The article presents the results of the influence of the magnitude of heterosis on the main elements of the formation of yield (grain size and productivity of the main spike) of spring wheat in the Irkutsk region. The following were used as maternal varieties: Irgina, Krasnoyarskaya 83, Tulun 15, Tselinnaya 60, Altayskaya 92, Niva 2 and a variety from Mongolia Orkhon 85, as testers - Skala, Angara 86, Tulunskaya 12 The best indicators of hypothetical heterosis were manifested by the number of grains in ear in combinations Krasnoyarskaya 83 × Angara 86, Krasnoyarskaya 83 × Skala, Altai 92 × Skala (81.6 ... 85.7%). In terms of grain weight from the main spike, the best results of hypothetical heterosis were noted in hybrid combinations Krasnoyarskaya 83 × Angara 86, Orkhon 85 × Angara 86, Ni-va × Angara 86, Altai 92 × Angara 86 (100.0 ... 130.7%) ... Krasnoyarskaya 83 × Angara 86, Altai 92 × Angara 86, Or-khon × Angara 86 are recognized as the best hybrid combinations that can give the greatest yield of transgressive forms of elite plants.

Spring wheat is the main grain crop. Stable production of high-quality wheat grain is the key to the country's food independence. Therefore, the study of the elements of growing spring wheat technology, aimed at increasing the productivity of crops, is important. The study of the interaction of plants and microorganisms depending on the level of mineral nutrition in crop planning is currently ofparticular relevance. The use of biological products, growth regulators improves the mineral nutrition of plants, increases productivity and its quality, and also provides savings in mineral fertilizers. In the upper Volga region, the main spring crops are wheat, barley and oats. To further increase them in the region, it is necessary to study the characteristics of the formation of yields and determine the most productive crops depending on the level of nutrition, biological products and growth regulators. The scientific article presents the results of the study of these drugs on the productivity of spring wheat. In field experiments, it was planned to get 30, 40 and 50 tons of grain per hectare. Fertilizers for the planned harvest were made taking into account the agrochemical properties of the soil. From biological products used Flavobacterin, which has a protective effect against diseases and improves product quality, from growth regulators used agrochemicals HUMATE + 7 (10 % liquid concentrate), which is characterized by high biological activity. The yield level was determined taking into account the average long-term moisture supply and qualitative assessment of arable land. The indicators of photosynthetic activity of crops, crop and its structure, quality characteristics of grain and economic efficiency of growing spring wheat in the upper Volga region are presented. As a result of researches the optimum level of mineral nutrition for wheat, the efficacy of agrochemical diazotroph and programming yields of spring wheat, determined the photosynthetic activity of crops and grain yield, calculated economic efficiency of the studied techniques and established the qualitative characteristics of the crop. The program for obtaining the planned wheat yields in the years of the experiments was completed by 68-91 %. Close to the planned the program was implemented using a biological product and growth regulator-74-91 %.

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.
