Abstract

The experiment was conducted, during two years at UNESP, Jaboticabal, to evaluate the cool season grass introduction on the Tifton 85 pasture to reduce the forage deficit during the winter/spring season. It was evaluated the following winter species: bristle oat; yellow oat; triticale, and yours mixtures. During the experiment it was determined the herbage mass (HMP) before grazing, agronomic characteristics botanical composition, changes on the herbage mass of each pasture component, leaf/stem + sheath relation. On the first year, at the first and second growth period (GP), it was observed highest herbage mass on the every overseeded pasture, except on the triticale, and bristle oat + triticale areas. This pastures showed changes in the herbage mass compared to the Tifton 85 (control) on the first GP. Every pasture decreased the leaf/stem + sheath ratio during the first to second GP. In the second year, the herbage mass was lowest in the fifth evaluation, compared to the first year. In relation to the GP, the highest herbage mass occurred on the third and fourth spring growth period. The cool season grass occurrence was highest on the first GP, and decreased during the spring evaluations.
