The article presents the results of experimental research on the influence of pre-sowing seed treatment and microfertilizer application on the structural elements of pea yield. During the experiment, changes in individual productivity indicators were investigated depending on the experimental variant. The aim of the research was to study the structural elements of pea seed yield and the specific effects of pre-sowing treatment and foliar fertilization on them. Field and laboratory studies were conducted on the experimental plots of the “Agronomic” Research Institute of the Vinnytsia National Agrarian University during 2022-2024. The experimental area is characterized by gray forest soils with a humus content of 2.0-2.2%. In the field experiment, medium-ripening varieties were used: the domestic variety Haiduk and the foreign variety Karen; biological preparations – Anderyz at 3 l/ha, Biomag- Horokh at 2 l/ha, Optimize Pulse at 3 l/ha; microfertilizers – Helprost Soy at 3 l/ha, Vuksal Microplant at 1 l/ha. According to the results of the conducted research, it was established that the use of biopreparations and microfertilizers had a significant effect on the yield structure indicators, although they largely depended on weather and climatic conditions. Overall, during 2022-2024, the average number of pods per plant for the Haiduk variety was 3.48, while for the Karen variety it was 3.35, and the weight of 1000 seeds was 232.5 g and 227.3 g, respectively. The maximum number of pods and the weight of 1000 seeds were formed in the variant where seed inoculation was done with the Optimize Pulse preparation and foliar fertilization was carried out during the budding phase with the Vuksal Microplant preparation, which amounted to 3.77 pods/plant and 255.5 g for the Haiduk variety, and 3.63 pods/plant and 247.1 g for the Karen variety. This is an increase of 20.8% and 21.9% for the Haiduk variety, and 20.1% and 21.4% for the Karen variety, compared to the control.
