<p class="aresumo">This study was performed at the campus of the Semiarid Rural Federal University in Mossoró, State of Rio Grande do Norte, and aimed to evaluate the behavior of cotton (<em>Gossypium hirsutum</em> L. race latifolium Hatch), cultivar 8h as for growth and yield when fertirrigated with secondary domestic sewage. The experiment consisted of a randomized block split plot design, with dilutions of domestic effluents tested at plot level [25% - T₁, 50% - T₂, 75% - T₃, 100% of secondary domestic sewage - T₄ and 100% water supply with soil mineral fertilization – T₅] on soils of different textures. The plant height was significantly greater at only at 15 and 30 DAP, reaching a maximum value of 67.30 cm with 100% wastewater on the 50th DAP. The cotton production was not influenced by the application of different levels of secondary domestic sewage; but a linear increase of productivity was observed in the sandy soil, reaching 1,363.45 kg ha^-1 with the application of 100% of domestic sewage. On the Cambisol, the cotton plant presented the best results in terms of morphology.</p> <p class="akeyword"> </p>
