RESUMO
Os objetivos deste estudo foram avaliar as características morfogênicas e estruturais e o acúmulo de forragem do capim-marandu, submetido a três alturas de pastejo, sob lotação contínua. O delineamento experimental foi de blocos completos casualizados, com duas repetições e três alturas 15; 30 e 45cm. O pasto manejado com 15cm de altura apresentou as maiores taxa de aparecimento de folhas e densidade de perfilhos basilares. O acúmulo de forragem foi semelhante entre as alturas de pastejo. Com base nas características da planta, o capim-marandu pode ser utilizado entre 15 e 45cm de altura do dossel.
ABSTRACT
The objectives of this study were to evaluate the morphological and structural characteristics and the herbage accumulation, in (Brachiaria brizantha cv. 'Marandu') marandu palisadegrass pastures subjected to three grazing heights under continuous stocking. It was used a randomized block design, with two replicates and three sward heights 15, 30 and 45cm. The biggest leaf appearance and the smallest basal tiller densities decreased were found in 15cm pasture The herbage accumulation was similar among the pastures managed with different grazing intensities. The marandu palisadegrass presents high management flexibility, and may be utilized between 15 and 45cm sward height.
