Resumo: An experiment was established in Castro, Paraná State, with the objective of evaluating the effect of trinexapac-ethyl applied at different times and in varied nitrogen rates, on the Avante wheat cultivar. The experimental design consisted of completely randomized blocks, in a 4x4 factorial scheme, with four repetitions. The treatments consisted of 100 g ha-1 of trinexapac-ethyl applied between the first and second visible node, second and third visible node, sequential application of half the rate between first and second visible nodes and half between second and third visible nodes, and control (without application). The nitrogen rates were 90, 135, 180 and 225 kg ha-1. The study evaluated the stand; tiller number and plant height; stem diameter; lodging; nitrogen content in leaves; yield and components. Trinexapac-ethyl reduced plant height and lodging percentage. The application between the first and second visible nodes and between the second and third visible nodes promoted improved yield. The rise in the nitrogen rate increased the nutrient content in the plant and caused greater lodging, but without effect in the yield components and productivity.

Os tratamentos constaram da aplicação de 100 g ha-1 de trinexapac-ethyl entre o primeiro e o segundo nó visível, o segundo e o terceiro nó visível, aplicação sequencial de metade da dose entre o primeiro e o segundo nó visível e metade entre o segundo e o terceiro nó visível e testemunha sem aplicação. As doses de nitrogênio em cobertura foram 90, 135, 180 e 225 kg ha-1. Foram avaliados estande, número de perfilhos, altura de plantas, diâmetro do colmo, acamamento, teor de nitrogênio nas folhas, componentes da produção e produtividade. O trinexapac-ethyl reduziu a altura das plantas e a porcentagem de acamamento. A aplicação entre o primeiro e o segundo nó visível e entre o segundo e o terceiro nó visível promoveram aumento da produtividade de grãos. O aumento da dose de nitrogênio aumentou o teor do nutriente na planta e causou maior acamamento, mas sem efeitos nos componentes de produção e na produtividade.Universidade Estadual de Maringá2009-06-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/104810.4025/actasciagron.v31i3.1048Acta Scientiarum.
