Resumo: | The Brazilian livestock activity is undergoing constant evolution, and aiming at its maximum efficiency, it is necessary to have available to the animals food in quantity and quality all the year. To this end, the cultivation of winter forage is carried out. The present study aimed to evaluate the productive and qualitative agronomic traits of ryegrass forage. The experiment was a randomized block design in a 3 x 2 factorial arrangement consisting of six treatments, three plant stands (525, 1050 and 2095 plants m-2) associated with two successive cutting times (vegetative and full vegetative), and four repetitions. There was no interaction between population stand and cutting times for the variables studied. The stand of 525 plants m-2 had a higher participation of green leaves (50.52 %), higher digestibility of the whole plant dry matter (84.81 %) compared to the stands of 1.050 and 2.095 plants m-2, and dry biomass production per unit area equivalent to the others (6087, 7243 and 6989 kg ha-1, respectively). The first harvest season presented higher participation of green leaves and better leaf/stem ratio, 58.62 % and 3.41 % respectively, as well as higher digestibility of green leaves (77.26 %) and stem (80.82 %). |

O delineamento experimental foi o de blocos ao acaso, num esquema fatorial 3 x 2, composto por seis tratamentos, sendo três estandes de plantas (525, 1.050 e 2.095 plantas m2) associado a duas épocas de corte sucessivas (vegetativo e pleno vegetativo) e quatro repetições. Não ocorreu interação entre estande populacional e épocas de corte para as variáveis estudadas. O estande de 525 plantas m-2 apresentou maior participação de folhas verdes (50,52 %), maior digestibilidade da matéria seca da planta inteira (84,81 %) em relação aos estandes de 1.050 e 2.095 plantas m-2, e produção de biomassa seca por unidade de área equivalente aos demais (6.087, 7.243 e 6989 kg ha-1 respectivamente). A primeira época de colheita apresentou maior participação de folhas verdes e melhor relação folha/colmo 58,62 % e 3,41 % respectivamente, assim como maior digestibilidade das frações folhas verdes (77,26 %) e do colmo (80,82 %).UEL2020-05-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Cientificaapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3686910.5433/1679-0359.2020v41n4p1291Semina: Ciências Agrárias; Vol. 41 No. 4 (2020); 1291-1306Semina: Ciências Agrárias; v. 41 n. 4 (2020); 1291-13061679-03591676-546Xreponame:Semina.
