Resumo: | A field experiment was conducted at the Agronomic Experimental Station of the Federal University of Rio Grande do Sul in Guaíba, RS, Brazil, during the 1981/82 growing season with the monocultures of dry beans (Phaseolus vulgaris L.), sunflower (Helianthus annuus L.) and corn (Zea mays L.) and also the intercropping of these species two by two. The main objective of this research was to compare intercrops and monocultures as to their competitive abilities aginst weeds. In general, the intercrops caused more reduction in weed growth than the correspondent sole crops, when these systems were compared by the phytomass index. Greater soil coverage was obtained by the foliage of the associated systems than by the sole crops. The bean monoculture also provided high soil coverage, although this system showed low efficiency in competing with weeds. On the other hand, sunflower demonstrated efficient competition ability against weeds. |

O objetivo da pesquisa foi o de comparar consórcios e monocultivos quanto à habilidade em competir com plantas daninhas. De um modo geral, os consórcios reduziram o crescimento das ervas, já que os índices de fitomassa das plantas daninhas foram menores nestes sistemas, em relação aos cultivos exclusivos. Foi obtida maior capacidade de cobertura vegetal sobre o solo nos sistemas associados. O monocultivo de feijão também propiciou elevada cobertura do solo, contudo tal sistema mostrou ser pouco eficiente em competir com as ervas. Já o girassol demonstrou ser uma espécie de eficiente habilidade na competição com as espécies daninhas.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFleck, Nilson GilbertoMachado, Carlos Marcírio NaumannSouza, Rodrigo Saldanha de2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15717Pesquisa Agropecuaria Brasileira; v.19, n.5, maio 1984; 591-598Pesquisa Agropecuária Brasileira; v.19, n.5, maio 1984; 591-5981678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/15717/9734info:eu-repo/semantics/openAccess2014-04-16T19:22:18Zoai:ojs.seer.sct.embrapa.br:article/15717Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T19:22:18Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
