Resumo: | Molybdenum (Mo) is a micronutrient that plays a fundamental role in the assimilation of nitrogen (N) in plants, and top-dressing N fertilization associated with different forms of molybdenum application can increase the yield and physiological potential of wheat seeds. The objective of this study was to evaluate the yield and physiological potential of wheat seeds treated with different forms of Mo application associated with N fertilization. The experiment was performed using the wheat cultivar CD150 in randomized blocks in split plots, with four replicates. Plots were evaluated for four forms of Mo application: 0 g ha-1 of Mo, seed treatment with 40 g ha-1 of Mo, foliar treatment with 40 g ha-1 of Mo, and seed + foliar treatment each at 20 g ha-1. In the subplots, four N rates (0, 30, 60, and 90 kg ha-1 N) were applied at the start of the tillering phase. We evaluated the following parameters: seed yield, mass of one thousand seeds, germination, first germination count, seedling root and shoot length, electrical conductivity, seedling emergence in sand, emergence speed index, and crude and soluble protein contents. The yield of wheat seeds increased with increasing rates of N in the top-dressing. Nitrogen fertilization associated with different forms of Mo application did not interfere with the crude and soluble protein contents or with any of the parameters related to the physiological potential of wheat seeds. |

Objetivou-se avaliar a produção e o potencial fisiológico de sementes de trigo submetido a diferentes formas de aplicação de Mo associadas à adubação nitrogenada de cobertura. O experimento foi conduzido com a cultivar CD150, sob o delineamento experimental de blocos casualizados em parcelas subdivididas, com quatro repetições. Nas parcelas foram avaliadas quatro formas de aplicação de Mo (0 g ha-1 de Mo; 40 g ha-1 de Mo no tratamento de sementes; 40 g ha-1 de Mo no tratamento foliar e 20 g ha-1 de Mo no tratamento de semente + 20 g ha-1 de Mo no tratamento foliar). Nas subparcelas, foram aplicadas quatro doses de N em cobertura (0, 30, 60 e 90 kg ha-1 de N), na fase de perfilhamento. Foram avaliados: produtividade de sementes, massa de mil sementes, germinação, primeira contagem de germinação, comprimento de parte aérea e de raiz de plântulas, condutividade elétrica, emergência de plântulas em areia, índice de velocidade de emergência e os teores de proteínas bruta e solúvel das sementes. A produtividade de sementes de trigo aumenta com o incremento das doses de N em cobertura. A fertilização nitrogenada, as diferentes formas de aplicação de Mo e a associação entre esses fatores não interferem nos teores de proteínas bruta e solúvel ou no potencial fisiológico das sementes de trigo.UEL2018-02-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/2923410.5433/1679-0359.2018v39n1p67Semina: Ciências Agrárias; Vol. 39 No. 1 (2018); 67-76Semina: Ciências Agrárias; v. 39 n. 1 (2018); 67-761679-03591676-546Xreponame:Semina.
