In this study, 3 doses of potassium (K) (0, 10, and 20 kg da(-1)) of K2SO4 (50% K2O) fertilizer and 3 doses of humic acid (HA) (0, 20, and 40 kg da(-1)) (85% HA) were used. Increase in the HA dose reflected significant effects on pH, salt, organic matter, phosphorus, magnesium, iron, and manganese contents of the experiment area at p < .01 level. It was determined that increased potassium applications affected the salt, magnesium (Mg), iron (Fe), and copper (Cu) contents at p < .01 level. Increased HA application on plant growth criteria had a significant effect on biological yield, grain yield, and harvest index (p < .01). However, K did not reflect any effect on the growth stage of wheat. Increased number of HA applications on grain and straw nutrient content were found to have significant (p < .01) effects on P, K, Ca, Mg, Fe, and Zn. Increased potassium applications had an effect on the P, K, Mg, Fe, and Zn contents with a significant level (p < .01). It was observed that HA applications were more effective than potassium applications on both general soil properties and yield and nutrient content.eninfo:eu-repo/semantics/closedAccessHumic AcidsNutrientsPotassiumWheatYieldArticle10.1080/01904167.2019.16587774220275727722-s2.0-85073834369Q2WOS:000486650200001Q3
