The objectives of this study are to determine the effects of prescribed burning on the productivity and quality of six tropical grass species under semitropical conditions on the Pacific Coast of Mexico. Tame tropical pastures in this area are used for beef cattle production, but due to past growing conditions and maturation of the plants, nutritive value and intake are affected, thus limiting animal performance. Considering this, fire can be a useful tool for better management and production of these types of pastures.
