| description | The aim of this study was to evaluate the development and quality of ryegrass in an understorey of angico-vermelho in a silvopastoral system. The experimental design was a complete randomized block, with a 2x6 factorial, being two systems of production (full sunlight and silvopastoral) and six times of harvest (15, 30, 45, 60, 75 and 90 days after ryegrass emergence), with three replications. The interception of the photosynthetically active solar radiation, average air temperature, dry matter, leaf area and protein content were evaluated. According to the analysis of variance, the interaction between production system and time of harvest resulted in significant differences for dry matter and the protein content and leaf area resulted in differences only according to the harvest time. The development of ryegrass is influenced by shading, when grown in this study conditions. The shade provided by angico-vermelho reduces the amount of ryegrass dry matter of ryegrass, but this reduction does not limit the use of the specie to compose a silvopastoral system. The total protein content and leaf area of ryegrass are not influenced by the light restriction. |

The experimental design was a complete randomized block, with a 2x6 factorial, being two systems of production (full sunlight and silvopastoral) and six times of harvest (15, 30, 45, 60, 75 and 90 days after ryegrass emergence), with three replications.

O objetivo deste trabalho foi avaliar o desenvolvimento e qualidade do azevém no sub-bosque de angico-vermelho em sistema silvipastoril. O delineamento experimental utilizado foi de blocos completos casualizados, em esquema fatorial 2x6, ou seja, dois sistemas de produção (pleno sol e silvipastoril) e seis cortes (15, 30, 45, 60, 75 e 90 dias após a emergência do azevém), com três repetições. Avaliou-se a interceptação de radiação solar fotossinteticamente ativa incidente, temperatura média do ar, massa de matéria seca, área foliar e teor de proteína bruta. De acordo com a análise de variância, a interação entre sistema de produção e corte demonstrou diferença significativa para a massa de matéria seca, já o teor de proteína bruta e área foliar demonstraram diferença apenas em função dos cortes realizados. O desenvolvimento do azevém é influenciado pelo sombreamento, quando cultivado no sub-bosque de angico-vermelho emsistema silvipastoril. O sombreamentoprovocado pelo angico-vermelho reduz o rendimento da massa de matéria seca do azevém, porém essa redução não limita o uso da espécie para compor um sistema silvipastoril. O teor de proteína bruta e a área foliardo azevém não são influenciados pela restrição luminosa. 2015-12-29 2022-03-21T20:07:37Z 2022-03-21T20:07:37Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion https://comunicatascientiae.com.br/comunicata/article/view/1079 10.14295/cs.v6i4.1079 http://biblioteca-repositorio.clacso.edu.ar/handle/CLACSO/77762 por https://comunicatascientiae.com.br/comunicata/article/view/1079/363 Copyright (c) 2016 Janine Pilau, Elvis Felipe Elli, Maicon Nardino, Cleiton Korcelski, Denise Schmidt, Braulio Otomar Caron application/pdf Federal University of Piauí Comunicata Scientiae; Vol. 6 No. 4 (2015); 437-444 Comunicata Scientiae; v. 6 n. 4 (2015); 437-444 2177-5133 2176-9079 |
