The effect of harvest term and grass species on qualitative parameters of biomass used for direct combustion

Original language description

The dynamics of DM content, energy and nitrogen content in biomass of B.inermis, B. marginatus, F. arundinacea and Festulolium Felina was studied in the years 2003-2004 to determine an optimal term of harvest of grass species grown for the production ofbiomass for direct combustion. The experiment was established at the Czech University of Agriculture in Prague (latitude: 50°08´ N, altitude: 14°24´ E) in 2002. The selected characteristics were studied during vegetation in one month intervals from the mid-May. DM content was highest in B. inermis and B. marginatus in the last two terms of sampling. The highest gross calorific value was in B. inermis and B. marginatus biomass 18,26 kJ/g and 18,17 kJ/g respectively. Net calorific value was strongly influenced by sampling term and ranged from 2,61 kJ/g in the first sampling to 9,78 kJ/g in the fifth sampling term. The nitrogen content was significantly higher in the first sampling compared to the others (P < 0,0001).
