Abstract

The amount of energy produced (EP) is the energetic equivalent of the forage
biomass yield achieved from any type of association. Depending on the fertilization
level applied, in the case of the 10 associations studied, the energy amount achieved
in a 3-year period was 9181 KWh/ha, respectively 2.7 times bigger than the energy
input (EI). The graminaceous and legume associations studied recorded a relatively
low average capitalization coefficient of the energy input (0.37), proving the
technological efficiency of these crops.
