The objective of this study was to assess performance of wheat seeds after application of three components [fungicide, zinc (Zn), and polymer], separately or with their combinations, as well as assessing seed quality and yield. Thus, the treatments consisted in combinations of fungicide + zinc (Zn) + polymer, totaling six treatments, with four replicates per treatment, as follow: T0 - without application of Zn, fungicide, or polymer (control); T1 - Zn; T2 - Zn + polymer; T3 - polymer; T4 - fungicide; T5 - polymer + fungicide; and T6 - Zn + polymer + fungicide. The performance of the seeds originating from plants whose seeds had been pre-treated was assessed by tests of germination and vigor, in addition to analyzes of growth and yield. It was concluded that wheat seeds treated with zinc, fungicide and polymer are positively influenced until 30 days after emergence. The germination of wheat seeds is positively influenced by the treatment with fungicide, as much when separately applied as in combined application with zinc and polymer. The yield per plant increases when seeds are treated with Zn.
