The primary goal of agricultural production is to produce adequate quantity and quality of crops. One crucial aspect of this is providing the appropriate nutrients to plants. In recent times, there has been a growing emphasis on replenishing micronutrients beside macronutrients, as essential microelements, although in smaller quantities, are indispensable for the cultivation of our crops. In our three-year small-plot experiments, the effect of two foliar fertilizers, Vinasse, which is a byproduct of alcohol production, and a zinc complex on the yield, crude protein, and gluten content of winter wheat, was investigated. The effects of these formulations when applied as foliar fertilizers separately and together, at doses of 50, 100, 250 and 500 l/ha for Vinasse and 0.5 kg/ha for zinc complex, were examined. Based on the results of the small-plot experiments set up in the fall of 2020 and 2021 and harvested in the summer of 2021 and 2022, it can be concluded that using Vinasse + zinc complex treatments a higher yield and better content indicators were achieved compared to the control plots. The highest dose of Vinasse (500 l/ha) + zinc complex (0.5 kg/ha) had the greatest positive effect on yield values.
