Conteúdo: |
The aim of this study was to evaluate the impact of pasture management practices on leaf canopy height (LCH) at 95% light interception (LI), since this is a valuable strategy of defoliation frequency. These relationships were investigated over two years with monocultures grown in a fully factorial block design crossing six C4 pasture grass species, two cutting intensities and two N levels. We found variations on LCH at 95% LI, mainly across seasons, but also between treatments. The range of these variations was species-dependent. Therefore, in order to maintain a target IL level, grassland managers should cut or graze at different heights according to the species and seasons. N fertilization and an increase in cutting height above ground level can provide a sward structure that allows lower pre-cutting/grazing height and, consequently, shorter intervals between defoliations. |
