Intensive development of nanotechnologies makes it viable to determine the influence of nanocompounds on the productive properties of crop plants, considering the environmental factors due to current climate change. The presented study aimed to investigate the effects of silver nanoparticles on the seeds’ ability to germinate, variability of morphophysiological traits during the vegetation period, and grain yield of spring soft wheat (Triticum aestivum L.). The wheat’s pre-sowing seed treatment with silver nanoparticles (silver nanoparticles in aqueous solution of 0.5%, 1.0%, and 1.5%) reached evaluation for variations in morphophysiological traits in three cultivars, viz., Omskaya-36, Tyumenskaya-29, and Novosibirskaya-31. All the seed treatments, carried out once, had the seeds kept in prepared solutions for three hours, as well as, the control (in distilled water only). Field experiments took place in 2018–2020 at the biostation ‘Lake Kuchak’ of Tyumen State University, Tyumen, Russia. Seed treatment (Ag 1.0%) contributed to an increase in field seed germination in the cultivar Omskaya-36 (by 23.8%) during 2019. For grain yield, positive results occurred in the cultivar Omskaya-36 (by 23.8% compared with the control) in 2019–2020, while in Tyumenskaya-29 (by 25.9%) in all years of the study, and cultivar Novosibirskaya-31 (by 12.8%) in 2019–2020.
