Resumo: The present study evaluated the residual effect of sewer sludge produced in the ‘Estação de Tratamento de Esgoto’ (ETE), in Goiânia, Goiás State, Brazil, treated with 50% (v/v) of CaO and a bio-stimulator on the Stylosanthes guianensis cv. Mineirão fitomass yield, at two harvest dates. The first cut occurred 150 days after sowing, and the second, 273 days after the first harvest (423 days old). Eight treatments were evaluated: control; mineral fertilization; 20 Mg ha-1 biosolid; 20 Mg ha-1 biosolid + bio-stimulator; 40 Mg ha-1 biosolid; 40 Mg ha-1 biosolid + bio-stimulator; 60 Mg ha-1 biosolid; 60 Mg ha-1 biosolid + bio-stimulator. The experimental design was randomized complete blocks, with four replications. In the first harvest, the yield did not show significant differences between the mineral fertilization treatments and the treatments with increasing biosolid doses without bio-stimulator. All treatments with bio-stimulator showed negative effects on S. guianensis yield. In the second harvest, it was noticed a tendency to increasing yields for all treatments, except for the treatment that received chemical fertilization. The yield obtained in the treatments that received bio-stimulator were similar to the control and significantly lower than for other treatments. The results suggest the existence of a biosolid residual effect. KEY-WORDS: Sewer sludge; biosolid; degraded areas; bio-stimulator.

O presente trabalho teve como objetivo avaliar o efeito residual do lodo de esgoto produzido na Estação de Tratamento de Esgoto (ETE) de Goiânia, GO, tratado com 50% de cal virgem (v/v) e um bio-estimulador sobre a produtividade de fitomassa de Stylosanthes guianensis cv. Mineirão, em duas épocas. A primeira foi aos 150 dias após o plantio e a segunda aos 273 dias após a primeira colheita (423 dias de idade). Foram aplicados oito tratamentos: testemunha; adubação mineral; 20 Mg ha-1 de biossólido; 20 Mg ha-1 de biossólido + bio-estimulador; 40 Mg ha-1 de biossólido; 40 Mg ha-1 de biossólido + bio-estimulador; 60 Mg ha-1 de biossólido; 60 Mg ha-1 de biossólido + bio-estimulador. O delineamento experimental adotado foi o de blocos completos casualizados, com quatro repetições. No primeiro corte, as produtividades não diferiram significativamente entre os tratamentos com adubação mineral e os tratamentos com dosagens crescentes de biossólido na ausência do bio-estimulador. Verificou-se que o uso do bio-estimulador afetou negativamente a produtividade de S. guianensis. No segundo corte, observou-se tendência de aumento da produtividade em todos os tratamentos, com exceção do que recebeu adubação química. As produtividades obtidas nos tratamentos que receberam bio-estimulador foram semelhantes à testemunha e significativamente inferiores aos demais tratamentos. Os resultados indicam a existência de efeito residual do biossólido.
