Abstract: O presente estudo teve como objetivo analisar a variação sazonal dos preços médios recebidos pelos produtores de cana-de-açúcar no estado do Paraná, no período de janeiro de 2000 a dezembro de 2007. Para tanto, adotou-se a metodologia da média geométrica móvel centralizada de 12 meses. Os resultados mostraram que índices sazonais abaixo ou igual a 100 ocorrem em metade do ano e, de modo geral, coincidem com período de colheita e comercialização. Índices acima de 100 foram observados em períodos de plantio. Observou-se, também, que a maior amplitude entre os limites inferior e superior dos índices ocorre entre meses de índices mais baixos. Contudo, pode-se concluir, pelos resultados, que a cana apresenta uma sazonalidade de preços moderada.----------------------The present work aimed at analyzing the seasonal variation of the average prices received by the sugar cane producers in Paraná State, within the period from January 2000 through December 2007. For this work, the methodology of centralized mobile geometric average was applied. The results show that seasonal indexes either lower or equal to 100 happened in half of the year and, across the board, they coincide with the harvesting and commercialization period. Indexes higher than 100 were observed within planting period. Also, one observes that greater amplitude between the inferior and superior limits of the indexes occurs between months of lower indexes. However, one can conclude, by the results, that sugar cane presents moderate price seasonality.
