| Resumo: | Sewage sludge, a byproduct of wastewater treatment, accumulates a high content of organic matter, heavy metals and other toxic compounds. Due to its accelerated generation, adequate management is necessary for its stabilization and disposal. Vermicomposting is a management alternative that stabilizes residual sludge and allows its addition to the soil, improving structural properties and increasing its fertility. The objective of this study was to evaluate the effect of vermicompost of sewage sludge and equine manure on the productivity and antioxidant activity of basil plants (Ocimum basilicum L.). Vermicompost was developed in a 30:70 proportion of sewage sludge and equine manure, and the effect on basil was evaluated under different doses of vermicompost (20, 40 and 60 t/ha). The use of vermicompost significantly increased the growth rate, without causing effects on the antioxidant activity and the content of phenolic compounds in basil plants. |
