ABSTRACT In order to provide scientific information about the irrigated cauliflower production in Northeast of Para, an experiment was installed in the Federal Rural University of Amazonia farm with the Desert hybrid under different water tensions on the ground and boron doses in the municipality of Igarapé-Açu – PA. The experimental design was a randomized block in a 4 x 4 factorial, sixteen treatments with three replications. The treatments consisted of four water tensions on the ground (15, 30, 45 and 60 kPa) as an indicative of the time to irrigate and four boron doses (0, 2, 4 and 6 kg ha-1). The irrigation was performed with drippers and irrigation management with tensiometers. Each plot, 4 m2, consisted of 8 plants located in the spacing of 1.0 m between lines and 0.5 m between plants. The hybrid is promising for cultivation in the soil and climatic conditions of the region where it was evaluated, with productivity of 17.1 t ha-1, fresh mass of the inflorescence of 0.85 kg plant-1, inflorescence diameter of 18 cm, in 38 kPa tension. The optimal dose of boron which ensured greater production of dry mass was 3 kg ha-1.
