The study was designed as a factorial arrangement in randomized block design with four replications. After soil analysis of the study areas, K and Mg-fertilizers were applied at sowing. The results showed that the K applications alone could increase the nutrient concentrations of the leaves, and synergic relations were found between K and P, Fe, or Zn. Synergic relations were also found between Mg and P or Fe. Generally, combined applications of K and Mg resulted in higher nutrient concentrations in the leaves by ameliorating the antagonistic effect of poor soil K-Ca-Mg ionic balances. The leaf nutrient concentrations were generally higher in the first year (2009) than that of the experiment than in the second year (2010).eninfo:eu-repo/semantics/closedAccessMaizeLeafPotassiumMagnesiumNutrientsArticle224606616N/AWOS:000392936100015N/A
