Resumo: The objective of this work was to evaluate the effects of lignin, hemicellulose, and cellulose concentrations in the decomposition process of cover plant residues with potential use in no-tillage with corn, for crop-livestock integrated system, in the Cerrado region. The experiment was carried out at Embrapa Cerrados, in Planaltina, DF, Brazil in a split plot experimental design. The plots were represented by the plant species and the subplots by harvesting times, with three replicates. The cover plants Urochloa ruziziensis, Canavalia brasiliensis, Cajanus cajan, Pennisetum glaucum, Mucuna aterrima, Raphanus sativus, Sorghum bicolor were evaluated together with spontaneous plants in the fallow. Cover plants with lower lignin concentrations and, consequently, higher residue decomposition such as C. brasiliensis and U. ruziziensis promoted higher corn yield. High concentrations of lignin inhibit plant residue decomposition and this is favorable for the soil cover. Lower concentrations of lignin result in accelerated plant decomposition, more efficient nutrient cycling, and higher corn yield.

O experimento foi conduzido na Embrapa Cerrados, Planaltina, DF, em parcelas subdivididas. As plantas de cobertura representaram as parcelas, e a época de colheita representou as subparcelas, com três repetições. Avaliaram-se as espécies de plantas de cobertura Urochloa ruziziensis, Canavalia brasiliensis, Cajanus cajan, Pennisetum glaucum, Mucuna aterrima, Raphanus sativus, Sorghum bicolor, bem como as plantas espontâneas em pousio. Plantas de cobertura com menores concentrações de lignina e, consequentemente, com maiores taxas de decomposição de resíduos vegetais como C. brasiliensis e U. ruziziensis promoveram maior produtividade de milho. Concentrações elevadas de lignina inibem a decomposição dos resíduos vegetais e isso é favorável a cobertura do solo. As menores concentrações de lignina resultam em decomposição acelerada de resíduos vegetais, ciclagem mais efetiva de nutrientes e maior produtividade de milho.Em processamentoEmbrapa Informação TecnológicaPesquisa Agropecuária Brasileira2017-12-07T04:56:14Z2017-12-07T04:56:14Z2011info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfPesq. agropec. bras.,v.46,n.10,p.1200-1205,2011http://repositorio.unb.br/handle/10482/27990https://dx.doi.org/10.1590/S0100-204X2011001000012Carvalho, Arminda Moreira deSouza, Lara Line Pereira deGuimarães Júnior, RobertoAlves, Pedro Cesar Almeida CastroVivaldi, Lúcio Joséinfo:eu-repo/semantics/openAccessengreponame:Repositório Institucional da UnBinstname:Universidade de Brasília (UnB)instacron:UNB2024-08-27T21:16:02Zoai:repositorio.unb.br:10482/27990Repositório InstitucionalPUBhttps://repositorio.unb.br/oai/requestrepositorio@unb.bropendoar:2024-08-27T21:16:02Repositório Institucional da UnB - Universidade de Brasília (UnB)false
