ap?s renova??o de sistemas agrossilvipastoris com eucalipto. O experimento foi conduzido na
Universidade Federal de Vi?osa, MG, em um sistema agrossilvipastoril no in?cio de degrada??o do pasto.
Utilizou-se o delineamento experimental em blocos completos casualizados, com tr?s repeti??es e os tratamentos
consistiram do arranjo fatorial (3x2)+1, sendo fator A: cultivo de brachiaria brizantha cv. Marandu (capimmarandu)
com dois h?bridos de milho (BM207, com folhas planiformes e BM502, com folhas eretas) e o capimmarandu
em sistema silvipastoril e o fator B os dois espa?amentos entre ?rvores de eucalipto (12x2 e 12x4 m), e
a testemunha em pleno sol (monocultivo). As avalia??es foram aos 90 e 150 dias ap?s colheita do milho,
determinando a massa seca das l?minas foliares verdes (%LFV) e colmos verdes (%CV). A composi??o
morfol?gica da Brachiaria brizantha cv. Marandu ? alterada nos sistemas que combinam h?bridos de milho de
arquitetura foliar ereta e espa?amentos entre ?rvores maiores (12x4), com maior porcentagem de laminas
foliares. Os sistemas agrossilvipastoris s?o uma alternativa potencial a recupera??o de sistemas degradados,
melhorando a composi??o morfol?gica do pasto.ABSTRACT
It was aimed to evaluate the morphological composition of marandugrass in establishing marandugrass pastures
after renovation of agroforestry systems with eucalyptus. The experiment was conducted at the Federal
University of Vi?osa, in Minas Gerais, in an agrosylvopastoral system at the beginning of pasture degradation.
We used the experimental design in randomized complete block, with three replications and the treatments
consisted of a factorial arrangement (3x2)+1, factor A being: cultivation of Brachiaria brizantha cv. Marandu
(marandugrass) with two corn hybrids (BM207, with flat leaves and BM502, with erect leaves) and
marandugrass in silvopastoral system and factor B: two spacing between eucalyptus trees (12x2 and 12x4
meters), and the witness in full sun (monoculture).The evaluations were at 90 and 150 days after corn harvest,
determining the dry mass of green leaf blades (% GLB) and green culms (% GC). Morphological composition of
Brachiaria brizantha cv. Marandu changes in systems that combine corn hybrids with erect leaf architecture and
spacings between larger trees (12x4) with highest percentage of leaf blades. The agroforestry systems are a
potential alternative for recovering degraded systems, improving the morphological composition of the pasture
