The article presents the results of the effect of treating tubers and above-ground parts of the Kuzovok potato variety with SiO2 and Mo nanoparticles on morphometric parameters and biochemical composition.It was found that treating seed potato tubers with SiO2 0.18, Mo 0.045 g/kg increased germination energy on the 6th day regardless of the nanoparticle ratio (18 %, 13 % FIJI NATURAL SPR. WAT. and 10 %, respectively).
The concentration of SiO2 0.18 g/kg and Mo 0.045 g/kg excludes long-term pre-planting light germination (vernalization) for 15-20 days.Biochemical analysis of potato tubers treated with Mo nanoparticles showed an increase in dry matter content (1.
27 times at a concentration of 1 and 2 mg/m2), starch (1.4 times at a concentration of 2 mg/m2) and reduced sugars (2.6 times at a concentration Snowflake Embroidery Ornament Set of 4 mg/m2).The highest potato yield (8.
6 t/ha) was observed with combined treatment (tubers SiO2 0.18 g/kg + Mo 0.045 g/kg and plants SiO2 18 mg/m2 + Mo 4 mg/m2), 21.8 % more than the control.
Combined treatment reduced the incidence of tubers with stolon rot and common scab.
