The objective was to evaluate the leaf area index of six different grasses. The experiment was installed at the Instituto Federal de Tecnologia e Educação of Uberaba, using a randomized block design with split plots in time. The plots were sown: Brachiaria decumbens cv. Basilisk, Brachiaria brizantha cv. Marandu, Panicum maximum cv. Mombasa, Panicum maximum cv. Tanzania, Brachiaria brizantha cv. Xaraes, Cynodon dactylon hb. Tifton and the plots, ten seasons of evaluation in 10 x 6 factorial arrangement with four replications. Rates of leaf area of each forage at different times of year were evaluated. Compared to other forage species, Panicum maximum had a higher leaf area index when subjected to periodic fertilization and irrigation. Only in the late fall Brachiaria Xaraés IAF had increased, but did not differ significantly from the others. Key words: Leaf area, times, grass AbstractObjetivou-se avaliar o índice de área foliar de 6 diferentes gramíneas forrageiras. O experimento foi instalado no Instituto Federal de Educação Tecnológico de Uberaba utilizando delineamento em blocos ao acaso em parcelas subdivididas no tempo. Nas parcelas foram semeadas: Brachiaria decumbens cv. Basilisk, Brachiaria brizantha cv. Marandu, Panicum maximum cv. Mombaça, Panicum maximum cv. Tanzânia, Brachiaria brizantha cv. Xaraes, Cynodon dactylon hb. Tifton e nas subparcelas, dez épocas de avaliação em esquema fatorial 6 x 10 com quatro repetições. Foram avaliados os índices de área foliar de cada forrageira em diferentes épocas do ano. Comparadas com as outras espécies forrageiras, o Panicum maximum apresentou maior índice de área foliar quando submetido à adubação periódica e irrigação. Apenas no final do outono a braquiária xaraés apresentou IAF maior, mas, não diferenciou estatisticamente das demais.
