Two experiments were conducted to evaluate alternatives in the grasslands revegetation in poor condition. The experiment one consisted in reseeding blue grama (Bouteloua gracilis), side oat grama (Bouteloua curtipendula) and weeping lovegrass (Eragrostis curvula). Four densities were evaluated: control treatment 100% (T "1"), two 125% treatment (T "2"), three treatment 75% (T "3") and four 50% treatment (T "4 "). The variables evaluated were plant density (PD), plant height (PH) and tiller diameter (TD). In the second experiment was evaluated different seed beds, range restored (SB-1), disc harrow (SB-2) and roller aerator (SB-3), using a grass mix. Dry matter production was estimated. Statistical analysis included seed density and species as fixed effects and their interaction, using a 3 x 4 factorial completely randomized blocks and five replicates per treatment. For the experiment conducted two ANOVA and comparison of means. In both experiments was used the GLM procedure of SAS. The number of plants was higher (104) in Weeping lovegrass (P ? 0.001) with respect to side oats grama  (21 and 17 plants/m2). The plant height was higher (14.2 cm) in weeping lovegrass (P ? 0.001) with respect to the side oats grama (1.3 and 1.1 cm). The diameter of tillering in plants was higher (1.13 cm) on weeping lovegrass (P ? 0.001) compared with blue grama and side oats grama (0.82 and 0.76 cm). Forage production in with roller aerator, was lower (P <0.05) than in the range restored and harrow discs (207, 305 and 389 kg DM ha-1). Weeping lovegrass showed a better performance in emergence and survival, compared with blue grama and sideoats grama in PS, PH and TD. Seedbed prepared with a roller aerator, was lower in ability for DM ha-1 production, compared with seedbed prepared with range restored and disc harrow.
