Compared to temperate systems, there have been few detailed assessments of canopy characteristics and associated grazing behavior in planted tropical grasslands. Reasons include the large number of forage species used in warm climates, the diversity of their morphology, research priorities emphasizing germplasm evaluation and management, and limited resources. This review describes canopy attri...
Plant species diversity may benefit natural grassland productivity, but its effect in managed grassland systems is not well understood. A four-year multispecies grassland experiment was conducted to investigate the effect of species diversity-legumes and non-leguminous forbs-on productivity, persistence and sward quality under cutting or grazing regimes and with or without slurry application. T...
The climate warming and changes in weather patterns Europe are negatively affecting the structure of grassland swards. disappearance valuable forage grasses can be observed. Therefore, order to keep productivity high, high-yielding good quality that resistant being sought. At moment there few publications which present long-term influence changing conditions on meadow sward its fodder value. Th...
(1) Ramets of Trifolium repens were sampled from sites in a field of permanent pasture dominated by a mosaic of Lolium perenne, Holcus lanatus, Cynosurus cristatus and Agrostis tenuis. After multiplication of the ramets in a glasshouse, they were transplanted back into the original swards in all combinations of clover 'type' and site of origin. The pre-existing vegetation on the sites was eithe...
Extensive management is one of the methods used in conservation fen meadows. The aim study was to characterize grassland communities grazed by Konik horses Biebrza National Park and assess influence short-term grazing on sward. During a 3-year period, phytosociological studies, measurements sward cover height, as well an assessment botanical composition meadows were conducted places excluded fr...
Perennial ryegrass is one of the most commonly cultivated forage species in Europe, where grazing and mowing (cutting) are used to manage this resource. Cutting can be characterized by its intensity (height) and its frequency. Combinations of these two factors affect mono-species grasslands productivity and could also modify the genotypic composition of heterogeneous populations. Indeed, the hi...
