Resumo: The deferred pasture structure determines the consumption and performance of grazing animals and, in addition, can be influenced by the duration of the deferment period and nitrogen (N) fertilisation. The objective of this work was to evaluate the structural characteristics of Brachiaria brizantha syn. Urochloa brizantha cv. Piatã (piatã palisadegrass) deferred for two periods (79 and 127 days) and with four N doses (0, 40, 80 and 120 kg ha-1) in the Zona da Mata of Minas Gerais, Brazil. The experimental design involved complete randomised blocks and a subdivided plot scheme, with three replications. The 127-day period of deferment resulted in a higher forage mass, falling index, stem percentage and density, but a lower number of tillers, percentage and volumetric density of live leaf blade. The N dose increment, in general, worsened the structural characteristics of the piatã palisadegrass deferred for 127 days. However, with the 79-day period, the N fertilisation increased the volumetric density of live leaf blades and reduced the stem percentage in the forage mass. As a preliminary recommendation, piatã palisadegrass can be deferred for 79 days and fertilised with up to 90 kg ha-1 of N in the region of Zona da Mata de Minas Gerais, Brazil.

O objetivo com este trabalho foi avaliar as características estruturais da Brachiaria brizantha syn. Urochloa brizantha cv. Piatã (capim-piatã) diferida por dois períodos (79 e 127 dias) e com quatro doses de nitrogênio (0, 40, 80 e 120 kg ha-1) na Zona da Mata de Minas Gerais, Brasil. O experimento foi em blocos completos casualizados e em esquema de parcela subdividida, com três repetições. O período de 127 dias de diferimento resultou em maiores massa de forragem, índice de tombamento, porcentagem e densidade volumétrica de colmo, porém em menores número de perfilho, porcentagem e densidade volumétrica de lâmina foliar viva. O incremento da dose de N reduziu a porcentagem de lâmina foliar viva na massa de forragem do capim-piatã diferido por 127 dias. Porém, com o período de 79 dias, a adubação aumentou a densidade volumétrica de lâmina foliar viva e reduziu a porcentagem de colmo na massa de forragem. Como recomendação preliminar, o capim-piatã pode ser diferido por 79 dias e com adubação de até 90 kg ha-1 de N na região da Zona da Mata de Minas Gerais, Brasil.UEL2020-04-07info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtigo científicoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3684210.5433/1679-0359.2020v41n3p995Semina: Ciências Agrárias; Vol. 41 No. 3 (2020); 995-1006Semina: Ciências Agrárias; v. 41 n. 3 (2020); 995-10061679-03591676-546Xreponame:Semina.
