Resumo: | Morphological characteristics, dry matter production, and nutritional values of winter forage and grains were evaluated. This study was conducted from April 24, 2012 to November 7, 2013 in the Western Paraná State University (UNIOESTE), Marechal Cândido Rondon, Brazil. Pastures under one grazing and non-grazing conditions were evaluated under 120 kg N ha-1 fertilization split into two 60 kg N ha-1 treatments. Two pastures received 40 kg N ha-1 three times. IPR 126 oat, BRS Tarumã wheat, and IPR 111 triticale were the test crops. Topdressing with 40 or 60 kg N ha-1 did not change morphological characteristics until 60 d after sowing. Pastures under non-grazing that received 120 kg N ha-1 treatments were taller than the controls, whereas those under grazing that received 80 or 120 kg N ha-1 presented with higher leaf production than did the controls. Total average dry matter (DM) production in 2012 and 2013 was, respectively, 5,275 kg ha-1 and 6,270 kg ha-1 for oat, 3,166 kg ha-1 and 7,423 kg ha-1 for wheat, and 4,552 kg ha-1 and 7,603 kg ha-1 for triticale. Split N fertilization did not cause differences in the levels of crude protein (CP), neutral detergent fiber (NDF), and acid detergent fiber (ADF) in the forage. Nevertheless, increases in in vitro dry matter digestibility (IVDMD) were observed in oat and wheat receiving 60 kg N ha-1 during the first graze. IVDMD did not change in oat, wheat, and triticale forages receiving 80 or 120 kg N ha-1 during the second graze. Grazing did not affect the nutritional values of wheat and triticale grains, but reduced those of oat. Therefore, the results of the present study suggest that grazing lengthens the crop cycles, and so allow the staggered sowing of summer crops. |

O trabalho foi desenvolvido de 24/04/2012 a 07/11/2013 na UNIOESTE. Foram avaliados os manejos sem pastejo e um pastejo (ambos com 120 kg ha-1 de N em duas aplicações de 60 kg ha-1) e dois pastejos com três aplicações de N de 40 kg ha-1 nas culturas da aveia IPR 126, trigo BRS Tarumã e triticale IPR 111. A adubação em cobertura das doses de 40 ou 60 kg ha-1 de N não alteraram as características morfológicas até 60 dias após a semeadura. As parcelas sem pastejo e com 120 kg ha-1 de N em duas doses de 60 kg ha-1 de N cada tiveram, em 2012 e 2013, maior altura, enquanto as pastejadas com 80 ou 120 kg ha-1 de N tiveram maior proporção de folhas. A média da produção total de MS em 2012 e 2013 respectivamente foi de: aveia 5275 e 6270 kg ha-1; trigo 3166 e 7423 kg ha-1; triticale 4552 e 7603 kg ha-1. Na forragem não foram observadas diferenças nos teores de PB, FDN e FDA em função do parcelamento de N, mas 60 kg ha-1 de N aumenta a DIVMS na aveia e trigo no primeiro pastejo e 80 ou 120 kg ha-1 de N não alteram a digestibilidade da forragem das três culturas no segundo pastejo. O pastejo não altera o valor nutricional de grãos de trigo e triticale, mas reduz nos grãos de aveia. Os ciclos das culturas são diferentes e aumenta com os pastejos e por isso permitem a semeadura escalonada com as culturas de verão.UEL2017-06-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Empírica de Campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/2632010.5433/1679-0359.2017v38n3p1483Semina: Ciências Agrárias; Vol. 38 No. 3 (2017); 1483-1500Semina: Ciências Agrárias; v. 38 n. 3 (2017); 1483-15001679-03591676-546Xreponame:Semina.
