The work deals with the analysis of production and economic parameters of plantation short rotation coppice LMB in LS Deblín. Production plantation was assessed after 7 and 8 years since its inception through a network of inventory plots and stencil poplar. Surveys to be wood volume (m3) and the total biomass (o.d.t). Plantation economy was measured as the difference between revenues and costs. The survey was also regenerative experiment to assess the influence of the width of the cuts on the growth of poplar saplings. Total volume production of tree plantations for 2012 was set at 46,95 +/-9,7 m3. Total volume production of tree plantations for 2013 was set at 63,41 m3 +/-10,5 m3. Total dry weight biomass for 2012 amounted to 23,31 t/ha ie 3,33 t/ha/year. The following year, the total biomass dry weight was for 8,42 t/ha greater. The average production was also greater, it reached 3,97 o.d.t/ha/year. The total cost of the plantation in the first rotation reached 79 022 CZK. The cost of timber harvesting in 2012 amounted to 7 485 CZK. The total yield of the plantation in 2012 was 72 906 CZK. The profit in 2012 amounted to -6 116 CZK . Total revenue for 2013 amounted to 99 249 CZK. The profit in 2013 amounted to 20 227 CZK. Next experiment shows vigorous sprouting capacity. Wider cuts (3 lines) is generally larger than the cuts closer (2 lines). It was also found that the wider lines is greater proportion of sprouts in the greatest height class (+2 m).
