摘要：

Research objective was to examine the effect of nitrogen (N) application (0-N-0 and 150 kg ha(-1) year(-1)-N-150) and rotational grazing by cattle (C) and sheep (S) on the dry matter (DM) yield and persistence of white clover in mixtures with grasses. N-150 Significantly reduced the growing points, stolon length and stolon dry weight by more than 70% compared to N-0. Grazing treatment affected stolon population density only in interaction with N. The highest stolon population densities were achieved with SN0. S had higher clover DM yield than C. N-0 had higher clover DM yield than N-150. However, the interaction grazing management x N rate was significant, so the highest yield of white clover was recorded for SN0.
