Evaluation of forage species under savanna poor soil drainage conditions

[摘要] - Six Paspalum and four legumes accessions were evaluated to identify forage species adapted to poor soil drainage conditions. The experiment was carried out during three successive years, in Modelo Farm, Terenos county (MS, Brazil), in "cerrado" type field area, just after the removing of the natural vegetation, on a poor Plinthaquox soil drainage conditions. Dry matter and green matter yields were evaluated by cuttings done at three, six, nine and 12 weeks after a plot cut uniformity in times that represent the dry and rainy seasons of each experimental year. The legumes accessions did not survive the experimental conditions. Among the grasses, the Paspalum guenoarum (BRA 010707) accession was very well adapted and it is recommended for further studies aiming the release of a new forage plant option for commercial enterprise.
