ABSTRACT
This study, carried out in a sugarcane mill located in the center-west
region of São Paulo state, Brazil, aimed to evaluate the association of sucrose
amount (POL%) with sugarcane varieties and cutting stages using mechanized
harvesting. A two-way analysis of variance (ANOVA), complemented by
multiple comparison tests, was used in order to identify the effects of variety
types and cutting stages on the sugarcane POL% content. An interaction between
the sugarcane variety and the cutting stage was observed; therefore, both two factors cannot
be independently evaluated regarding POL%. In addition, it was found that the
sucrose amount from the plant production in the evaluated period presented
significant differences between the cutting stages only for one variety, namely
CTC2, which was different from the others in most of the cutting stages.
Considering the observed results, it can be concluded that analyzing sucrose
amount statistically in the mill production can allow producers to posteriorly
better monitor information on the sugarcane varieties harvested under
mechanized processes.
