The article presents the results of a three-year field study (2023-2025) to examine the effectiveness of the combined use of seed nanopriming and fertigation in the cultivation of the Myachkovsky 300 onion variety as an annual crop on alluvial meadow soils of the Moskvoretskaya floodplain. A two-factor experiment was conducted using the split-plot method, where factor A included five mineral nutrient backgrounds, and factor B included three seed treatment methods (control, priming with 0.25% ethanediol, and ethanediol with silver nanoparticles at 100 mg/L). A significant impact of meteorological conditions was found: the average yield ranged from 24.7 t/ha in 2024 to 26.5 t/ha in 2025. up to 46.8 t/ha in 2025. The use of N40P40K40 provided an increase of 7.1% relative to the control, the inclusion of fertigation increased this figure to 10.6-19.4%. Seed priming provided an increase in yield from 28.4 to 37.3% regardless of the nutrition background. Maximum efficiency was achieved with the integrated use of agricultural practices: in the N40P40K40 variant with fertigation according to scheme No2 (N 58.5; P2O5 15; K2O 51; CaO 5; MgO 5; S-SO4 10.75 kg/ha; Zn, Cu, Mn at 1 kg/ha each) in combination with seed treatment with ethanediol and silver nanoparticles, an average yield of 46.4 t/ha was obtained with an increase from priming of 37.3% and from fertilizers of 24.1%. In 2025, yields for this variant reached 60.3 t/ha. Statistical analysis confirmed the significant differences (LSD05 for factor A 5.3-6.0 t/ha, for factor B 9.1-9.7 t/ha). A trend toward increased plant resistance to bacterial diseases was noted when seed treatment with silver nanoparticles. The obtained results confirm the potential of using seed nanopriming in combination with fertigation to increase onion productivity in the Non-Chernozem zone.
