This increases the input cost considerably. However, such problems can be eliminated thanks to the inputs obtained from completely natural plant wastes. Ash obtained from sunflower plant wastes, especially those used as fuel, has the potential to be an important natural fertilizer with plant nutrient elements in its content. In this study, it was aimed to determine some plant nutrients (B, Mg, P, K) found in the ashes obtained from burning of different variety (Coral, Pioneer63F73, PioneerP64LL05, Pioneer64LC108, Goldsun, Şems, Aga1301, Duna, Bosfora ve PioneerPR64G46) of sunflower plant wastes. As a result of the study, the highest B and Mg content was obtained from Pioneer PR64G46, P and Ca content from Pioneer P64LL05 and K content from Pioneer 64LC108. Observations show that the ash of the sunflower wastes has a very high content of phosphorus and potassium, and that these ashes can be used as fertilizers, especially in phosphorous and potassium-poor soils.eninfo:eu-repo/semantics/openAccessHelianthus annuus LfertilizersvarietypotassiumphosphorusArticle16221722110.25308/aduziraat.5898151142719
