Description
Grazing pressure must be related to the pasture potential capacity of recovery. The measurement of leaf area index (LAI) is a way of evaluating that effect. Whatever the management, the main objective will be to allow pasture to reach a high LAI status and its' maintenance (Peterson, 1970). In elephant grass the stem/leaf ratio was used to indicate the dry matter production and indirectly indicates the grazing pressure (Rodrigues, 1984). Present experiment was done to evaluate the evolution of leaf area index (LAI), leaf/stem ratio (L/S), percentages of crude protein (CP), crude fiber (CF) and in vitro dry matter digestibility (IVDMD) and dry matter production (DMP) through the increasing age of the plants.
