Effects of fertirrigation with compost tea of sewage sludge on growth and physiological quality in seedlings of Sesbania virgata (Cav.) Pers.

Resumo

In this study were evaluated effects of fertirrigation with different concentrations of compost tea of sewage sludge on cambaí-amarelo (Sesbania virgata) growing. Seedlings were grown in nurseries covered 50% shading and watered daily, composted sewage sludge was used in the concentrations 0 (Control), 0.15; 0.20; 0.25 and 0.30 mg.ml-1. The plant height, root growth, steam diameter and plant height/stem diameter ratio, shoot dry matter, roots dry matter and the total dry matter of the plants were determined 150 days after planting. Dickson quality index were calculated. In general, moderate concentrations of composted sewage sludge improves growth and biomass distribution. Composted solid waste showed promise for the production of Sesbania virgata seedlings.
