Abstract	Se determino el rendimiento y calidad del forraje en un sistema silvopastoril con Leucaena leucocephala cv . Cunningham (5000 arboles ha -1 ) asociado con Megathyrsus maximus cv . Tanzania, en cuatro intervalos de descanso (20, 30, 40 y 50 d), en dos epocas (lluvias y seca) en clima calido Subhumedo. Los tratamientos se distribuyeron aleatoriamente a las unidades experimentales (12 parcelas, 24 m 2 c/u) y se evaluo el rendimiento y calidad nutritiva del forraje en la epoca humeda (agosto-octubre, 2014) y seca (marzo-abril, 2015). La graminea aporto la mayor proporcion de forraje a la biomasa disponible (80 vs . 20%) y se produjo mas biomasa total a 50 dias en lluvias (5300 kg MS ha -1 ) y seca (1620 kg MS ha -1 ); en lluvias, la proteina cruda (PC) de los arboles aumento gradualmente a 22% (P 0.05); fibra detergente neutro (FDN) se mantuvo (44%) (P>0.05) y fibra detergente acido (FDA) aumento (25%) (P<0.05) a 50 dias, mientras digestibilidad in vitro de la materia seca (DIVMS) disminuyo (49%) (P<0.05). En la graminea, la PC (10%) (P<0.001) y DIVMS (58 %) se mantuvieron hasta 40 dias y despues declinaron (P<0.03), aunque FDN y FDA aumentaron significativamente a 50 dias, en ambas epocas. la asociacion L. leucocephala y M. maximus, alcanza su mayor produccion entre 40-50 dias, con mejor calidad nutritiva de la graminea a 40 dias, que se puede compensar con el valor nutritivo del follaje de los arboles hasta los 50 dias de descanso, independientemente de la epoca.
