Conteúdo: | Forage species diversification reduces risk associated with forage?livestock production. In the Amazon biome, an alternative is needed to ?Marandu? palisadegrass [Urochloa brizantha (Hochst. ex A. Rich.) R.D. Webster] because of Marandu death syndrome. Our objective was to compare herbage accumulation (HA), canopy characteristics, and nutritive value of Marandu with two alternative grasses, ?Guará? (Paspalum regnellii Mez) and ?Tupi? [Urochloa humidicola (Rendle) Morrone & Zuloaga]. During 2 yr, grasses were clipped to a 12-cm stubble height every 28 (rainy season) or 42 d (dry season). Annual HA did not differ across years for Guará (13.7 Mg dry matter [DM] ha&#8722;1) and Tupi (12.2 Mg DM ha&#8722;1); however, Marandu HA was 30% less in the second than the first year. Marandu had greatest annual HA in the first year (15.5 Mg DM ha&#8722;1), and Guará was superior to the other grasses in the second year (13.5 Mg DM ha&#8722;1). Tupi had the least leaf proportion among grasses in both rainy and dry seasons, and its leaf proportion was greater in the dry than rainy season (715 vs. 610 g kg&#8722;1). Greatest stem proportion was observed in Tupi and the least stubble mass occurred in Guará (2000 kg DM ha&#8722;1). When differences in crude protein occurred, Tupi concentrations (80?130 g kg&#8722;1) were less than either Guará (97?157 g kg&#8722;1) or Marandu (81?139 g kg&#8722;1). Overall, Tupi and Guará HA and nutritive value support their recommendation as alternatives to Marandu monoculture in Amazon forage-based livestock systems.
