The study of the ratio yield-quality of “Fernão Pires” cultivar was based on a vineyard training systems (erected cordon) designe, established at “Dois Portos” in 1992. Only modalities of short pruning were selected for this study, established on a Calcaric Fluvisol (FLc). Those were an unilateral cordon with vines spaced 0,8 and 1 m in rows (5,000 and 4,000 vines/ha) and a bilateral cordon with vines spaced 1,2 m in rows ( 3,333 vines/ha). In spite of yields great difference in 1998, the results showed that the sugar content and the total acidity content of musts were not negatively affected by the grape production increasing. The specific characteristics of this cultivar, mainly it early maturation and its sugar high potential, could provide an explanation to these results.
