To evaluate the utilization of the biofetilizer substituting nutrient solution in hydroponic lettuce was carried out the study in greenhouse at Environmental Science Departament of the UFERSA, located in Mossoró, Rio Grande do Norte State, Brazil. The statistical test was realized in randomized blocks, with thee repetitions. Treatments were composed of five nutrient solution (Biofertilizer - T1; Biofertilizer + 25% of the mineral nutrient solution - T2; Biofertilizer + 50% of the mineral nutrient solution - T3; Biofertilizer + 75% of the mineral nutrient solution - T4 and mineral nutrient solution - T5). The fresh and matter biomes, leaf area, diameter of caulis and number of leaf was analyzed. The T5 treatment showed better response in relation to growth parameters and production of hydroponic lettuce, demonstrating that in a hydroponic requires high levels of nutrients readily available to meet the rapid and high nutrient demand.
