This experiment aimed to study the effects on grain and forage productivity in dual-purpose wheat cv. BRS Taruma under cutting handlings and nitrogen fertilization. The experiment was conducted in area of ​​Rhodic Hapludox in the city of Marechal Cândido Rondon, Parana State, in a randomized block design with 12 treatments and four replications. The treatments consisted of surface nitrogen levels (0, 60, 120 and 180 kg ha-1) and number of cuttings accomplished ​​(0, 1 and 2). The topdressing was split in two applications for handling of just a cutting (27 and 65 days after sowing - DAS), and three applications for handling with two cuttings (27, 65 and 96 days after sowing - DAS). Data were subjected to analysis of variance (p≤0.05). The use of one or two cuttings and the comparison between the first and second cuttings were done by F test (5%) whereas nitrogen doses were studied by regression analysis. For all variables, there was significant interaction of nitrogen doses in surface and the number of cuttings. Grain yield and its yield components were responsive to levels of nitrogen fertilization in surface as well as forage production and its quality, but the same factors were reduced with the use of cuttings. This handling increased the dry matter content and crude protein in grains.       Key words: Crop-livestock integration, Triticum aestivum, nitrogen, yield components, proximate composition.
