Resumo: | The objective of this work was to survey the weeds in the preharvest of the sunflower crop in growers field of the southwest regions of Goiás State (Chapadão do Céu, Jataí and Montividiu) and Chapadão do Sul, Mato Grosso do Sul State, Brazil. Fifty one farms were evaluated, during the period of May to June, 2002, in a total of 583 m2 of area. The weeds were identified and counted inside a square (1.0x1.0 m), applied in each area, in order to determine the frequency, density, abundance and relative importance. Volunteer soybean (Glycine max) and corn (Zea mays) are part of the weed species in sunflower crop in the area. The botanical families Poaceae, Asteraceae and Euphorbiaceae present larger number of species. The main weeds found in the area are, in decreasing order, Ageratum conyzoides, Chamaesyce hirta, Cenchrus echinatus, Bidens sp., Euphorbia heterophylla and Commelina benghalensis. |

Foram amostradas, no período de maio a junho de 2002, 51 propriedades dos quatro municípios, totalizando uma área de 583 m2. As espécies daninhas foram identificadas e contadas mediante a aplicação de um quadrado de 1,0x1,0 m, colocado ao acaso dentro da área ocupada pelas lavouras. Foram obtidos os valores de freqüência, densidade, abundância e índice de importância relativa. Plantas voluntárias de soja e de milho fazem parte da flora daninha infestante de lavouras de girassol dessa região. As famílias Poaceae, Asteraceae e Euphorbiaceae são as que apresentam maior número de espécies. As principais plantas daninhas infestantes na região são, em ordem decrescente, Ageratum conyzoides, Chamaesyce hirta, Cenchrus echinatus, Bidens sp., Euphorbia heterophylla e Commelina benghalensis.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraBrighenti, Alexandre MagnoCastro, Cesar deGazziero, Dionísio Luiz PisaAdegas, Fernando StornioloVoll, Elemar2003-05-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6620Pesquisa Agropecuaria Brasileira; v.38, n.5, maio 2003; 651-657Pesquisa Agropecuária Brasileira; v.38, n.5, maio 2003; 651-6571678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6620/3677info:eu-repo/semantics/openAccess2014-08-11T19:11:09Zoai:ojs.seer.sct.embrapa.br:article/6620Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-08-11T19:11:09Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
