Production and quality of forage were evaluated in four dual-purpose wheat cultivars submitted to nitrogen fertilization and cutting regimes. The experimental design was randomized blocks with three replicates. The treatments consisted of four dual purpose wheat (BRS Figueira, BRS Umbu, BRS Guatambu, and BRS Tarumã), five nitrogen doses (0, 45, 90, 135, and 180kg ha-1 ), and three cutting managements (no cuts, one and two cuts). The studied variables were: forage production, leaf ratio, crude protein, in vitro digestibility of organic matter and total digestible nutrients. The nitrogen fertilizer showed a linear increase on the fodder yield and protein and there was no effect on other variables. Forage production increased in the second harvest and its quality decreased. The quantitative and qualitative results of the forage were different among cultivars. The longer cycle dual-purpose wheat had higher nutritional quality and lower forage production.
