Persistence of Selected Tropical Pasture Legumes in Peninsular Florida1

  1. W. D. Pitman and
  2. A. E. Kretschmer2



The potential N contribution of tropical legumes to grass pastures on the infertile soils of Peninsular Florida necessitates increased efforts to develop suitable pasture legumes. Nineteen accessions representing 17 tropical legume species were evaluated for persistence under grazing in bahiagrass swards on a Peninsular Florida Arenic Haplaquod (Spodosol) soil. After three growing seasons in the mixed grass-legume swards, only Vigna parkeri Bak. and aeschynomene (Aeschynomene americana L.) covered larger areas than were originally planted. Indications of potential adaptation to flatwoods pastures were also obtained with ‘Florida’ carpon desmodium [Desmodium heterocarpon (L.) DC], phasey bean [Macroptilium lathyroides (L.) Urb.], Vigna adenantha (G.F. Meyer) Marechal, Mascherpa, and Stainier and Vigna luteola (Jacq.) Benth. However, the variation in response of these four accessions among field replications indicates that site and management requirements of these legumes need further investigation.
