Resumo: | The objective of this work was to evaluate the influence of ryegrass (Lolium multiflorum) managements on the physical properties of a Haplohumox, and on the yields of corn and of ryegrass cultivated in succession to corn. The experiment was carried out in a randomized complete block design, with three treatments and three replicates, in which treatments were the different managements of ryegrass under no-tillage for silage, soil cover, and grazing. After nine years of management, samples were collected at 0.00–0.05, 0.05–0.10, 0.10–0.20, and 0.20–0.30-m soil depths, to determine the following soil properties: texture, total organic carbon, soil bulk density, macroporosity, microporosity, total porosity, and resistance to root penetration. The index of structural stability was estimated from texture and total organic carbon data. Maximum soil bulk density and permanent wilting point were also estimated from pedotransfer functions. Corn and ryegrass dry matter yields were determined from plants harvested inside the plot area. Total organic carbon content increased as depth increased. The ryegrass managements in no-tillage system, in succession to corn, does not influence the soil physical properties of a Haplohumox, and maintains high corn and ryegrass yields. |

O experimento foi realizado em blocos ao acaso, com três tratamentos e três repetições, em que os tratamentos foram os diferentes manejos do azevém, em sistema plantio direto, para silagem, cobertura do solo e pastejo. Após nove anos de manejo, coletaram-se amostras a 0,00–0,05, 0,05–0,10, 0,10–0,20 e 0,20–0,30 m de profundidade do solo, para a determinação dos seguintes atributos: textura, carbono orgânico total, densidade, macroporosidade, microporosidade, porosidade total e resistência à penetração de raízes. O índice de estabilidade estrutural foi estimado a partir dos dados de textura e carbono orgânico total. A densidade máxima do solo e o ponto de murcha permanente também foram estimados a partir de funções de pedotransferência. As produtividades de massa de matéria seca do milho e do azevém foram determinadas a partir da colheita na parcela. O conteúdo de carbono orgânico total aumentou com o aumento da profundidade. Os manejos do azevém em plantio direto, em sucessão ao milho, não influenciam os atributos físicos do Latossolo Bruno e mantêm altas as produtividades de milho e de azevém.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCoordenação de Aperfeiçoamento de Pessoal de Nível Superior (Capes)Vizioli, BrunoCavalieri-Polizeli, Karina Maria VieiraBarth, Gabriel2018-10-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/26011Pesquisa Agropecuaria Brasileira; v.53, n.8, ago. 2018; 952-960Pesquisa Agropecuária Brasileira; v.53, n.8, ago. 2018; 952-9601678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/26011/14274https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/26011/17697Direitos autorais 2018 Pesquisa Agropecuária Brasileirainfo:eu-repo/semantics/openAccess2018-10-19T20:43:08Zoai:ojs.seer.sct.embrapa.br:article/26011Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2018-10-19T20:43:08Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
