Resumo: The agronomic traits and nutritive value of Brachiaria decumbens pasture were evaluated under three shade percentages (0.29% and 45%), provided by leguminous trees (Acacia angustissima, A. mangium, A. auriculiformis, Albizia lebbek e Gliricidia sepium), during winter, spring and summer seasons. The experimental design was randomized blocks, with three replications. The forage mass was positively influenced by shading, in spring and summer seasons. In winter, the higher forage mass was observed in full sunlight condition. The values of crude protein increased in spring with shading, but did not vary with shade percentage in winter and summer seasons. The crude protein quantity per area, obtained by product between forage mass and crude protein concentration, was higher under more intensive shading, in spring and summer seasons. Fiber detergent neutral content and in vitro dry matter digestibility did not present consistent variation with shading, in function of the strong interaction between this variable and season of the year.

Foi adotado o delineamento experimental de blocos casualizados, com três repetições. O sombreamento influenciou positivamente a massa de forragem, na primavera e no verão. No inverno, a maior massa de forragem foi obtida sob sol pleno. Os teores de proteína bruta aumentaram com o sombreamento, na primavera, mas não se modificaram em função das porcentagens de sombra, no inverno e no verão. Pelo produto da massa de forragem e o teor de proteína bruta, obtiveram-se as quantidades de proteína bruta por área, que foram maiores sob sombreamento mais intenso, na primavera e no verão. Os teores de fibra em detergente neutro e a digestibilidade in vitro da matéria seca não apresentaram tendência consistente com as porcentagens de sombreamento, em função da forte interação deste tratamento com a estação do ano. doi: 10.4336/2009.pfb.60.19Embrapa Florestas2010-02-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/42Pesquisa Florestal Brasileira; n. 60 (2009): dez.
