Abstract. For the further intensification of the processes of agricultural crop production, the permanent development of new preparations with effective growth-regulating activity in relation to crops and exhibit the ability to suppress phytopathogens and improve the quality of economically valuable products is required. The purpose of the investigation was to study the effect of pre-sowing treatment of wheat seeds with calcium polysulfide (CaS4) preparations on germination, plant productivity parameters, and grain quality. Methods. In laboratory conditions, the effect of calcium polysulfide on the germination of wheat plants was investigated. 0.1; 0.5 and 1 % of CaS4 solutions for incubating the seeds during 1, 2 and 3 hours were used. Fresh and dry mass, shoot and root lengths, as well as the rate of formation of superoxide anion and hydrogen peroxide content, were determined, peroxidase and catalase activity and malondialdehyde (MDA) concentration ware detected. Infield studies seeds were treated with CaS4 solution at a rate of 0.6 l/t, followed by determination of the number of seedlings affected by root rot. Results. As a result of one-hour presowing treatment of seeds with a 0.1% solution in six-day-old seedlings, an increase in leaf length was observed, as well as a beneficial effect of the drug on the redox system of root tissues. The use of CaS4 solution for pre-sowing treatment and during heading in the field increased the yield by 3 quintals/ha and increased the protein content in wheat seeds by 8–9 %. A conclusion is drawn on the effect of calcium polysulfide on the germination of wheat seeds depending on the concentration and time of pre-sowing treatment.

Keywords: wheat; pre-sowing treatment; calcium polysulfide; redox system; productivity.
