The purpose of this study is to assess the energetic potential of biomass derived from differentparts of maize: stalks, cobs and grains. The researches were performed in the Laboratory of Solid Biofuels withinState Agrarian University of Moldova, using standard methods of estimating the physical and mechanicalproperties of lignocellulosic biomass. Samples were taken at random from several areas of the Republic ofMoldova. It was found that moisture content, ash content and calorific value varied significantly depending onthe structural part of the tested maize. Calorific value is quite high in grains (GCV = 18,5 kJ/kg; NCV = 17,3 MJ/kg)and in stalks (GCV = 18 kJ/kg; NCV = 16,7 MJ/kg). The corncobs (without grains) have lower calorific value (GCV= 14,82 kJ/kg; NCV = 13,62 MJ/kg). The ash content, anhydrous state, resulting from the burning of differentparts of maize, has very low values ranging from 1.25 to 4.61%
