The aim of this study is to analyze the historical evolution of prices paid to the horticultural farmers in Rio Grande do Sul, between 1973 and 2006, paying especial attention to the period before and after the monetary stabilization achieved through the Plano Real, in 1994. The historical series of nominal monthly prices of the analyzed horticultural products (cassava, potatoes, onions, tomatoes, oranges, satsumas, apples, peaches and grapes) were obtained from EMATER-RS. Through this study it was possible to conclude that all of the products analyzed had a significant decline in their prices from 1973 to 2006. It was verified that the eighties represent the period with the highest price drops for horticulture, and the period after the implementation of the Plano Real had the strongest price reductions for fruits.
