This research aimed to evaluate the effect of cassava wastewater fertilization on maize growth. The experiment was carried out under greenhouse conditions at the Federal Rural University of Pernambuco (Brazil). Treatments were assigned in a factorial arrangement 5 x 3, being 5 cassava wastewater doses: 0, 12.6, 25.2, 50.4 and 75.6 [m.sup.3] [ha.sup.-1] and 3 harvest ages: 20, 40, and 52 days after germination (DAG), in a completely randomized design, with four replications. A hybrid of forage maize (AG 1051) was used, keeping one plant in a 20 L pot. The variables evaluated were: plant height, stalk diameter, number of leaves, dry and fresh matter of leaves and stalks. The dose equivalent to 63 [m.sup.3] [ha.sup.-1] provided the highest gain in stalk diameter, number of leaves, dry and fresh matter of leaves; while the dose equivalent to 75.63 [m.sup.3] [ha.sup.-1] provided significant increase in the other evaluated phenological parameters. Cassava wastewater presented as a useful fertilization source for maize crop, however responses depended on utilization of appropriated cassava wastewater doses.
