As the predominant form of agroforestry use in the world. Silvopasture is still insufficiently present on Slovenia under our conditions. After the establishment of vegetation suitable for this form of agricultural use, it is necessary to think about the improvment of the existing grass cover between and under the tree canopies. In 2018, we conducted an experiment Padež area on the Pokojišče plateau, to improve the grass cover by sowing selected species and mixtures of forage plants. On the partially tree-covered pasture, where controlled grazing and wintering of cattle has been taking place for many years, after sowing the selected species and mixtures, we carried out measurements, assessments andinventories of the grass cover in the trial and on the surrounding selected plots. In the first sampling (August 16), we obtained the highest yield in the plot with the grass mixture (0.35 t ss/ha) and the lowest in the plots with the orchard grass and meadow mixture without clover (0.2 t ss/ha). In the second sampling (October 17), yields were more uniform and smaller. The proportion of agricultural functional groups was more optimal within the experimental plots than in the surveys on the surrounding plots. However, diversity was greater in the experimental plots, which was also due to the greater number of plant species detected. The number of all species detected during the surveys was 137, of which 83 occurred in less than 20 % of the surveys. Improvement of swards in silvopasture is a demanding process, the success of which depends on many factors.
