The experiments were set as factorial experiment design in randomized blocks and 4 replicates. Potassium and Mg-fertilizers were used in the single time into base in the sowing. According to the results, K application in the increasing doses increased yield components more than that of Mg. Together giving of the K and Mg in certain combinations took the yield components to maximum levels. The highest grain yields were obtained by the K40Mg40 in the first year (7313kg ha(-1)) and by the Mg-60 in the second year (6510kg ha(-1)).en10.1080/01904167.2016.1187741info:eu-repo/semantics/closedAccessKonya Province of Turkeypotassiummagnesiumsunfloweryield componentsArticle391217341744Q2WOS:000386032600008Q4
