Resumo: The objective of this work was to evaluate the performance of nonprotected (by fences or pickets) seedlings of leguminous tree species and an equitable mix of these species, introduced in pastures of Brachiaria  brizantha cv. Marandu and Panicum maximum cv. Tanzânia, in the presence of cattle. The experimental design was a completely randomized one, in a 2x5 factorial arrangement, with two grasses (marandu and tanzânia) and four leguminous species (Mimosa artemisiana, Pseudomanea guachapele, Enterolobium contortisiliquum,Acacia  farnesiana), and a mix of these species, with three replicates. Evaluations were made for: seedling height, stem diameter, canopy diameter, seedling survival, pasture frequency and ant occurrence. The statistical difference between the means of the main canonical variable, by the test of Scott-Knott, indicated the formation of three groups, standing out the one formed by M. artemisiana and mixture of leguminous in the two pastures, plus E. contortisiliquum and A. farnesiana in pastures of marandu and tanzânia grass, respectively. Differences between the means of treatments for each variable, calculated by means of Bonferroni’s intervals of confi dence,showed that M. artemisiana presented the greatest height and seedling survival in the pasture of marandu grass. This leguminous seedlings, without protection, are indicated to be introduced in pastures of marandu grass in the region, in the presence of cattle.

Marandu e Panicum maximum cv. Tanzânia, na presença de gado. O delineamento experimental foi o inteiramente ao acaso, em esquema fatorial 2x5, duas gramíneas (marandu e tanzânia) e quatro espécies de leguminosas (Mimosa artemisiana, Pseudosamanea guachapele, Enterolobium contortisiliquum, Acacia farnesiana e uma mistura dessas espécies), com três repetições. Avaliaram-se: altura da muda, diâmetro do caule, diâmetro da copa, sobrevivência da muda, freqüência de pastejo e ocorrência de formigas. As diferenças estatísticas entre as médias da variável canônica principal, pelo teste de Scott-Knott, indicaram a formação de três agrupamentos, tendo-se destacado o grupo formado pelos tratamentos M.  artemisiana e mistura de leguminosas, nos dois pastos, mais E.  contortisiliquum e A.  farnesiana, nos pastos dos capins marandu e tanzânia, respectivamente. Diferenças entre as médias dos tratamentos relativas a cada variável, calculadas por meio de intervalos de confi ança de Bonferroni, mostraram que mudas de M. artemisiana apresentaram maior altura e sobrevivência em pasto de capim-marandu. Mudas dessa leguminosa, sem proteção, são indicadas para ser introduzidas, nas pastagens de capim-marandu da região, na presença do gado.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraPesagro e EmbrapaDias, Paulo FranciscoSouto, Sebastião ManhãesAzevedo, Bruno Campbell deVieira, Márcia de SouzaColombari, Aline AlvesDias, JulianaFranco, Avílio Antônio2008-10-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/620Pesquisa Agropecuaria Brasileira; v.43, n.10, out. 2008; 1413-1419Pesquisa Agropecuária Brasileira; v.43, n.10, out. 2008; 1413-14191678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/620/5531info:eu-repo/semantics/openAccess2014-07-17T19:16:05Zoai:ojs.seer.sct.embrapa.br:article/620Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-07-17T19:16:05Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
