摘要: Although researches on the environmental impacts of using waste as fertilizer is great importance, basic principle for a product that it should provide nutrients plants without causing any harm to them. The objective this study was evaluate agronomic traits (number nodes, plant height, leaf number, yield and protein content grains) nutritional status corn treated with sewage sludge. experiment conducted in municipality Jaboticabal Red Latosol. A randomized block design 4 treatments (0, 55, 110 167.5 Mg ha sludge) 5 repetitions used. At 30 d. a. e., dose presented higher values for: number stem diameter. 60 did not affect traits. No influence from tested observed grains yield. showed greater weight 100 seeds. All imbalances.
