The role of elements of mineral nutrition in the processes of corn productivity formation. Актуальні напрями та проблематика у технологіях вирощування продукції рослинництва: матеріали III міжнародної науково-практичної інтернет-конференції (м. Полтава, 7 травня 2025 р.). Полтава: ПДАУ, 2025. С. 7-9.The article provides a comprehensive analysis of the physiological and agrotechnical roles of essential mineral nutrients in the formation of corn (Zea mays) productivity. The author examines the specific functions of nitrogen, phosphorus, and potassium as the primary drivers of biomass accumulation and grain development. The research focuses on the "critical periods" of nutrient uptake, particularly from the 3–5 leaf stage to flowering, where the availability of macro- and microelements (such as zinc and boron) directly determines the potential number of kernels per ear. The study evaluates how balanced fertilization programs influence photosynthesis efficiency, root system architecture, and the plant's ability to withstand environmental stressors. The findings substantiate that the precise synchronization of nutrient supply with the crop's biological requirements is a fundamental factor in maximizing yield potential and improving the quality indicators of corn grain.enCornmineral nutritionproductivitynitrogenphosphoruspotassiummicronutrientsphotosynthesisyield formationnutrient uptakeArticle
