This study aimed to carry out the morphogenic, structural, and bromatological characterization of Brachiaria humidicola cv. BRS Tupi. A completely randomized design was adopted. The treatments consisted of harvesting the forage at 14, 28, 42, and 56 days. Leaf appearance rate, leaf elongation rate, and phyllochron were similar among the treatments (P > 0.05). However, leaf life span varied among treatments (P < 0.05). Dry matter exhibited linear behavior (P < 0.05) whereas mineral matter, crude protein, neutral detergent fiber, acid detergent fiber, and lignin had quadratic behavior. Brachiaria humidicola cv. BRS Tupi exhibits the best forage potential for animal feed between 28 and 42 days of growth.
