The morphogenic characteristics of Brachiaria brizantha and Brachiaria decumbens were studied in function of different fertilization. The study was conducted in a green house evaluating two Brachiaria cultivars (B. brizantha cv. Marandu and B. decumbens cv. Basilisk) and five different fertilizations (no fertilizer, P, N, NP and NK). The assay was conducted in a 2 x 5 factorial scheme in a completely randomized design, with four repetitions. The morphogenic evaluations included leaf emergence, leaf elongation rates and filocron. The answer of the cultivars was quite expressive to the studied variables relative to nitrogen supply and its combination with phosphorus and potassium. The Basilisk grass was more productive than Marandu grass. The nitrogen importance as a tool to manipulate plant structure was evidenced.
