Marandu, and the implications on the economic viability of production of Nellore heifers. This was a completely randomized design with four treatments (T1 = deferred pasture without nitrogen fertilization; T2 = deferred pasture fertilized with 50 kg N ha-1, T3 = deferred pasture with 100 kg N ha-1, T4 = deferred pasture with 150 kg N ha-1) and four replications (16 fertilized paddocks). First, there were used 48 Nellore heifers, average eight months of age and initial body weight of 178.69 ± 26.67 kg, with three heifers in each paddock, in all treatments, in a continuous grazing system, with variable stocking rate. Only the treatment the without nitrogen fertilization showed negative monetary values of R$ -181.96, R$ ha-1 -72.79 and R$ @-1 -32.11. The treatment with 50 kg N ha-1 achieved the highest positive monetary values of R$ 756.02, R$ ha-1 302.40 and R$ @-1 50.52. Economic viability data in beef heifer production demonstrate that the treatment with 50 kg N ha-1 is the most financially viable under the conditions of this study. 2016 artículo científico 1806-2636 https://www.redalyc.org/articulo.oa?id=303143565010 https://www.redalyc.org/journal/3031/303143565010/ https://www.redalyc.org/journal/3031/303143565010/html/ https://www.redalyc.org/journal/3031/303143565010/303143565010.epub https://www.redalyc.org/journal/3031/303143565010/movil en http://www.redalyc.org/revista.oa?id=3031 Acta Scientiarum.
