Wheat is the main and most important food crop in most countries of the world. It is cultivated in more than 80 countries. The purpose of the work was to study the effect of the growth stimulator Agrostimulin on the sowing traits of wheat seeds. The growth regulator Agrostimulin promotes accelerated division of plant cells, the development of a more powerful root system, an increase in the leaf surface area and chlorophyll content, reduces the phytotoxic effect of pesticides, has an antimutagenic effect, improves the quality of grown products, increases productivity, plant resistance to diseases, stress factors, resistance to adverse environmental factors (hypothermia, overheating, lack or excess of light and moisture). Its use makes it possible to reduce the rates of application of pesticides when using the drug 3–5 times during the vegetation period. The use of the growth stimulator Agrostimulin in the cultivation of spring wheat Omskaya 36 has been reflected in the article. Studies on the sowing traits of spring wheat seeds, phenological observations have been carried out. The yield of wheat Omskaya 36 variety with the use of the growth regulator Agrostimulin was 20 c/ha, which was by 2,1 c/ha or 11,7 % higher compared to the previous year. It has been revealed that the length of the vegetation period in wheat treated with the growth regulator Agrostimulin was 89 days, which was by 7 days less compared to the control. Thus, it has been experimentally proved that the treatment of spring wheat seeds Omskaya 36 with the growth regulator Agrostimulin shortens the growing season and increases its yield.
