Resumo: Sweet potato is a promising crop in Brazil due to its potential for bioenergy production. However, little information on adequate chemical weed control is found for this crop. Thus, the objective of this work was to evaluate the effect of clomazone on 20 genotypes of sweet potato and the sensitivity of these materials to weed interference. A field experiment was conducted using an experimental design with four blocks arranged in split-plots. The sweet potato genotypes Brazlândia-Branca, Cariru-Vermelha, Princesa, Tomba-Carro-1 and UFVJM (01, 05, 06, 07, 08, 10, 14, 23, 26, 30, 35, 42, 43, 46, 48 and 49) were grown for 180 days under three weed managements (soils treated with clomazone, mechanically weeded and with no weed control). The plots consisted of the weed control methods and the subplots consisted of the sweet potato genotypes. Phytotoxicity, branch growth and yield were evaluated. Plants grown with no weed interference had larger branch length. The highest yields were found in clomazone-treated soils. Weed interference reduced 81 to 99.7% of the yield. The less susceptible genotypes to weed interference were UFVJM07, UFVJM10 and UFVJM35, and the most sensitive were Princesa and UFVJM01. The root yield of plants under chemical weed control was similar to or greater than those with mechanical weed control in 17 of the 20 genotypes evaluated.

Porém, são escassas informações acerca da adequacão do controle químico de plantas daninhas na cultura. Objetivou-se avaliar o uso de clomazone no cultivo de 20 genótipos de batata-doce e a sensibilidade dos materiais à interferência de plantas daninhas. Para isso, em condições de campo, foi delineado um experimento em quatro blocos e esquematizado em parcelas subdivididas. Os genótipos Brazlândia Branca, Cariru Vermelha, Princesa, Tomba Carro1 e UFVJM (01, 05, 06 , 07, 08, 10, 14, 23, 26, 30, 35, 42, 43, 46, 48 e 49) foram cultivados por 180 dias em solo tratado com clomazone, capinado mecanicamente ou sem o controle de plantas daninhas. As formas de controle compunham as parcelas, e os genótipos foram alocados nas subparcelas. Foi avaliada a fitointoxicação, o crescimento de ramas e a produtividade. Foi observado maior comprimento de ramas quando as plantas cresceram sem a interferencia das plantas daninhas. As maiores produtividades foram conseguidas em solo tratado com clomazone e a interferência de plantas daninhas provocou reduções de 81 a 99,7% na produtividade. Os genótipos menos sensíveis à interferência de plantas daninhas foram UFVJM07, UFVJM10 e UFVJM35, enquanto os mais sensíveis foram Princesa e UFVJM01. O controle químico proporcionou produtividade de raízes semelhante ou superior ao controle mecânico para 17 dos 20 genótipos estudados.Universidade Federal Rural do Semi-Árido2018-04-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/662210.1590/1983-21252018v31n211rcREVISTA CAATINGA; Vol. 31 No. 2 (2018); 352-359Revista Caatinga; v. 31 n. 2 (2018); 352-3591983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/6622/pdfCopyright (c) 2018 Revista Caatingainfo:eu-repo/semantics/openAccessSantos, Edson Aparecido dosAndrade Júnior, Valter Carvalho deViana, Daniel José da SilvaSantos, Albertir Aparecido dosSilva, Antônio Júlio Medina daFialho, Cíntia Maria Teixeira2023-07-20T12:49:43Zoai:ojs.periodicos.ufersa.edu.br:article/6622Revistahttps://periodicos.ufersa.edu.br/index.php/caatinga/indexPUBhttps://periodicos.ufersa.edu.br/index.php/caatinga/oaipatricio@ufersa.edu.br|| caatinga@ufersa.edu.br1983-21250100-316Xopendoar:2024-04-29T09:46:29.712351Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true
