Resumo: | Weed interference is a factor that limits the productivity of beans and, among these, hairy beggarticks is one of the main species competing with the crop for environmental resources. Thus, the aim of this study is to evaluate the competitive ability of black bean cultivars (BRS Campeiro, IPR Uirapuru, SCS204 Predileto and BRS Supremo) in the presence of a biotype of hairy beggarticks. The experimental design is a completely randomized block with four replications. Treatments were arranged in a replacement series, consisting of a proportion of the crop and the hairy beggarticks: 100:0; 75:25; 50:50: 24:75, and 0:100, which corresponds to 40:0, 30:10, 20:20, 10:30, and 0:40 plant pots1. We accomplished competitive analysis through diagrams applied to the replacement series, as well as using relative competitive indices. The leaf area and shoot dry mass were evaluated at 40 days after emergence of the species. There was competition between bean cultivars and hairy beggarticks for the same environmental resources, causing negative interference in the growth of the species, independent of the proportion of plants. Bean cultivars had a lower relative loss by reducing the morphological variables of the hairy beggarticks, thereby demonstrating superiority in its competitive ability in relation to the weed. Interspecific competition is less damaging than intraspecific competition for both species. |

Assim sendo, objetivou-se com este trabalho, avaliar a habilidade competitiva de cultivares de feijão do tipo preto (BRS Campeiro, IPR Uirapuru, SCS204 Predileto e BRS Supremo) na presença de biótipo de picão-preto. O delineamento utilizado foi o de blocos casualizados, com quatro repetições. Os tratamentos foram arranjados em série substitutiva e constituíram-se de proporções da cultura e de picão-preto: 100:0; 75:25; 50:50: 24:75 e 0:100, o que corresponde a 40:0, 30:10, 20:20, 10:30 e 0:40 plantas vaso-1. A análise da competitividade foi efetuada por meio de diagramas aplicados a experimentos substitutivos, mais uso de índices de competitividade relativa. Avaliou-se a área foliar e a massa seca da parte aérea aos 40 dias após a emergência das espécies. Houve competição pelos mesmos recursos do meio entre as cultivares de feijão e o picão-preto, ocasionando interferência negativa no crescimento das espécies, independentemente da proporção de plantas. As cultivares de feijão apresentaram menor perda relativa ao reduzirem as variáveis morfológicas do picão-preto e demonstram possuir superioridade na habilidade competitiva em relação à planta daninha. A competição interespecífica é menos prejudicial para ambas as espécies envolvidas do que a competição intraespecífica.Universidade Federal Rural do Semi-Árido2017-06-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/594910.1590/1983-21252017v30n405rcREVISTA CAATINGA; Vol. 30 No. 4 (2017); 855-865Revista Caatinga; v. 30 n. 4 (2017); 855-8651983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/5949/pdfGalon, LeandroTrevisol, RicardoForte, Cesar TiagoTironi, Siumar PedroReichert Júnior, Francisco WilsonRadunz, André Luizinfo:eu-repo/semantics/openAccess2023-07-20T11:28:39Zoai:ojs.periodicos.ufersa.edu.br:article/5949Revistahttps://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:2024-04-29T09:46:25.566515Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true |
