The goal was to determine the ideal cutting age of elephant grass BRS Canará for forage production in the dry and rainy seasons. The experimental design comprised randomized blocks, with five treatments (42, 56, 70, 84, and 98 days in the dry season and 42, 60, 76, 91, and 105 days of regrowth in the rainy season) and four replications each. Agronomic, morphological, and chemical characteristics were evaluated. In the dry season, there was a significant quadratic response for plant height and leaf blade length. For the other characteristics, a significant linear response was observed, except stem diameter. In the rainy season, a quadratic response for the leaf blade length, leaf blade width, and leaf:stem ratio was observed. For the other characteristics, there was a significant linear effect, except for the percentage of dead material. In the dry season, a verified linear response was observed for the chemical characteristics, except neutral detergent insoluble protein. In the rainy season, a linear response was verified for all evaluated characteristics, except acid detergent insoluble protein. Elephant grass BRS Canará for forage production should be cut between 70 and 85 days in the dry season and between 60 and 70 days of regrowth in the rainy season.Downloads
