Treatment of plants with a bioeffector (BS) and humic fertilizer (HD) stimulated photosynthetic processes, ensuring the content of pigments at the level of 2.31-2.37 mg/g of raw material in the spring tillering phase and up to 3.59-3.82 mg/g at the earing stage. Accordingly, an increase in the net productivity of photosynthesis was noted: from 4.90-5.12 g/m2 per day in the spring tillering phase to 8.90-9.14 g/m2 during the earing period. By the end of the growing season, photosynthetic processes fade. Biologized fertilization systems increased the biological potential of winter wheat, ensuring improved growth, increased content of Ca and Mg in leaves; weight of grain per ear and weight of 1000 grains. Accordingly, BSU ensured a yield of 5.34-5.88 t/ha. Product Description popup.authors Oksana Y. Kachmar Anhelina O. Dubytska Maria Shcherba popup.nrat_date 2025-12-19 Close
