Over the past decade, nanotechnology has led to the need for rigorous research on ultrafine nanomaterials, which increase productivity and quality of agricultural products. However, most studies are extremely controversial regarding the effect of nanomaterials on the seed germination rate, the growth of the roots and the aerial parts of plants, or it is difficult to compare both in doses and dimensions of nanoparticles, and in types of plants. In the experiment, nanoparticles of Fe (90-110 nm), Cu (50-110 nm) and Mo (100-120 nm) in 4 concentrations with a geometric progression were used. Germination energy and germination were determined according to GOST 12038-84, the content of photosynthetic pigments according to the method of N. D. Smashevsky (2011), phytotoxicity according to the method of Kazeev K. (2003). Thus, the data obtained indicate that the treatment of Solánum tuberósum L. tubers with iron nanoparticles stimulated the growth of sprout length (55.1% and 21.4%), roots (34.4% and 12.5%) and the content of chlorophyll a (57 - 98%) relative to the control at a concentration of 0.0125 … 0.025 M. At the same time, the nanoparticles of copper and molybdenum by the significance of their effects on plants turned out to be ineffective.
