(one cultivar). The most productive treatments were: Paspalum notatum entrie EEL 10162 (CP 13,9%, IVDOM 49% and 20559 kg/ha DM); Axonopus sp. entries Missioneira Gigante (CP 12%, IVDOM 61,8% and 18469 kg/ha DM) and Taió (CP 14,5%, IVDOM 53,1% and 19077 kg/ha DM); Hemarthria altissima entries IAPAR — 35 — Roxinha (CP 10,8%, IVDOM 44,8% and 17068 kg/ha DM), PI 349798 (CP 11,7%, IVDOM 56,9% and 16273 kg/ha DM), PI — HM — 365509 (CP 11,4%, IVDOM 55,5% and 15466 kg/ha DM), and IAPAR — 36 — Flórida (CP 11,2%, IVDOM 60,2% and 14659 kg/ha DM); Cynodon sp. cultivar Tifton 85 (CP 14,1%, IVDOM 50,2% and 19784(CP 13,9%, IVDOM 49% and 20559 kg/ha DM) kg/ha DM).
