This article demonstrates the conclusions of an experimental field study on the influence of different types of fertilizers on the dynamics of growth and development of sunflower plants. In the course of the experiment, the characteristics of changes in biometric indicators of plants depending on fertilizer were studied. A comparative assessment of the influence of mineral fertilizers, biological preparations of growth-stimulating action, and the combination of mineral fertilizers with biological preparations on the yield of sunflower was carried out. The purpose of the research is to study the effect of the use of biological preparations with growth-stimulating action of the Bionorma line on the features of sunflower growth and development and its yield. The research was conducted at the experimental site of the Agronomichne Research Farm of the Vinnytsia National Agrarian University, located in the village of Agronomichne, Vinnytsia district Vinnytsia Region A mid-ripening linoleic hybrid of the French selection MAS 87.A was chosen for the field experiment; mineral fertilizers - ammonium nitrate (N60), double superphosphate (P60) and nitroammophoska (N60P60K60), as well as biological preparations: Bionorma Azot (nitrogen-fixing action), Bionorma Phosphorus (phosphorus-mobilizing action). The results of the study showed that the duration of the growing season of sunflower varied within 153-157 days, and the height of the plants was 135-183 cm depending on the fertilizers. The introduction of different types of fertilizers during the cultivation of sunflower practically did not affect the length of the growing season, where the difference in seed maturation was only 3 days. The highest height was reached by sunflower plants with the N30 + Bionorm nitrogen fertilizer option. All types of fertilizers ensured a high percentage of field germination of seeds and preservation of plants until the end of the growing season. The highest increase in the yield of sunflower seeds was provided by the application of half the norm of mineral fertilizers with biopreparations of the Bionorma line: N30Р30 + Bionorma nitrogen + Bionorma phosphorus - 22.0%. Application of Bionorm nitrogen + Bionorm phosphorus contributes to obtaining a yield increase of 15.8%, and Bionorm nitrogen – 13.5%
