Abstract

Through this price behavior of rice, bean, corn and fat steer, received by rural producers of the Goiás State, was studied, making comparison of seasonal variation respective patterns, during 1974/79 and 1979/84 periods. The method used to determine the seasonal pattern was the centralized geometric moving average. As auxiliary resources for indication of patterns variation, the ordinal correlation coefficient of Spearman was used, test equality of two variances and comparison of seasonal index amplitude applied to both periods. It was observed a change in the pattern of seasonal variation for all products having increased chiefly the amplitude of seasonal index in 1979/84 period in relation to 1974/79. The principal responsible for alteration may have been governmental interference in those markets.
