Abstract

Sweet sorghum has great bioenergetic potential and has interesting characteristics in terms of rusticity,
adaptability and productivity, but more conclusive studies regarding the recommendation of cultivars,
productivity and ideal cutting time are needed to minimize risks and enhance results. Thus, the objective of
this work was to evaluate three genotypes of sweet sorghum and identify the best harvest time to obtain
a higher ethanol yield under the soil and climate conditions of the central region of the state of Tocantins.
The experimental design used was in randomized blocks in subdivided plots, with the genotypes of sweet
sorghum in the plots (cultivar BRS511 and lines 201813B 01 and 201814B 01) and in the subplots the four
cutting times, at 75, 90, 105 and 120 days after sowing (DAS), with four replications. The agronomic and
industrial characteristics of sweet sorghum for ethanol production were evaluated and it was concluded
that the genotype and the harvest time interfere directly in the production of ethanol. Among the materials
studied, the BRS 511 stood out, which showed the highest ethanol production, maintaining the high up to
120DAS.
