Therefore, this research has the objective to verify the performance of dual purpose wheat with different cutting regimes and seeding density. The whet cultivate used were: 'BRS Figueira', 'BRS Guatambu', 'BRS Tarumã' and 'BRS Umbu'. The seeding density was of 50, 200, 350, 500 and 650 seeds for square meter. The phitomorfological and production variables have a different performance depending on as cultivar, management and seeding density. The cultivar 'Figueira' has the highest productive potential yield within the range of densities analyzed for dry mater production in relation to other cultivars The grain yield had significant interaction between cultivars and management (with and without cutting). The cultivars with higher grain yields were, respectively, 'Figueira', 'Umbu', 'Tarumã' and 'Guatambu' in managing blunt, already in the court system the cultivar 'Tarumã' was the one that had the highest grain yield, differing from the others. The most high and significant correlations occurred in plots with and without cutting. The court dropped all values of yield components, and grain yield of all cultivars.
