RESUMO
This study aimed to determine the energy productivity of the different compartments of above ground biomass of forest species Acacia mearnsii De Wild, Eucalyptus grandis W. Hill ex Maiden, Mimosa scabrella Benth and Ateleia glazioviana Baill distributed in different spacing in planting 2.0x1.0m, 2.0x1.5m, 3.0x1.0m and 3.0x1.5m, at ages of 1 and 3 years. The study was conducted in an experiment in the city of Frederico Westphalen-RS, in experimental design of randomized complete block with three replications. The determination of the energy productivity was carried out through the measurement of values of above ground biomass and power calorific value of each compartment. The different planting spacings induced different yields of biomass energy, and it was found a systematic negative trend in relation to the living space provided by lower planting space. The energy productivity achieved in the third year for all species, were higher than those of the first year. The species Eucalyptus grandis presented the greatest potential for energy productivity of wood and for the other species, equivalent to twice the Acacia mearnsii, the denser spacing (2.0x1.0m).
