At this present research, the aim was to assess the lettuce cultivars behavior above the organic farm system in climate and soil conditions at Seropédica-RJ. It was conducted two independent experiments, in the field, in two periods of the year, on randomized block design, with three repetitions and twelve plants per plot. In the first and second experiments were utilized as treatments 22 and 25 lettuce cultivars, respectively, belonging to the looseleaf and iceberg lettuce groups. In assessments of those experiments were considered fresh mass characters of the área part, head diameter, number of leaves, fresh mass of leaves and length of stem. When considering those five characters, for each group of lettuce, deduced that for the climate and soil conditions of Seropédica-RJ and management using the biofertilizer Agrobio® the cultivars Hortência, Regina de Verão, Stella, Tainá and Raider Plus had better performance.
