After agronomic evaluation of a large collection, 21 ecotypes were pre selected for multilocational trial was thus to evaluate the persistence and carying capacity of these eight new Brachiaria brizantha ecotypes after two years of grazing. The experimental design was a randomized complete block with nine treatment and two replicates. The experimental area was divided into 18 paddocks of 1000m. The were grazed acording to a deferred flexible system. After two years. it was possible to selected four ecotypes, which were indicated for animal performance trials aiming at releasing at least one of them as a new cultivar in 2002.(ID n. 13-13).p. 535-536.openAccessBrachiaria BrizanthaPastagemPastejoTaxa de LotaçãoCarrying capacityPasturesStocking rateArtigo em anais e proceedings
