Resumo: The work was carried out at Iapar in Paranavaí, state of Paraná, to evaluate the effect of nitrogen fertilization on access of BRA-006998, from 10/15/1998 to 05/03/1999. Four doses of N (0; 150; 300; and 450kg/ha/year) were applied to the pastures managed according to a rotational grazing. A randomized block design was used with split-plots, with N-doses studied in the plots and the GCs in the split-plots. The DM accumulation rate presented maximum value of 73.9; 96.2; 150.3; 189.6; and 129.9kg/ha/day (424; 438; 397; 385; 414kg N/ha/year, respectively) in the GCs 1, 2, 3, 4 and 5, respectively. The efficiency of N utilization in DM production did not differ between the treatments of 150 and 300kg N/ha/year, where the efficiency obtained with 150kg N/ha/year is higher than that obtained with 450kg N/ha/year.

A taxa de acúmulo de matéria seca máxima foi de 73,9kg; 96,2kg; 150,3kg; 189,6kg e 129,9kg/ha/dia (424kg, 438kg, 397kg, 385kg e 414kg de nitrogênio/ha/ano, respectivamente) nos ciclos de pastejo 1, 2, 3, 4 e 5, respectivamente. A eficiência de utilização do nitrogênio na produção de matéria seca não diferiu entre os tratamentos 150kg e 300kg de nitrogênio/ha/ano, sendo a eficiência obtida com 150kg de nitrogênio/ha/ano maior do que a obtida com 450kg de nitrogênio/ha.Editora da Universidade Estadual de Maringá2008-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.uem.br/ojs/index.php/ActaSciAnimSci/article/view/207210.4025/actascianimsci.v25i2.2072Acta Scientiarum.
