This work had as objective to quantify the isolated and conjuntive effects of irrigation with treated wastewater and biosolids doses on growth of corn, after the cultivation of castor bean plant. An entirely randomized experiment in factorial scheme [(2 x 3) + 1] was accomplished, with treatments including two types of water (municipal supply water and treated wastewater), three biosolids doses (0, 75 and 150 kg ha-1) and a control with chemical fertilizer in the NPK formula, with three replications, resulting in 21 plots. It was verified that all the growth variables of corn were superior for the treatments that received wastewater. The biosolids presented significant effect only in height of plants, up to 20 days after sowing.
