Resumo: The objective of this work was to evaluate the performance of cover crops regarding biomass production and nutrient accumulation and release during the off-season in a clayey Red Latossol (Ferralsol) in the Cerrado. The assay was carried out at Santo Antônio de Goiás and Rio Verde, GO, Brazil from November/2007 to October/2008. A randomized block design in a split-plot arrangement in time was used, with the cover crops evaluated in the main plot and with biomass sampling time in the subplot, with four replicates. The evaluated species were: Urochloa brizantha, U. ruziziensis, Pennisetum glaucum e U. ruziziensis + Cajanus cajan and, as reference, a fallow treatment with spontaneous vegetation. Sampling times were six in Santo Antônio de Goiás and five in Rio Verde, since the desiccation date of P. glaucum, 60 days after cover crop sowing. P. glaucum showed the largest quantities of dry biomass at the beginning of the off-season, while the other covers showed significant accumulations of biomass and nutrients at the end of the off-season.

O delineamento experimental foi o de blocos ao acaso, em esquema de parcelas subdivididas no tempo, com as plantas de cobertura avaliadas nas parcelas principais e com os períodos de coleta de fitomassa nas subparcelas, com quatro repetições. As espécies avaliadas foram: Urochloa brizantha, U. ruziziensis, Pennisetum glaucum e U. ruziziensis + Cajanus cajan e, como referência, pousio com vegetação espontânea. As épocas de coleta foram seis em Santo Antônio de Goiás e cinco em Rio Verde, a partir da data de dessecação do P. glaucum, aos 60 dias após a semeadura. O P. glaucum apresentou as maiores quantidades de fitomassa seca no início da entressafra, enquanto as outras coberturas apresentaram acúmulos significativos de fitomassa e nutrientes no final da entressafra.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFundação Agrisus, Projeto PRODESILP-FINEP, CAPES.Pacheco, Leandro PereiraLeandro, Wilson MozenaMachado, Pedro Luiz Oliveira de Almeidade Assis, Renato LaraCobucci, TarcísioMadari, Beáta EmokePetter, Fabiano André2011-03-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/9443Pesquisa Agropecuaria Brasileira; v.46, n.1, jan. 2011; 17-25Pesquisa Agropecuária Brasileira; v.46, n.1, jan. 2011; 17-251678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/9443/6178https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/9443/4656info:eu-repo/semantics/openAccess2014-05-14T17:43:20Zoai:ojs.seer.sct.embrapa.br:article/9443Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-05-14T17:43:20Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
