【 摘 要 】

This experiment was carried out in the Arenito soil of the Cidade Gaúcha county, Northwest Paraná in Brazil, in which 0, 150, 300, 450 and 600 m³ ha-1 of wastewater were applied onto soil and the crop yield and soil chemistry were investigated for lopsided oat (Avena strigosa Schreb.) plants. The crop yield from the control was 2818 kg ha-1 contrasting 3629 kg ha-1 when 300 m³ ha-1 of cassava wastewater were applied, and potassium, after haversting, was the only nutrient found in a higher concentration in the soil profile.
