The use of organic residues in agriculture can contribute for the management of plant diseases and soil fertility. However, their effects are poorly understood for banana Fusarium wilt (FW), caused by Fusarium oxysporum f. sp. cubense (Foc). In this study was evaluated the biotic and abiotic effects on soil suppressiveness to banana FW after incorporation of composted sewage sludge, biochar, shrimp peel and mussel shell into the soil. Residues were incorporated (0, 1, 2, 3, 4, and 5%, v:v) in soil previously infested with Foc. Plantlets of banana cv. ?Silk? (AAB) were transplanted seven days after residues incorporation in 2 L pots. The assays were conducted in greenhouses located at the Embrapa Meio Ambiente, Jaguariúna, São Paulo, Brazil. A completely randomized experimental design with tenreplicates was adopted and was repeated twice. Sewage sludge at 4% and 5% reduced plant disease and increase plant growth, standing out from other residues and concentrations studied. In the intermediate group are all concentrations of biochar, as well as sewage sludge at 2% and 3%. The disease severity and plant growth were similar to the control in plants grown on soil containing shrimp peel and mussel shell. Negative correlations were found between disease parameters and soil basal respiration, bacterial population, electrical conductivity, pH, V%, CTC, P, K, Ca, Mg, Zn, Mn and B. |
