The experiment was conducted to evaluate the agronomic characteristics and chemical composition of different maize cultivars for ensiling of the plant. Twelve maize cultivar were analyzed in a completely randomized block design, with three block, twelve treatments and three replication. The plot with three lines of six meters long and spacing of 0.8 m were used in all trials. The cycle of the plants of the planting to harvest varied from 105 to 114 days. The height average differed among (P < 0.05) cultivars, and varied from 182.6 (AGN-3150) to 247.0 cm (AG-122). There was not difference among maize cultivars (P > 0.05) for ear by plant number (0.9 to 1.1), dry matter (33.2 to 38.2 %), ether extract (1.9 to 2.5 %) and neutral detergent fiber (49.1 to 56.2 %). The dry matter production differed (P < 0.05) among cultivar TORK (20.6 t/ha) and the cultivars CD-302 (16.4 t/ha) and TRAKTOR (15.7 t/ha). The AGN-3150 presented lower acid detergent fiber (24.2 %) and higher digestibility (80.7 %). All cultivars presented agronomic and qualitative characteristics for silage production, with TORK and AGN-3150 being the most outstanding.
