Sunflower is an important oil crop that occupies an important place in the food supply of the state. It produces 90% of vegetable fats which are characterized by high nutritional value. In 2021, the sown area in Ukraine increased to 6.4 million hectares and our country has become a world leader in the production and export of sunflower oil, occupying a significant link in world production. It is projected that in the near future demand for these products will only grow, especially in Asia, America and the Middle East.
