The article deals with the formation of the area of leaves of spring wheat depending on the treatment of seeds and varieties in the conditions of the Chuvash Republic. Three varieties of Margarita, Simbircite, and Prokhorovka were studied. The second factor is seed treatment in three gradations: 1. Without processing (control). 2. Seed treatment with the drug Benlate. 3. Seed treatment with Nano-Gro. The results of the analysis of leaves area formation are presented. Determining the optimal leaves area is a very complex problem. Solar radiation at an insufficient leaves area of field plants is absorbed not completely; at the greatest developed leaf surface the same phenomenon occurs. In combination with the seed protectant of spring grain crops – Benlate, the authors also studied the effect of Nano-Gro. The presowing treatment of seeds with the Nano-Gro solution significantly affects the increase in the formation of the leaves area of spring wheat.

The article examines the indicators of the structure of yields of spring wheat plants, depending on the variety in the conditions of the Chuvash Republic. The density of shoots is the first indicator of the structure of yield, which can be assessed visually. On its basis, it is possible to conduct a survey of crops, paying attention to the uniformity and amicability of emergence. According to the data (Makarova VM, 1995), in the conditions of the Non-Chernozem Zone, the optimum density of seedlings of grain crops should be considered no less than 400-500 plants per 1 m2 at the rate of sowing 6 million virgin grains per 1 hectare, while ensuring the field germination level 70 - 80%. It is known that not all seeded seeds are seedlings. Therefore, distinguish between laboratory and field germination. It should be noted that there is still a concept of the completeness of seedlings, which many people still understand as synonymous with field germination. During the vegetation the number of plants per unit area does not remain unchanged. Due to a number of reasons, attacks are observed in the crop, (Terekhov M.B., 2000). The survival rate of plants is the percentage of plants that have survived to harvest, or the ratio of the total or productive number of plants before harvesting to the number of shoots per m2.

The effectiveness of the insecticofungicide Prestige, KS, used to protect plants from damage by diseases and damage by pests in the first stages of ontogenesis is shown. Presowing seed treatment with a preparation with a flow rate of 2.5–3.5 l/t reduced the incidence of winter wheat with root rot of rhizoctoniosis etiology by 62.9%. The biological effectiveness of the Prestige, KS (3.5 l / t) on moderately infectious background was also quite high - 59.5%, however, it was 9.0% lower than the standard. It practically did not influence overwintering of plants. After application of Prestige, KS were in the norm of 2.5 and 3.5 l/t, and Maxim Extreme, KS in the norm of 1.75 l/t, the number of plants preserved by spring varied from 91.9 to 92.9%, that is higher than in the control by 3.9–4.9%. The application of insectofungicide Prestige, KS at a rate of 2.5 l/t on spring wheat sowings reduced the number of grain fleas by more than 80.0%and the damage of the stems by the larvae of cereal flies by 74.3%. This preparation  is not phytotoxic with respect to cereals.

The article discusses the formation of planting density and spring wheat crop structure depending on varietal characteristics and seed dressing in the conditions of the Chuvash Republic. Varieties Margarita, Simbirtsit and Prokhorovka were studied. The second factor is seed treatment in three grades: 1. Without treatment (control). 2. Seed treatment with Benlat. 3. Seed treatment with Nano-Gro. The results of the analysis of the formation of field germination of seeds, the safety of plants and elements of the structure of the crop 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 increases the formation of planting density, field germination and the structure of the spring wheat crop (Terekhov MB, 2000; Kodanev I.M., 1984; Makarova V.M., 1995; Shashkarov L.G., 2018; Tolstova S.L., 2018; Aleksandrova A.N. 2018). The formation of highly productive crops is influenced by field germination of seeds. At least 400-500 plants per 1 m2 should be considered the optimal density of seedlings of grain crops in the Chuvash Republic with a sowing rate of 6 million germinating grains per 1 ha, and field germination of 70-80% is achieved (Kodanev I.M., 1984). In our studies, the density of seedlings and field germination of seeds depended on both varietal characteristics and meteorological conditions that developed during the sowing - seedlings.

The influence of various levels of mineral nutrition on the accumulation of plant-root residues of spring wheat and oats in the conditions of the forest-steppe zone of Western Siberia is studied. The natural agricultural background of leached chernozem was taken as a control. The research was carried out at the station of the Department of Soil Science and Agrochemistry of the State Agrarian University of the Northern Trans-Urals. In the experiment, various doses of mineral fertilizers were used, ensuring the yield of grain crops from 3.0 to 6.0 t/ha. It was found that the mass of plant-root residues of spring wheat and oats has no significant differences and depends on the level of mineral nutrition. On the natural agricultural background, the mass of plant-root residues is 3.24-3.88 t/ha. Fertilization increases the yield of grain crops to 6.0 t/ha, and also increases the amount of plant-root residues: spring wheat - 4.47; oats – 6.04 t/ha. Increasing the doses of mineral fertilizers reduces the ratio of yield to the mass of plant-root residues from 1:1.6 to 1:1.10 units. It was found that almost half of the root system of spring wheat and oats is located in a layer of 0-10 cm, while the share of roots in a layer of 30-40 cm accounts for no more than 16% of the mass.

The effects of seed treatment with imazalil at 0.2 and 0.3 g a.i./kg seed on subcrown internode length and occurrence of coleoptile-node-tillers (CNT) was studied in four spring wheat cultivars at two locations in Saskatchewan. Without treatment, Cypress had the longest internodes followed in descending order by Glenlea, Neepawa, and Wascana. Generally, plants from imazalil-treated seed had significantly shorter subcrown internodes. Only a few plants from nontreated seed produced CNT and of these, many were soft or aborted, while the treated seed produced a number of CNT and many of these were firm tillers. The possible importance of these morphological changes in the reduction of common root rot, on drought resistance, cold hardiness, and yield is discussed.
