DELGADO MORA, Irenaldo et al. Influence of age and variety of sugar cane cultivation in the harvest time. Ctro. Agr. [online]. 2016, vol.43, n.2, pp. 59-65. ISSN 0253-5785.

One element that affects the quality of the cane is the gap, when the harvested cane has not reached maturity or have exceeded the time of optimum maturity, affecting the juice composition in terms of quality. So the objective was to determine the influence of age and cultivar in sugarcane. In plant and first ratoon crops with aged 9-24 months, were evaluated with the aim of determining the influence of the gap in the sugar content the discriminate analysis for plant and first ratoon cane at the beginning of harvest revealed that harvest with less than 12 months and above 19 months age can result with lower sugar yields due to lag, the C1051-73 and C86-12 genotypes achieved the highest percentage of pol in cane harvested in early ages of 18 to 20 months and in the final stage of harvest was between 13 and 16 months. The gap by genotype confirmed that My5514 is not recommended for the initial stage of harvest.
