Resumo: | The objective of this study was to evaluate the effects sowing systems and fertilizer application systems on the incidence of weeds and on yield components in soybean crops. Two experiments were conducted in soils with different fertility levels. An experimental design in split-plot was used; the plots consisted of four sowing systems: crossed sowing (0.45×0.45 m), and spacings between rows of 0.35 m, 0.175 m, and 0.45 m; and the subplots consisted of fertilizer application systems: application in the sowing row, broadcast fertilizer application at sowing, and no fertilizer application. The variables evaluated were: grain yield, 1000-grain weight, and weed incidence at 30 and 50 days after sowing (DAS). The weed incidence at 30 DAS was lower when using spacing between rows of 0.45 m, which was correlated with the lower turning of the soil surface layer. The plant spacing between rows of 0.175 m resulted in a lower competition with weeds at 50 DAS and in a higher shading, generating higher grain yields. The fertilizer application in the sowing row resulted in a higher grain yield and 1000-grain weight. The sowing system affects the weed population dynamics, which directly affects the grain yield of soybean crops. |

Este estudo teve por objetivo avaliar os efeitos de sistemas de semeadura e de aplicação de fertilizantes sobre a incidência de plantas daninhas e componentes de rendimento na cultura da soja. Dois experimentos foram realizados em áreas com níveis distintos de fertilidade. O delineamento experimental utilizado foi blocos ao acaso em parcelas subdivididas, o tratamento principal foi quatro sistemas de semeadura, sendo: sistema de semeadura cruzada (0,45x0,45 m); sistema de espaçamento entre linha reduzido de 0,35 m, 0,175 m e 0,45 m. Como subparcelas foram três sistemas de aplicação de fertilizantes, sendo: aplicado na linha de semeadura, lanço no momento da semeadura e sem aplicação de fertilizante. As variáveis analisadas foram: produtividade, massa de mil grãos e incidência de plantas daninhas aos 30 e 50 dias após a semeadura (DAS). Nos 30 DAS, a incidência foi menor no espaçamento entre linhas 0,45 m, fato correlacionado com o menor revolvimento da camada superficial do solo. O arranjo de planta no espaçamento entre linha de 0,175 m proporcionou menor competição entre plantas daninhas aos 50 DAS e maior sombreamento, resultando em maior rendimento de grãos. A aplicação do fertilizante na linha causou maior rendimento e massa de mil grãos. O sistema de semeadura afeta a dinâmica populacional de plantas daninhas que teve influencia direta no rendimento da cultura da soja.Universidade Federal Rural do Semi-Árido2020-05-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/829710.1590/1983-21252020v33n201rcREVISTA CAATINGA; Vol. 33 No. 2 (2020); 281-286Revista Caatinga; v. 33 n. 2 (2020); 281-2861983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/8297/10197Copyright (c) 2020 Revista Caatingainfo:eu-repo/semantics/openAccessRafain, Eliakin FredericoGubiani, João EdsonRosa, David Peres daNunes, Anderson Luis2023-07-21T17:20:12Zoai:ojs.periodicos.ufersa.edu.br:article/8297Revistahttps://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:2024-04-29T09:46:38.601188Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true |
