Resumo: | The objective of this work was to evaluate the potential of winter‑cycle cover crops on the protection of soil, in the southwest region of the state of Paraná, in Southern Brazil, as affected by coverage rate, dry matter (DM) production, C/N ratio, and maintenance of remaining DM of vegetable residues on soil surface. The following were used as cover crops: black oat (Avena strigosa), annual ryegrass (Lolium multiflorum), rye (Secale cereale), white lupine (Lupinus albus), common vetch (Vicia sativa), wild radish (Raphanus sativus), and consortia between black oat + common vetch (O+V) and black oat + common vetch + wild radish (O+V+R). The experiment was evaluated during the 2010/2011 and 2011/2012 growing seasons. Plant decomposition was determined with the use of litter bags. Black oat and the consortia provided higher rates of soil coverage at the first 50 days after sowing, with DM production higher than 2,600 kg ha-1 on soil surface. The consortia between O+V+R had a balanced C/N ratio and intermediate decomposition in relation to single cropping, promoting 1,045 kg ha-1 residue on soil surface, 120 days after its management. Forage grasses alone and consortia with forage grasses show higher soil protection potential. |

Foram utilizados como cobertura do solo: aveia‑preta (Avena strigosa), azevém (Lolium multiflorum), centeio (Secale cereale), tremoço‑branco (Lupinus albus), ervilhaca comum (Vicia sativa), nabo forrageiro (Raphanus sativus) e consórcios entre aveia‑preta + ervilhaca comum (A+E) e aveia‑preta + ervilhaca comum + nabo forrageiro (A+E+N). O experimento foi avaliado durante os anos agrícolas 2010/2011 e 2011/2012. A decomposição das plantas de cobertura foi determinada com uso de bolsas de decomposição (“litter bags”). A aveia‑preta e os consórcios proporcionaram maiores taxas de cobertura do solo aos primeiros 50 dias após a semeadura, com aporte de MS superior a 2.600 kg ha-1 na superfície do solo. O consórcio entre A+E+N apresentou relação C/N equilibrada e decomposição intermediária em relação ao cultivo solteiro, tendo promovido 1.045 kg ha-1 de palhada sobre o solo, 120 dias após seu manejo. Gramíneas puras e consórcios com gramíneas apresentam maior potencial de proteção do solo.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCAPESCNPqUTFPRZiech, Ana Regina DahlemConceição, Paulo CesarLuchese, Augusto VaghettiBalin, Nilson MarcosCandiotto, GilvaneiGarmus, Taís Gabriele2015-05-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/20934Pesquisa Agropecuaria Brasileira; v.50, n.5, maio 2015; 374-382Pesquisa Agropecuária Brasileira; v.50, n.5, maio 2015; 374-3821678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/20934/12927https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/20934/13090info:eu-repo/semantics/openAccess2015-05-27T20:56:49Zoai:ojs.seer.sct.embrapa.br:article/20934Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2015-05-27T20:56:49Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
