The paper studies the influence of magnetite nanoparticles stabilized with albumin on the ontogenesis and morphometric parameters of Zea mays L. As a result of the experiments, the concentration of nanoparticles was detected, which has a stimulating effect on the growth energy and entry of Zea mays L. seeds. It was found that when exposed to magnetite nanoparticles with a concentration of 2,4 mg/ml, the energy of seed germination increased by 36%, germination increased by 64%, the length of seedlings increased by 24%, and the root length increased by 78%. Under the influence of vibration (10 Hz frequency) in the experimental group with a concentration of 2,4 mg/ml nanoparticles, the root length increased by 25%, the root diameter decreased by 14%, the stem length decreased by 2%, and the stem diameter decreased by 1%. In the group with a concentration of 1,6 mg/ml, the stem diameter increased by 8%. It was reliably established (p<0,05) that the highest indicators of germination energy and germination of Zea mays L. were observed in the group with a concentration of magnetite nanoparticles of 2,4 mg/ml. It is recommended to use magnetite nanoparticles with a concentration of 2,4 mg/ml without vibration as a growth stimulant for Zea mays L.
