The plant biomass (wood, straw, energy crops) is one of the most important renewable energy sources in Lithuania and Europe. As renewable energy sources can be grown in short rotation e-nergy crops - willows and black poplars. When geometric indicators, it can be said that the willows thicker the more the fruits dry weight equal to 895,67±11,5 kg m-3. Similar results is of black pop-lar - 879,05 ± 20,93 kg m-3. Cutting the stems with screw cutter found that the largest chopped fraction accumulates on the screen when the screen hole diameter of 8 and 16 years old. The lar-gest fraction of the set when the willow stems are thicker Gl.1 - GL.2 75.77 % and 62.18 %. The evaluation of poplar, the largest fractional composition determined when the stems are thinner at the screen hole diameter of 8 mm fraction is equal to 66.72 % and 71.76 %.
