The experiment was carried out through october to december 2002, in the vegetable garden of the Departamento de Ciências Vegetais da Universidade Federal Rural do Semi-Árido, Mossoró-RN, Brazil. It was utilized a split-plot scheme with four replications in randomized complete blocks. To the plots were assigned the organic fertilizer doses (0, 60, 80 and 100 Mg/ha) and to the subplots the lettuce cultivars (Tainá and Elba). Evaluations were made on the basis of plant height and diameter, number of leaves per plant, shoot dry matter, and yield. The cultivar Tainá had greater fresh and dry matters weight and plant diameter, while the cultivar Elba had taller and leafier plants. Cropping there were significant differences. The best result for this crop was obtained with the 100 Mg/ha fertilizer level. The cultivar Tainá yielded better than Elba and increasing fertilizer level increased the values for the characteristics evaluated.
