Resumo: | The growth of both crops and Brachiaria and the Picão-preto depends on the ability of these species to extract resources from the environment in which they live and, in most cases, the supply of these resources is limited. In this context, if the competitive ability of the weed is superior, it may manifest the potential for crop suppression over competing plants. Competition can be intraspecific, occurring between individuals of the same species, whether weed or not, and also interspecific, involving individuals of different species. Thus, the objective of this work was to evaluate the effects of competition between the species corn and Picão-preto and the combination of the two at different densities on the growth of Brachiaria, seeking information about the crop and weeds in order to subsidize management strategies. In this sense, the experiment was set up in a randomized block design using the 2 x 5 factorial scheme, that is, factor A representing the community 1) Urochloa brizantha (brachiaria) + corn and the community 2) Urochloa brizantha (brachiaria) + corn + Bidens pilosa. Factor B represented by 5 densities and four replications. The growth of Brachiaria was negatively affected by the two combinations tested, highlighting that in this work, Brachiaria plants competed with increasing densities of plants of the same species and increasing densities of Picão-preto plants or the combination of the two species of Picão-preto and Brachiaria. |

En este contexto, si la capacidad competitiva de la maleza es superior, puede manifestar el potencial de supresión de cultivos sobre las plantas competidoras. La competencia puede ser intraespecífica, ocurriendo entre individuos de la misma especie, sea maleza o no, y también interespecífica, involucrando individuos de diferentes especies. Así, el objetivo de este trabajo fue evaluar los efectos de la competencia entre las especies maíz y Picão-preto y la combinación de las dos en diferentes densidades sobre el crecimiento de Brachiaria, buscando información sobre el cultivo y las malezas para subsidiar las estrategias de manejo. En este sentido, el experimento se montó en un diseño de bloques al azar utilizando el esquema factorial 2 x 5, es decir, el factor A representa la comunidad 1) Urochloa brizantha (brachiaria) + maíz y la comunidad 2) Urochloa brizantha (brachiaria) + maíz + Bidens pilosa. Factor B representado por 5 densidades y cuatro repeticiones. El crecimiento de Brachiaria fue afectado negativamente por las dos combinaciones probadas, destacándose que en este trabajo, las plantas de Brachiaria compitieron con densidades crecientes de plantas de la misma especie y densidades crecientes de plantas de Picão-preto o la combinación de las dos especies de Picão-preto y Brachiaria.O crescimento, tanto das culturas quanto da braquiária e o picão-preto, depende da habilidade dessas espécies em extrair os recursos do ambiente em que vivem e, na maioria das vezes, o suprimento desses recursos é limitado. Nesse contexto, se a habilidade competitiva da planta infestante for superior poderá manifestar o potencial de supressão das culturas sobre plantas concorrentes. A competição pode ser intra-específica, ocorrendo entre indivíduos de uma mesma espécie, seja ela daninha ou não, e, também, interespecífica, envolvendo indivíduos de espécies diferentes. Dessa forma, objetivou-se com esse trabalho avaliar os efeitos da competição das espécies milho e picão-preto e a combinação das duas em diferentes densidades no crescimento do braquiária, buscando informações sobre a cultura e as plantas daninhas a fim de subsidiar estratégias de manejo. Nesse sentido, O experimento foi montado no delineamento de blocos casualizados utilizando-se o esquema fatorial 2 x 5, ou seja, fator A representado a comunidade 1) Urochloa brizantha (braquiária) + milho e a comunidade 2) Urochloa brizantha (braquiária) + milho + Bidens pilosa. O fator B representado por 5 densidades e quatro repetições. O crescimento da braquiária foi afetado negativamente pelas duas combinações testadas, destacando-se que nesse trabalho plantas de braquiária competia com densidades crescentes de plantas da mesma espécie e densidades crescentes de plantas de picão-preto ou a combinação das duas espécies picão-preto e braquiária.Research, Society and Development2022-10-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/3204110.33448/rsd-v11i14.32041Research, Society and Development; Vol. 11 No. 14; e387111432041Research, Society and Development; Vol. 11 Núm. 14; e387111432041Research, Society and Development; v. 11 n. 14; e3871114320412525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/32041/30459Copyright (c) 2022 Josiane Costa Maciel; Evander Alves Ferreira; Tayna Sousa Duque; Brenda Thaís Barbalho Alencar; Regynaldo Arruda Sampaio; Maria Sebastiana Carmindo da Silva; Cássia Michelle Cabralhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessMaciel, Josiane CostaFerreira, Evander Alves Duque, Tayna Sousa Alencar, Brenda Thaís BarbalhoSampaio, Regynaldo ArrudaSilva, Maria Sebastiana Carmindo da Cabral, Cássia Michelle2022-11-08T13:36:27Zoai:ojs.pkp.sfu.ca:article/32041Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:48:10.226261Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
