Sažetak
The objective of this experiment was to measure the effect of four grazing dates in spring differing by one week on grass/clover ratio in a pasture within 3 years. A grazing experiment with Charolais yearling steers (Bos Taurus L. ; average 360 kg) was conducted on an experimental pasture in the region of Medvednica mountain, at an altitude of 680 m, from May to October. These grasslands are anthropogenic communities and belong to the following associations: Arrhenatheretum medioeuropaeum (Br-Bl-19) Oberd. and Lolio-Cynosuretum (Tx 37). They show the tendency of vegetation growth towards the climatic i.e. forest community. The pasture predominant grasses were orchardgrass (Dactylis glomerata L.), perennial ryegrass (Lolium perenne L.) and red fescue (Festuca rubra L.), while the major legume was white clover (Trifolium repens L.). The experiment was designed as a randomised block of four treatments (grazing dates). It could be concluded that grazing dates had an important influence on grass/clover ratio in a particular pasture during 3 years period, showing tendency of increasing percentage of both grass and clover in 2 earlier grazing dates, compared to delayed 2 grazing dates.
