Resumo: This research work aimed to determine the total period of interference of weeds prevention of lettuce cultivar Solaris. The experiment was conducted in Universidade Estadual de Londrina, in the period of autumn/ winter of 2008. The lettuce crop remained free from weed interference from emergence up to 0, 10, 20, 30, 40, 50 e 60 days. The experiment was arranged in a randomized block design with four replications. The weed community was composed by Bidens pilosa, Amaranthus hybridus, Oxalis corniculata, Euphorbia heterophylla, Spinacia oleracea, Commelina benghalensis e Lepidium virginicum. It was determined dry and fresh matter of weeds, and number of lettuce leaves. Assuming a tolerance of 5% for crop production decrease, it was verified that the total period of interference prevention (TPIP) occurred up to 21 days after transplanting. Weed interference throughout the crop cycle reduced 25% of its yield.

O experimento foi instalado na Universidade Estadual de Londrina, no período de outono/ inverno de 2008. A cultura permaneceu livre da interferência das plantas daninhas desde o transplante até: 0, 10, 20, 30, 40, 50 e 60 dias. O delineamento utilizado foi o de blocos casualizados com quatro repetições. A comunidade infestante da área foi composta principalmente de Bidens pilosa, Amaranthus hybridus, Oxalis corniculata, Euphorbia heterophylla, Spinacia oleracea, Commelina benghalensis e Lepidium virginicum. As massas seca e fresca das plantas daninhas e o número de folhas da cultura foram determinados. Admitindo-se 5% de tolerância na redução da produtividade da cultura, o período total de prevenção à interferência (PTPI) ocorreu 21 dias após o transplante. A interferência das plantas daninhas durante todo o ciclo de vida da alface reduziu a produtividade em 25%.UEL2011-02-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Empírica de Campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/334710.5433/1679-0359.2010v31n4Sup1p1299Semina: Ciências Agrárias; Vol. 31 No. 4Sup1 (2010); 1299-1304Semina: Ciências Agrárias; v. 31 n. 4Sup1 (2010); 1299-13041679-03591676-546Xreponame:Semina.
