Studies of different content of magnesium nanoparticles in combination with stabilizers polyvinylpyrrolidone (PVP) and collagen hydrolyzate (GC) on the effect on the growth processes of spring wheat plants were conducted. It was found that the most positive effect on germination was produced by magnesium preparations in the following concentrations Mg 10 mg + PVP with a rate of 5 ml/t, Mg 20 mg + PVP with a rate of 1 ml/t, Mg 10 mg + GC with a rate of 1 ml/t. The initial growth and development of the root was significantly affected by the variant No3 Mg 10 mg + Ag 1 ml + PVP at the rate of 1 ml/t, and the development of the sprout was affected by all magnesium nanosets at the rate of 1 ml/t. When analyzing the assessment of plant development on days 7, 10 and 15, it was found that magnesium preparations with collagen stabilizer (GC) had a positive effect. Treatment with magnesium preparations on vegetative parts of plants, namely daily sprouts determined the effective rate of the preparation of 5 ml and more. The high values were in the variants Mg 20 mg + PVP, Mg 10 mg + Ag 1 ml + GC, where the increase in sprout length was 2.7-2.9 cm, weight 1.0-1.3 g.

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.

In the climatic conditions of the Central Black-earth region, the infection of wheat grain with Fusarium fungi is of latent nature and can only be detected by mycological analysis. For this reason, the varietal composition of the pathogenic complex of fungi Fusarium on winter and spring wheat has not been thoroughly studied yet. Working with the problem in the conditions of the Tambov region, it was found that the grain of these varieties was infected with various species of Fusarium. The most infected spring wheat varieties were “Nik” (69%), “Biora” (45%) and “Prokhorovka” (30%). The varieties “Saratovskaya 29” (4%) and “Tulaikovskaya 100” (5%) were less infected than the other. Nine species of fungus Fusarium spp. found on spring wheat seeds were F. acuminatum Ellis, an Everhart (1895), a Wollenweber (1917), F. avenaceum (Corda ex Fries) Saccardo (1886), F. culmorum (WG Smith) Saccardo  (1895), F. equiseti (Corda) Saccardo (1886), F. poae (Peck) Wollenweber in Lewis (1913), F. sambucinum Fuckel (1869), F. semitectum Berkeley and Ravenel in Berkeley (1875), F. sporotrichioides Sherbakoff (1915) and F. tricinctum (Corda) Saccardo (1886). The leading position was occupied by the species Fusarium sporotrichioides and F. avenaceum. The frequency of their occurrence on spring wheat seeds was 56.6 and 20.9%, respectively. The contamination of winter wheat with a Fusarium fungus was lower than the infection of spring wheat (1–8%). Four species of Fusarium spp. were identified on the seeds of winter wheat, they are F. avenaceum (Corda ex Fries) Saccardo (1886), F. graminearum Schwabe (1838), F. poae (Peck) Wollenweber in Lewis (1913) and F. sporotrichioides Sherbakoff (1915). The dominant position belonged to the species Fusarium poae and F. sporotrichioides (41.7 and 37.5%). It has been shown that the level of infection of wheat seeds by Fusarium fungi depends on the variety resistance to the infection.

The results of assessing the effect of biological preparations and a seed disinfectant on the technological qualities of grain of soft spring wheat Novosibirskaya 31 are presented. The effectiveness of the use of biological plant protection products was studied in the field experiment, laid down in 2020 in the forest-steppe conditions of the Ob region. Pre-sowing seed treatment included the following options: control (without treatment); Trichodermin, P (Trichoderma viride, titer more than 6 billion spores/g), consumption rate – 15 kg/t seed; Sporobacterin, SP (Bacillus subtilis + Trichoderma viride, strain 4097), consumption rate – 0.5 kg/ton of seeds; Scarlet, ME, chemical standard (imazalil (100 g/l) + tebuconazole (60 g/l), consumption rate – 0.3 l/t of seeds. The use of the preparations contributed to an increase in yield by 0.40 and 0.52 t/ha when using Trichodermin and Sporobacterin, respectively, and by 0.08 t/ha when using fungicide Scarlet. In this case, the mass of 1000 grains increased by 0.84, 0.80 and 0.96 g, respectively, relative to the control. The preparations Trichodermin and Sporobacterin had a significant effect on the growth of grain in length and width relative to the control – by 5.4-6.9 and 9.6%, Scarlet – by 10.6 and 13.9%, respectively. Pre-sowing seed treatment contributed to the growth of such indicators of the caryopsis as volume (by 19.6–29.3%), surface area (by 12.1–19.2%), and sphericity (by 6.3–7.8%). To a greater extent, they increased with the use of fungicide Scarlet. Getting larger grain led to an increase in the endosperm content by 0.76–1.14%. A close correlation has been shown between the indicators of the mass of 1000 grains and the linear grain sizes (r = 0.92–0.98), as well as with the grain volume, sphericity and endosperm content (r = 0.98–0.99). Pre-sowing treatment of spring wheat seeds provides grain with improved technological properties.

The article presents the results of studies on the formation of the crop, sowing qualities, yield properties and biochemical composition of seeds of spring soft wheat (Tulaykovskaya Nadezhda variety) under the influence of complex liquid fertilizers with microelements in chelate form in the conditions of the forest-steppe zone of the Middle Volga. The application of mineral fertilizer Megamix increased the number of grains on one plant to 32.9–36.3 units, which exceeded the control by 1.1–4.5 units, or by 3.5–14.1%. The yield of spring wheat from the integrated application of the agrochemical increased to 3.90 t / ha, which is 21.1% higher than the control.

The article discusses the issues of root rot, leaf and stem diseases (septoria, powdery mildew, rust) during tillering-exiting the tube, fusarium and smut during heading, depending on varietal characteristics and seed dressing in the conditions of the Chuvash Republic. Margarita, Simbirtsit and Prokhorovka varieties were studied. The second factor is seed treatment in three grades: 1. Without treatment (control one). 2. Seed treatment with Benlat. 3. Seed treatment with Nano-Gro. The results of the analysis of lesions by root rot, leaf and stem diseases (septoria, powdery mildew, rust) during tillering-exiting the tube, fusarium and smut during heading are presented. The effect of Nano-Gro in combination with the seed dresser Benlat was also studied. It has been shown that pre-sowing treatment of wheat seeds with Nano-Gro solution helps to reduce damage by root rot, leaf and stem diseases (septoria, powdery mildew, rust) during tillering-exiting the tube, fusarium and smut during ear formation in spring wheat.
