Resumo: A field experiment was carried out at Seropédica, state of Rio de Janeiro, Brazil, to evaluate the effects of soil solarization on purple nutsedge (Cyperus rotundus) weed population and on productivity of vegetable crops under organic cultivation. Solarization was accomplished by covering the soil surface with transparent polyethylene sheets (50 mm) for a period of 210 days. The mean temperature at 0-10 cm soil layer was about 23% higher than that of unsolarized plots. Following plastic removal the area was planted with carrot (Daucus carota 'Brasília'), cabbage (Brassica oleracea var. capitata 'Astrus'), garden beet (Beta vulgaris 'Tall Top Early Wonder'), and dwarf greenbean (Phaseolus vulgaris 'Alessa'). In general, soil solarization reduced purple nutsedge population by 59%. There was a significant increase in yields of carrot (28%), cabbage (34%), beet (37%), and greenbean (32%) when compared to unsolarized plots. Biological nitrogen fixation, as judged by greenbean nodulation, was not affected by solarization but the soil nematode population was considerably reduced.

A solarização correspondeu à cobertura do solo com polietileno transparente (50 mm) por um período de 210 dias. Houve um aumento da temperatura média da camada superficial do solo (0-10 cm) da ordem de 23%, em relação ao das parcelas não-solarizadas. Após a retirada do plástico, cultivaram-se: cenoura (Daucus carota 'Brasília'), repolho (Brassica oleracea var. capitata 'Astrus'), beterraba (Beta vulgaris 'Tall Top Early Wonder') e vagem-anã (Phaseolus vulgaris 'Alessa'). Em termos gerais, a solarização reduziu em 59% a reinfestação pela tiririca. Nas parcelas solarizadas, houve significativo incremento das produtividades de cenoura (28%), vagem (32%), beterraba (37%) e repolho (34%). A fixação biológica do nitrogênio, a julgar pela nodulação da vagem, não foi afetada pela solarização, mas a população de nematóides do solo sofreu considerável redução.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraRicci, Marta dos Santos FreireAlmeida, Dejair Lopes deFernandes, Maria do Carmo AraújoRibeiro, Raul de Lucena DuarteCantanheide, Maria Cláudia dos Santos2000-11-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6009Pesquisa Agropecuaria Brasileira; v.35, n.11, nov. 2000; 2175-2179Pesquisa Agropecuária Brasileira; v.35, n.11, nov. 2000; 2175-21791678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6009/3113info:eu-repo/semantics/openAccess2014-08-20T17:01:41Zoai:ojs.seer.sct.embrapa.br:article/6009Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-08-20T17:01:41Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
