Over the past decade, nanotechnology caused the need for rigorous research on ultrafine nanomaterials which enhance productivity and quality of agricultural products. However, most studies are controversial; it is difficult to compare doses of nanoparticles and types of plants. In the experiment, nanoparticles of Fe (90–110 nm), Cu (50–110 nm) and Mo (100–120 nm) at four concentrations with a geometric progression were used to treat potato tubers. Germination energy was determined according to GOST 12038-84; the content of photosynthetic pigments was determined according to the method by N. D. Smashevsky (2011), phytotoxicity was determined according to the method by Kazev K. (2013). Thus, the data indicate that treatment of Solánum tuberósum L. tubers with iron nanoparticles stimulated the growth of the length of sprouts (55.1% and 21.4%), roots (34.4% and 12.5%) and chlorophyll a (57 - 98%) at a concentration of 0.0125 … 0.025 M. At the same time, copper and molybdenum nanoparticles are ineffective by the significance of their effects on plants.
