Resumo: | The objective of this work was to evaluate the effect of nitrogen and phosphorus fertilization on the regrowth, tiller density, tiller weight, dry matter yield (DMY) and green leaf blade dry matter (LBDM), under levels of nitrogen (0; 200; 400; 600kg/ha of N) and phosphorus (0; 50; 100; 150; 200Kg/ha of P2O5) of Marandu grass (Brachiaria brizantha (Hochst) Stapf cv. Marandu), during the summer (SP) and winter periods (WP). The experimental design was randomized blocks using factorial design 4 x 5, with three replications. Nitrogen fertilization produced (p < 0.05) a linear increase in the SP and a quadratic response in the WP. The DMY and leaves dry matter yield (LBDM) had a quadratic response and a linear increase in the WP, by crescent levels of nitrogen fertilization (p < 0.05). However, tiller density showed a linear decrease, by phosphorus (p < 0.05) at RP, and a quadratic response at WP. The weight of tiller and root was not statistically different (p > 0.05) by crescent levels of nitrogen and phosphorus fertilization in both periods. Results showed that nitrogen fertilization in pasture of Marandu grass increase DMY and LBDM, during the SP, and phosphorus fertilization did not affect the analyzed variables. |

Marandu), no período de verão (PV) e inverno (PI). Utilizou-se um delineamento experimental de blocos casualizados, fatorial 4 x 5 com três repetições. O VR apresentou comportamento linear no PV, e quadrático no PI, em função do nitrogênio (p < 0,05). A produção de MSVT e de MSVLF aumentaram de forma quadrática no PV e linear no PI, respectivamente, à medida que aumentou os níveis de nitrogênio ( < 0,05). Entretanto, a densidade de perfílhos decresceu linearmente em função do fósforo no PV, e quadrático no PI. O peso de perfílhos não alterou (p > 0,05) em função do nitrogênio e do fósforo, em ambos períodos. A utilização do adubo nitrogenado melhorou a produção MSVT de (MSVLF), durante o PV, porém, a aplicação do fósforo não afetou as variáveis avaliadas.Editora da Universidade Estadual de Maringá2008-04-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.uem.br/ojs/index.php/ActaSciAnimSci/article/view/183610.4025/actascianimsci.v26i3.1836Acta Scientiarum.
