Resumo: | The interference of weeds in coexistence with peanuts affects the growth and development of plants, which can cause losses of more than 80% in crop productivity. Among the main problematic weeds in the peanut production areas, there has been a significant increase in climbing plants, mainly mucuna and viola cords. Therefore, the objective of this work was to evaluate the impact of the competition of the black mucuna in the development of the plants and in the productivity of the peanut. The experiment was conducted in the field in a randomized block design, with 5 replications. The treatments consisted of six densities of black mucuna (0, 1, 2, 3, 4 and 5 plants / m2) in competition with the peanut cultivar IAC OL3. During the reproductive stages R1 to R7, evaluations of photosynthetically active radiation intercepted by weeds and peanut culture were carried out. At the end of the experimental period (130 DAS), peanuts and black mucuna were harvested manually. Then, the dry mass of the aerial part of the mucuna-negra and peanut was determined. The number and mass of the peanut pods and seeds were also determined. The data obtained were subjected to analysis of variance by the F test and the means compared by the Tukey test at the level of 5% probability. Based on the results obtained, it was found that the vegetative mass of the black mucuna, regardless of plant density, provided shading in the peanuts, reducing, on average, 90% the interception of photosynthetically active radiation by the crop, 70% the vegetative mass peanut and 76% the productivity of peanut pods and seeds. Therefore, it is concluded that the black mucuna is a very aggressive plant in competition with the peanut culture and causes serious losses in the density of one or more plants / m2. |

Entre las principales malezas problemáticas en las zonas productoras de maní, se ha observado un aumento significativo de plantas trepadoras, principalmente cuerdas de mucuna y viola. Por tanto, el objetivo de este trabajo fue evaluar el impacto de la competencia de la mucuna negra en el desarrollo de las plantas y en la productividad del maní. El experimento se realizó en campo en un diseño de bloques al azar, con 5 repeticiones. Los tratamientos consistieron en seis densidades de mucuna negra (0, 1, 2, 3, 4 y 5 plantas / m2) en competencia con el cultivar de maní IAC OL3. Durante las etapas reproductivas R1 a R7, se realizaron evaluaciones de radiación fotosintéticamente activa interceptada por malezas y cultivo de maní. Al final del período experimental (130 DAS), el maní y la mucuna negra se recolectaron manualmente. Luego, se determinó la masa seca de la parte aérea de la mucuna-negra y maní. También se determinó el número y la masa de las vainas y semillas de maní. Los datos obtenidos se sometieron a análisis de varianza mediante la prueba F y las medias se compararon mediante la prueba de Tukey al nivel de 5% de probabilidad. Con base en los resultados obtenidos, se encontró que la masa vegetativa de la mucuna negra, independientemente de la densidad vegetal, proporcionó sombreado en el maní, reduciendo, en promedio, en un 90% la interceptación de la radiación fotosintéticamente activa por parte del cultivo, en un 70% la masa vegetativa maní y 76% la productividad de las vainas y semillas de maní. Por tanto, se concluye que la mucuna negra es una planta muy agresiva en competencia con el cultivo del maní y provoca graves pérdidas en la densidad de una o más plantas / m2.A interferência de plantas daninhas em convivência com o amendoim afeta o crescimento e desenvolvimento das plantas, podendo causar perdas superiores a 80% na produtividade da cultura. Dentre as principais espécies daninhas problemáticas nas áreas de produção de amendoim, tem-se observado aumento significativo das plantas trepadeiras, principalmente, da mucuna e cordas-de-viola. Diante disso, objetivou-se com este trabalho avaliar o impacto da competição da mucuna-preta no desenvolvimento das plantas e na produtividade do amendoim. O experimento foi conduzido em campo no delineamento em blocos casualizados, com 5 repetições. Os tratamentos foram constituídos por seis densidades de mucuna-preta (0, 1, 2, 3, 4 e 5 plantas/m2) em competição com a cultivar de amendoim IAC OL3. Durante os estágios reprodutivos R1 a R7, foram realizadas avaliações da radiação fotossinteticamente ativa interceptada pelas plantas daninhas e pela cultura do amendoim. Ao final do período experimental (130 DAS), foi realizada a colheita manual do amendoim e da mucuna-preta. Em seguida, foi determinada a massa seca da parte aérea da mucuna-preta e do amendoim. Determinou-se, também, o número e massa das vagens e sementes do amendoim. Os dados obtidos foram submetidos a análise de variância pelo teste F e as médias comparadas pelo teste de Tukey ao nível de 5% de probabilidade. Com base nos resultados obtidos, verificou-se que a massa vegetativa da mucuna-preta, independente da densidade de plantas, proporcionou sombreamento no amendoim, reduzindo, em média, 90% a interceptação da radiação fotossinteticamente ativa pela cultura, 70% a massa vegetativa do amendoim e 76% a produtividade de vagens e sementes do amendoim. Diante disso, conclui-se que a mucuna-preta é uma planta bastante agressiva em competição com a cultura do amendoim e causa sérios prejuízos na densidade de uma ou mais plantas /m2.SAS2020-10-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://www.southamericansciences.com.br/index.php/sas/article/view/3910.17648/sas.v1i2.39South American Sciences; Vol. 1 Núm. 2 (2020): South American Sciences; e2039South American Sciences; v. 1 n. 2 (2020): South American Sciences; e20392675-722210.17648/sas.v1i2reponame:South American Sciencesinstname:Instituto Prosinstacron:PROSporhttps://www.southamericansciences.com.br/index.php/sas/article/view/39/27Copyright (c) 2020 South American Sciencesinfo:eu-repo/semantics/openAccessSilva, Ebson Piazentine, Ana ElizaChiconi, Leandro Aparecido Chiconida Costa, Maira Rosene Carrega, Willians César Alves, Pedro Luís da Costa Aguiar 2020-11-07T14:36:42Zoai:ojs2.southamericansciences.com.br:article/39Revistahttps://www.southamericansciences.com.br/index.php/sasPRIhttps://www.southamericansciences.com.br/index.php/sas/oaisoares-agro@hotmail.com || atenaconsultoriac@gmail.com2675-72222675-7222opendoar:2020-11-07T14:36:42South American Sciences - Instituto Prosfalse |
