This study evaluated the parameters of the growth of corn plants (Zea mays L.) grown in pots containing soil plus tannery sludge vermicompost and irrigated with household wastewater. The arrangement of treatments consisted of a factorial 2x6 (two types of irrigation and six fertilization treatments) in a completely randomized design (CRD) with five repetitions. The height of the plants and the diameter of the stems were evaluated bi-weekly. The results indicated that both the wastewater and the tannery sludge vermicompost are good sources of nutrients for the plants, promoting their growth. We conclude, therefore, that wastewater from households and tannery sludge vermicompost can be considered an agricultural waste of interest for the corn crop.
