The objective was to evaluate the effects of levels of compost and fertilization with NPK on growth and production of lettuce. The experiment was carried out in a greenhouse, in a completely randomized design in a 6 x 2 factorial scheme, with four replications, considering six levels of compost (0; 25; 50; 75; 100 and 125 g plant-1) and absence and presence fertilization with NPK. The evaluated parameters were number of total and commercial leaves, mass of fresh commercial and total aerial part, mass of commercial and total dry aerial part, dry root mass and total dry mass. There was an interaction between the drilocomposite and NPK fertilization for the evaluated parameters, except for root dry matter. The fertilization with NPK increased the growth and production of lettuce when there was no application of the compost. Likewise, that the levels of this fertilizer increased the growth and production of lettuce only in the absence of NPK. The application of drilocomposite increases the growth of lettuce plants and can replace fertilization with NPK.
