Sažetak
Reduction of stocking rates and fertilizer inputs are recommended for maintaining or enhancing biodiversity of semi-natural habitats. White clover population could be affected by changes in grassland
production intensity. The aim of the present study was to investigate the white clover response on N application and stocking density. Three-year experiment was carried out on semi-natural grassland that was rotationally grazed with sheep. Three levels of N fertilizer were applied: 35, 100 and 150 kg N ha-1 (N35, N100 and N150, respectively) and two levels of stocking density were managed: 68 and 119 animal units ha-1 (ZP68 and ZP119, respectively) to investigate their effect on white clover dry matter (DM) yield, white clover content, frequency and regenerative ability. White clover DM yield and its content in the sward was not affected by the stocking density. The white clover content decreased during the experiment. The effect of N application on regenerative ability parameters was not constant and depends on the part of the vegetation season. These results indicate that the white clover is an unstable floristic component in the type of grassland investigated under applied management practice. However, reduction in N inputs is necessary to improve performance and the regenerative ability of the white clover.
