Abstract

The purpose of the study was to evaluate the effect of foliar fertilisation systems and seed treatment on the productivity and physiological development of the facultative wheat variety Zymoyarka under the soil and climatic conditions of the Polissia region. The research was conducted in 2025 on the experimental field of Polissia National University using a randomised block design with four fertilisation variants. The methodology included pre-sowing seed treatment with GROS Korenerist, foliar applications of ECOLINE Phosphite (K), ECOLINE Boron (organic), and POLYACTIVE Boost, biometric and phenological observations, laboratory assessment of grain quality, and statistical analysis by ANOVA and correlation methods. It was established that the combined application of GROS Korenerist and ECOLINE Phosphite (K) significantly increased yield to 3.46 t/ha (+40.6% compared to control), improved root system depth to 8.5 cm, and enhanced root biomass to 1.59 t/ha. The positive correlation (r = 0.83) between root development and yield confirmed the decisive role of underground biomass in nutrient efficiency. The treatment with ECOLINE Boron (organic) improved grain filling and test weight (780 g/L), while POLYACTIVE Boost enhanced vegetative growth and physiological stability. Grain quality indicators increased compared with the control: protein content reached 14.2%, gluten – 30.5%, with a reduction in disease incidence by 15-25%. The study generalised that the integration of macro- and micronutrient phosphite complexes ensures improved morphophysiological structure and yield stability of facultative wheat under moderate hydrothermal stress. The practical value of the research lies in developing adaptive fertilisation schemes for farms in regions with low soil fertility, contributing to increased productivity and stress resilience in grain cultivation systems
