[Objective] This study aimed to improve the yield and quality of tobacco. [Method] Different proportion combinations of zinc sulfate and iron sulfate were applied to Jiyan 9, and its agronomic traits, field natural incidence, economic characters and chemical composition were compared among different treatments. [Result] Iron-zinc combined application improved the yield and quality of tobacco. Among all the treatments, Treatment 2 （FeSO4 15 kg/hm2 ＋ ZnSO4 10 kg/hm2） and Treatment 5 （FeSO4 15 kg/hm2 ＋ ZnSO4 15 kg/hm2） were the best. [Conclusion] This study will provide a theoretical basis for the improvement of yield and quality of tobacco.
