Consideration should be given to the use of industrial waste as sources of fertilizers to soil andplants. The objective of this work was to study nitrogen rate as a function of filter cake doses inthe initial development of pre-sprouted sugarcane seedlings. The was design completelyrandomized in a 4x3 factorial scheme, with 4 doses of filter cake and 3 doses of N, with 4replicates. The variety used was CTC 9003. The evaluations occurred with 76 DAT (days aftertransplantation): number of tillers, height of plants, mass humid of the part aerial, total dry massand root/shoot relationship. The use of filter cake at doses of up to 60 ton ha-1combined with 100kg ha-1of N improves the initial development of sugarcane, being a viable alternative for thedestination of this residue in the soil.
