertilization increased forage accumulation (from 1200 to 1400 kg DM ha−1 per harvest) but it did not affect aeschynomene N fixation (84% N derived from atmospheric fixation [Ndfa]). Nitrous oxide emissions had significant temporal variability across all treatments; however, there were no differences in accumulated N2O‐N emissions among treatments (mean = 2.4 kg N2O‐N ha−1 per year). Overseeding aeschynomene is an effective management practice to increase forage CP concentration in pastures without increasing N2O‐N emissions.
