Summary: The 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 hybrid plants. During the experiment, the characteristics of changes in biometric indicators of plants depending on fertilizer were investigated. A comparative assessment of the influence of mineral fertilizers on the yield of sunflower was carried out. The purpose of the research was to study the influence of mineral fertilizers (nitroammophoska, ammophos) on the growth and development of sunflower 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 of Vinnytsia region. For the field experiment, hybrids of the Swiss selection Sumiko, Alcantara and the French selection LG 59580 A were chosen; mineral fertilizers - nitroammophoska (N60P60K60) and amphos (NH4)2HPO. Based on the assessment of the hydrothermal regime of multi-term sunflower crops, the possibility of using sunflower in variants with mineral nutrition was analyzed. The general stress resistance and adaptability of this species to use in variants of different application of mineral fertilizers were determined. The role of hydrothermal conditions during the growing season on the formation of the biochemical components of the yield was evaluated, which ultimately made it possible to formulate prognostic options for the formation of the indicator depending on the variability of weather conditions, the dynamics of the formation of the amount of precipitation and the level of average daily temperatures. Conclusions were made regarding the value of sunflower for multipurpose use on gray forest soils in conditions of unstable moisture, which allows for the development of agro-technological solutions in the field of using sunflower as the main oil crop on the basis of this.
