The role of some elements of mineral nutrition in the formation of the productivity of sunflower as a valuable oil crop. Актуальні напрями та проблематика у технологіях вирощування продукції рослинництва: матеріали V міжнародної науково-практичної інтернет-конференції (м. Полтава, 25 листопада 2025 р.). Полтава: ПДАУ, 2025. С. 9-12. ISBN: 978-617-8466-56-5This article evaluates the physiological significance of specific mineral nutrients in the growth, development, and yield formation of sunflower (Helianthus annuus L.). The author examines how the balanced application of primary macronutrients (nitrogen, phosphorus, and potassium) interacts with essential meso- and micronutrients, specifically sulfur, boron, and magnesium, to maximize the genetic potential of modern hybrids. The research highlights the critical role of boron in pollen viability and seed setting, as well as the impact of sulfur on oil biosynthesis and nitrogen assimilation. The study analyzes the correlation between nutrient availability during the generative phases and key productivity indicators, such as head diameter, thousand-seed weight, and oil content. The findings substantiate that a targeted, phase-specific fertilization strategy is crucial for increasing the resource efficiency of sunflower production and ensuring its status as a highly profitable oilseed crop in various agro-climatic zones.enSunflowermineral nutritionproductivityoil contentboronsulfurfertilization strategymacronutrientsyield componentsArticle
