Abstract

The frequency of the appearence of atypical dry
and rainy periods in the last years, has put up with the
establishment of a new conception for the evaluation and
management of sugarcane varieties, with a view to framing
correctly the harvesting stage and its possible lengthening in
certain places. Under those new premises 48 experiments in
blocks totally at random were designed and established in
four contrasting regions of the country. The behavior of three
representative varieties of sugarcane of three different maturity
periods (early, middle and late), harvested during the whole
year, with ages between nine and 24 months, in the variable
tons cane/ha, percentage of pol in cane and tons pol.ha-1 was
studied. It was obtained as a result that the counties of
Camagüey and Matanzas reached the highest values in the
pol percentage in cane to harvest beginnings (November-
December) in the three evaluated cultivares, while Holguín
achieves them in the period from April-July. In accordance
with the obtained results is possible to harvest with a bigger
sugar content, if the crop age is increased and this is made in
early time for traditional harvests (November-January) and
varieties corresponding to the «families» of early and
intermediate maturation are used, suggesting the possibility
to contain crop ages and to determine the best combinations
«family-age-moment» for edafoclimatic region, in such way
that can guide the composition varietal and of stumps to be
able to take place with the biggest efficiency.
