Zusammenfassung:ABSTRACT Industrial and organic residues cause environmental impacts at various levels. However, these residues present potential to correct soil acidity and fertility. Considering the possibility of using these alternative sources, the objective of this study was to analyze the quality of scarlet eggplant seeds produced with the use of industrial waste. The experiment was carried out in a greenhouse. We used scarlet eggplant seeds (Solanum gilo), cv. ‘Verde-Claro’, and the soil was Typic Hapludox. The experimental design was randomized blocks, in a factorial distribution (3x4x5), being three soil variations [(pure soil (S), soil + cattle manure (SE) and, soil + sewage sludge (SL)], four corrective treatments [without correction (C1), limestone (C2), steel slag (C3) and marble powder (C4)], and five periods of seed storage (0, 100, 120, 140 and 160 days). The use of steel slag and marble powder associated with the addition of sewage sludge and cattle manure increased fresh mass of plants, at 40%, and dry mass of plants, at 48%, when compared with the pure soil. After 140 day of storage, negatives effects on the vigor of scarlet eggplant seeds could be noticed. RESUMO Os resíduos industriais e orgânicos causam impactos ambientais em diversos níveis. No entanto, apresentam potencial para a correção da acidez e a fertilização do solo. A partir da possibilidade de utilização destas fontes alternativas, objetivou-se analisar a qualidade de sementes de jiló produzidas com o uso de resíduos industriais. O experimento foi desenvolvido em casa de vegetação sendo utilizadas sementes de jiló (Solanum gilo), cv. ‘Verde-Claro’. O solo utilizado é um Latossolo Vermelho-Amarelo distrófico. O delineamento experimental utilizado foi em blocos casualizados, com distribuição fatorial (3x4x5), sendo três variações de solo [solo puro (S), solo + esterco bovino (SE) e solo + lodo de esgoto (SL)], quatro tratamentos corretivos [sem correção (C1), calcário (C2), escória de siderurgia (C3) e pó de mármore (C4)], e cinco períodos de armazenamento das sementes (0, 100, 120, 140 e 160 dias). O uso de escória de siderúrgica e pó de mármore associados à adição de lodo de esgoto e esterco bovino aumentou as massas fresca das plantas, em 40%, e seca, em 48%, quando comparadas com o solo puro. Após 140 dias de armazenamento há efeitos negativos no vigor das sementes de jiló.
