“…'Serala', an early sericea lespedeza release, produced maximum herbage accumulation when harvested at 9-wk intervals in Alabama, nearly 9000 kg DM ha -1 yr -1 , but declined 41% when harvested at 6-wk intervals (Hoveland and Anthony, 1974). ), accumulate up to 9000 kg DM herbage ha -1 yr -1 in similar climates with prolonged cool seasons (Carvalho and Quesenberry, 2012), while Stylosanthes spp. These herbage accumulation values are difficult to compare with those of other perennial warmseason legumes due to differences in growing conditions.…”

Condensed tannins (CT) from sericea lespedeza [Lespedeza cuneata (Dumont de Courset) G. Don], a hardy and widely adapted forage legume, have potential for methane emission suppression, rumen protein bypass, gastrointestinal nematode suppression, and pest fly suppression in ruminants. Nitrogen (N) from this herbaceous legume can also be an important component of crude protein in ruminant diets. The concentrations and yields of CT and N, however, have not been studied across a wide range of environments, harvest regimens, or plant maturities. Our results from Texas and Georgia indicate that CT concentrations increased with rainfall, decreased with maturity, and were highly dependent on harvest regimen (P ≤ 0.05). Condensed tannin concentrations ranged (P ≤ 0.05) from 32.7 to 106.1 g CT kg−1 dry matter (DM) and CT DM yields from 274 to 771 kg ha−1 yr−1. Nitrogen concentrations ranged (P ≤ 0.05) from 14.6 to 28.4 g kg−1 DM and N DM yields from 46 to 231 kg ha−1 yr−1. If pellets or hay of sericea lespedeza are to be commercialized specifically for their CT and N content, analysis and labeling will be beneficial because of this variability.

“…() evaluated the effect of several seedling arrangements on the establishment of BRA‐14951 pintoi peanut and observed that the seedling density of 4 plants/m 2 (similar to observed in this experiment) covered around 40% of soil surface at 112 days after planting. However, Carvalho and Quesenberry () reported that several accessions of pintoi peanut had slow establishment in North Florida, with none of the tested genotypes covering more than 50% of the soil around 1 year after planting. Reasons for the differences in ground cover between the current study and previous literature are likely related to the differences in weed pressure, as the authors mentioned above removed weeds manually while such practice was not done in the present study.…”

“…Pintoi peanut is another warm‐season perennial legume that has been studied in South America during recent decades, with documented persistence under grazing on acidic and low‐fertility soils (Rao & Kerridge, ). In comparison with rhizoma peanut, it has the advantage of producing viable seeds, with some genotypes producing more than 1 Mg/ha of seed (Carvalho & Quesenberry, ). Establishing seed‐propagated plants is usually more convenient and less expensive than establishing vegetatively propagated plants; therefore, pintoi peanut might be an alternative to rhizoma peanut in subtropical regions.…”

“…Similar to rhizoma peanut, the establishment of pintoi peanut is generally slower than the establishment of warm‐season grasses, although it varies according to location and cultivar (de Assis, Valentim, Carneiro, de Azevedo, & Ferreira, ; Carvalho & Quesenberry, ; Perin, Guerra, & Teixeira, ).

Pintoi peanut (Arachis pintoi Krapov. & W.C. Greg.) is a warm‐season perennial legume with potential for use in grass–legume mixtures in Florida; however, limited information exists about its establishment in mixtures with bahiagrass (Paspalum notatum Flügge). The objective of this experiment was to evaluate the establishment of bahiagrass cv. “Argentine” and pintoi peanut cv. “Amarillo” as monocultures or mixture. The experiment was conducted in Ona, FL, from June to October of 2014 and 2015. Treatments were a split‐plot design of seeding strategies (bahiagrass monoculture, pintoi peanut monoculture or bahiagrass‐pintoi peanut mixtures; main plots) and two N fertilization strategies (30 or 80 kg/ha N; 30N and 80N; subplots), with four replicates. Measurements of plant density and frequency were taken every 4 weeks after seeding. Ground cover and herbage mass (HM) measurements were taken 112 days after seeding. Pintoi peanut ground cover was affected by seeding strategy × N level interaction. Ground cover was greater with 80N than 30N when pintoi was seeded in monoculture (3.6% vs 1.5% respectively) but not when it was seeded with bahiagrass (2.1%). There was no effect of seeding or N strategy on pintoi peanut proportion in HM (1.4%). Bahiagrass ground cover was not affected by seeding or N strategy (15.9%); however, its proportion in the HM was greater in 80N than 30N (12.1% vs 9.4% respectively). Mixed seeding did not negatively affect the establishment of bahiagrass and pintoi peanut and greater N fertilization levels improved some establishment parameters, with no negative effect for pintoi peanut.

Global and midwestern U.S. agriculture requires diversification and new sources of protein for sustainable crop production. Mung bean [Vigna radiata (L.) R. Wilczek] as a legume crop has a long cultivation history in Asia; however, its potential lays hitherto underexplored in the United States. As a first step towards exploring mung bean for crop diversification in northern latitudes, crop germplasm centers that harbor worldwide crop resources need to be used. This study explores the potential of mung bean in the U.S. northern latitudes through the utilization of the USDA germplasm resources. Complete collection of USDA mung bean germplasm was screened under Iowa field conditions in 2017, to shortlist 482 accessions to create an Iowa mung bean panel. The Iowa mung bean panel was further characterized for field adaptability traits in 2018 and 2019 and genotyped using genotype‐by‐sequencing (GBS) to conduct association mapping of important traits. Genetic markers were identified for both quantitative trait (days to flowering [DTF], plant height [PHT], leaf drop at maturity [LDMS], 100‐seed weight [SDWT], and Fusarium wilt score [WS]) and qualitative traits (seed color [SC], seed‐coat texture [ST], hypocotyl color [HC], and pod color [PC]). We report FERONIA, a known flowering‐pathway gene, as the candidate gene for the quantitative trait locus (QTL) with largest effect on DTF. In addition, important epistatic interactions were also uncovered for WS and SDWT. Further, accessions with desirable magnitude of traits were identified as potential parents. Diversity analyses and field phenotypic data indicate potential for mung bean improvement to suit midwestern U.S. cultivation.
