Over the course of two vegetation seasons of winter rape cultivation, a comprehensive assessment of the fertilization effectiveness was carried out for various foliar fertilization options using complex chelated micronutrient fertilizers at the budding stage. An innovative physiological indication method was applied, based on the induction of chlorophyll fluorescence with detailed analysis of the Kautsky curve and determination of its core parameters such as F0 – minimal (initial) fluorescence, Fpl – fluorescence induction 'plateau' value, Fm – maximal fluorescence, Fst – steady-state fluorescence, as well as nine derived indicators calculated on their basis within a unified methodological analysis cycle. Graphical interpretation of the results was carried out with the construction of averaged chlorophyll fluorescence induction (CFI) graphs for each variant of micronutrient fertilizer application. A summary table of derivative indicators based on the standard European protocol for chlorophyll fluorescence analysis was compiled, emphasizing its importance for evaluating the physiological condition of plant organisms. It was determined that winter rape plants exhibit a distinct response to the optimization of mineral nutrition conditions, including foliar fertilization systems. This allows the identification of the optimal variant both in terms of predicted productivity increase and enhancement of plant adaptability and stress resistance, as well as development of an efficient photosystem and realization of the plant's genetic potential. It was found that various micronutrient fertilizers significantly affect photosystem activity and its efficiency, with a range of 5.5% to 26.4% among the tested fertilizers. This provides grounds for identifying specific types and subtypes of fertilizers based on nutrient ratios and chemical composition. Based on this comprehensive evaluation, it was concluded that among the three tested micronutrient fertilizers—Avangard Rape, Yarilo Oilseed, and Helprost Rape—the application of Helprost Rape demonstrated the highest physiological efficiency in supporting the functioning of the assimilation surface and improving plant stress resistance and adaptability.
