Resumo: | An experiment was carried out in red latosol, emphasizing border effect Five cultivars of rice were used (‘IAC-25', 'Tainan', 'IET-1444', 'Fernandes', and ‘IRAT-13’), seeded in rows of 0.50 m width with 50 seeds per linear meter, laid out in blocks by chance, with four repetitions. The harvest was made by positions differentiated within the plot and the analyses in the scheme of subdivided plots were made. A strong plot and border effect on the production of grains was verified in all the cultivars, while the lateral border effect was seen only in the 'Fernandes' and 'IRAT-13' cultivars. Plant height was affected in any of the situations. It was concluded that it is necessary to use and borders with 1 m of distance from each extremity, and lateral borders with two rows. |

Foi conduzido um experimento em Latossolo Vermelho-Amarelo, focalizando efeito de bordadura. Foram usadas cinco cultivares de arroz (‘IAC-25', 'Tainan', 'IET-1444', 'Fernandes' e 'IRAT-13'), semeadas em linhas distanciadas de 0,50 m e com 50 sementes por metro linear ; dispostas em blocos ao acaso, com quatro repetições. A colheita foi feita por posições diferenciadas dentro da parcela e foram efetuadas as análises no esquema de parcelas subdivididas. Verificou-se forte efeito das cabeceiras das parcelas sobre a produção de grãos em todas as cultivares, enquanto que o efeito de bordadura lateral manifestou-se, apenas, nas cultivares 'Fernandes' e 'IRAT-13'. A altura das plantas não foi afetada significativamente em nenhuma das situações. Concluiu-se ser necessário o uso de bordaduras de cabeceira com 1 m de distância de cada extremidade, e de bordaduras laterais com duas linhas.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraZimmermann, Francisco José Pfeilsticker2014-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16569Pesquisa Agropecuaria Brasileira; v.15, n.3, mar. 1980; 297-300Pesquisa Agropecuária Brasileira; v.15, n.3, mar. 1980; 297-3001678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/16569/10845info:eu-repo/semantics/openAccess2014-04-15T19:32:36Zoai:ojs.seer.sct.embrapa.br:article/16569Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-15T19:32:36Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
