Resumo: This research aimed to evaluate the dry matter yield, structural composition and nutritive characteristics of diploid and tetraploid annual ryegrass cultivars on different phenological development to haymaking on lowland soils. The experimental design was developed based on randomized blocks with split plots, four cultivars of annual ryegrass (BRS Ponteio and FEPAGRO São Gabriel, diploid; INIA Escorpio and KLM 138, tetraploid), and three phenological crop phases (vegetative, pre-blossoming and blossoming). Were evaluated, dry matter yield, leaf:stem ratio, leaf weight ratio, tiller population density, specific leaf area, crude protein, neutral detergent fiber, and acid detergent fiber. All data were submitted to analysis of variance and the means were compared by Tukey-Kramer test (p< 0,05). Highest forage mass is obtained with harvest in blossoming stage. Tetraploid cultivars present better leaf proportion and higher content of crude protein during vegetative stage. The decrease the in concentration of protein with the change of phenological stage is less evident on diploid cultivars. The vegetative stage enables harvest forage with high nutritional value, with lower production of biomass.

O delineamento experimental foi de blocos ao acaso, com parcelas divididas, com quatro cultivares de azevém anual (BRS Ponteio e FEPAGRO São Gabriel, diploides; INIA Escorpio e KLM 138, tetraploides) e três estádios fenológicos (vegetativo, pré-florescimento e florescimento). Foram avaliadas: rendimento de matéria seca, relação folha/colmo, razão de peso foliar, densidade populacional de perfilhos, área foliar específica, proteína bruta, fibra em detergente neutro e fibra em detergente ácido. Os dados foram submetidos à análise de variância e as médias comparadas pelo teste Tukey-Kramer (p <0,05). A maior massa de forragem é obtida com a colheita no estádio de florescimento. As cultivares tetraploides apresentam melhor proporção foliar e maior teor de proteína bruta durante o período vegetativo. A diminuição na concentração de proteína, com a mudança de estádio fenológico é menos evidente nascultivares diploides. O estágio vegetativo possibilita a colheita de forragem com alto valor nutricional, mas com menor produção de biomassa.EDUFU2018-10-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/3940510.14393/BJ-v34n5a2018-39405Bioscience Journal ; Vol. 34 No. 5 (2018): Sept./Oct.; 1232-1238Bioscience Journal ; v. 34 n. 5 (2018): Sept./Oct.; 1232-12381981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/39405/24211Brazil; ContemporaryCopyright (c) 2018 Olmar Antônio Denardin Costa, Otoniel Geter Lauz Ferreira, Jamir Luís Silva da Silva, Ana Carolina Fluck, Alexsandro bahr Kröning, Lucas Vargas Oliveira, Régis Antonio Teixeira Coelho, William Cardinal Brondanihttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessCosta, Olmar Antônio DenardinFerreira, Otoniel Geter LauzSilva, Jamir Luís Silva daFluck, Ana CarolinaKröning, Alexsandro bahrOliveira, Lucas VargasCoelho, Régis Antonio TeixeiraBrondani, William Cardinal2022-02-10T11:37:55Zoai:ojs.www.seer.ufu.br:article/39405Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-02-10T11:37:55Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false
