The assessment of productivity and the parameters of adaptability allowed to use and perspective mid-season and mid-late varieties of spring wheat in the conditions of the Northern Trans-Ural region carried out. The varieties were tested in 2014-2016 on the steam predecessor in three climatic zones: subtaiga (II zone), northern forest-steppe (III zone) and southern forest-steppe (IV zone). The greatest interaction a genotype-environment is noted when calculating correlation dependence between productivity of varieties in various years of their test in the conditions of the southern forest-steppe zone (from r=-0,07±0.28 to r=0,41±0,25). Assessment of productivity and parameters of adaptability of spring wheat varieties in 9 environments (3 years x 3 GSU) has shown that Aviada allowed to use characterized the greatest maximum and average productivity in group of mid-season varieties (respectively 5,86 and 3,78 t/hectare), and in the mid-late group – a perspective Quintus (respectively 6,98 and 4,58 t/hectare). The considerable variability of productivity is noted.  Its size was from 23,0 % (Ikar) to 29,9 % (Aviada) in group of mid-season varieties, and at the mid-late group – from 25,6 % (Riks) to 31,6 % (Quintus). Resistance to stress of varieties was low irrespective of group of their ripeness. Ikar (-2,32) had the greatest indicator of resistance to stress in group mid-season varieties, and in the mid-late group – Riks (-2,54). Aviada (4,24 t/hectare) was characterized the greatest average productivity in contrast conditions in mid-season group and in the mid-late group – Quintus (4,73 t/hectare). Three groups of varieties were allocated on responsiveness for change of conditions:  high responsiveness (mid-season – the Lutescens 70, Aviada; mid-late – the Melody, Quintus), plastic (mid-season – Chernyava 13, Skent 3, Omskaya 36, Tyumenskaya 25, Tyumenskaya 29; mid-late – Ingala, Yamalskaya) and poorly responsiveness (mid-season – Ikar, Sigma; mid-late – Riks, the Stepnaya Niva). The low gomeostasis is revealed at all varieties irrespective of group of ripeness. The variety Ikar (Hom=6,59) was the best on a gomeostasis in mid-season group, and at the mid-late group – Riks (Hom=5,48). In general all varieties were characterized by the low general adaptive ability (GAA). Its rather high values in group of mid-season varieties are revealed at Aviada (OAC=0,19), and at the  mid-late group – Quintus (OAC=0,50). Tyumenskaya 25 and Tyumenskaya 29 are recognized the best mid-season varieties in the conditions of the Northern Trans-Ural region on the basis of complex assessment of productivity and parameters of adaptability, and at the mid-late group – Melody and Ingala.

On the basis of summarizing the results of many years of experience about environmental study of varieties and breeding varieties of spring wheat, we revealed the peculiarities of influence of plants’ assimilation apparatus parameters on the productivity level of early ripening, middle- and late ripening varieties in the forest-steppe zone of Orenburg Urals. These varieties should be used to create hybrid forms of spring wheat with optimal parameters of photosynthetic surface. This will better in solution the selection issues on efficiency in the forest of the Southern Urals. As a result, during the study of the influence of the size of the surface to the grain photosynthetic productivity level of wheat varieties, we found that in this case with an increase in the parameters of the assimilation apparatus, there is an increase of yields up to a certain limit, then a further increase in the size of the photosynthetic surface leads to lower yields. This pattern is clearly related to the fact that the overgrowing foliage due to worsening conditions for leaf photosynthetic activity, the rate of photosynthesis decreases. The following studied varieties of spring wheat have optimal parameters of the photosynthetic index: Volgouralskaya, Varyag, Kinelskaya 59, Logachevka, Lyuba, Prokhorovka, Solveig, Tulaykovskaya 1, Tulaykovskaya stepnaya and Enita. These varieties should be used to create hybrid forms of spring wheat with optimal parameters of the assimilation apparatus.

The authors studied the effect of the bacterial-humic preparation AFG-b containing the spore-forming bacteria Bacillus subtilis and Bacillus amyloliquefaciens in a production experiment in the northern forest-steppe of the Novosibirsk Priob’ye region. The preparation was used on midearly spring wheat, which forms grain at the level of valuable wheat. The drug was used as an antistressant together with herbicides against dicotyledonous and monocotyledonous plants. The tank mixture used was metsulfuron-methyl, fenoxaprop-P-ethyl with the antidote cloquintoset-mexyl and 2-ethyl hexyl ester of 2,4-D with florasulam. The bacterial-humic preparation AFG-b is known to level out herbicide stress in wheat and improve plant health. It improves the condition of leaf cell membranes by preventing the escape of electrolytes from the cells. On the roots of plants one month after applying the antistressant, the authors observed a 1.5-2 times reduction in the development and prevalence of root rot of fusarium-helminthosporiosis etiology. The authors also marked the most pronounced phytosanitary effect of the preparation’s bacteria, which are antagonists of phytopatho- gens for plants’ primary roots and epicotyl. An increase in plant productivity manifests the anti-stress and growth-stimulating effect of AFG-b. During the growing season of 2020, the bio preparation combined with herbicides provided a reliable increase of 40.2% of the grain of spring wheat and improved its quality by enhancing the protein and gluten content. Under 2019 conditions, AFG-b increased grain yield relative to herbicides by about 8% and did not affect grain quality. Application of AFG-b as an anti-stressant is not accompanied by improvement of seed quality of the new crop. It does not improve its phytosanitary status in infestation by phytopathogens Bipolaris sorokiniana, Fusarium sp., Alternaria, Stagonospora nodorum, Penicillium and Aspergillus relative to herbicides alone.

The results of studying resistance of mid-ripening spring wheat cultivars to root rot in the forest-steppe zone of Irkutsk region are presented. The study was conducted in a two-factor field experiment. Factor A – mid-ripening spring wheat cultivars: Tulunskaya 11 (control), Zoryana, Маrsianka, Stolypinka (new cultivars). Factor B – seeding dates: May 10, 20, 30, preceded by fallow. The experimental plot area was 70.0 m2. The experiment was repeated three times. Plot arrangement was randomized. Root rot prevalence was determined during the tillering phase of the crop. In 2018, the sowing dates did not affect the disease due to the long spring-summer drought (May-June) and a higher average daily temperature compared to long-term average values. In arid and cold conditions of May 2019, with the late sowing period (May 30), root rot prevalence was significantly lower than when sowing on May 10 and 20. In 2019, a higher level of the disease was registered than in 2018 by 14.3%. Significant differences in root rot prevalence in both years of research were noted between the control cultivar Tulunskaya 11 and the new cultivars of spring wheat Zoryana and Stolypinka. In the tillering phase of the latter two, disease indicators were lower by 5.6% and 10.5% in 2018, and by 8.8% and 7.9% in 2019, respectively. Маrsianka cultivar was at the control level for this indicator. The best cultivar under study was Stolypinka, which was not only less affected by root rot, but also gave a statistically significant yield increase of 0.16 t/ ha in 2018 and 0.22 t/ha in 2019.

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.

Abstract The purpose of the research is to study the effect of the fungicide Lamador and the humic preparation Rostok on the quality of spring wheat and spring barley in the conditions of the northern forest-steppe of the Tyumen region. According to the yield, we found that pre-sowing seeds treatment with Lamador protectant and joint treatment with Rostock contributed to an increase in yield by 0.70 t/ha of spring wheat and 0.15 t/ha of spring barley, in the option with the pre-sowing seeds treatment with Lamador protectant and Rostock preparation by 0.90 t/ha and 0.10 t/ha. The highest yield of spring wheat was noted in the third option – 4.10 t/ha, of spring barley in the second option – 3.52 t/ha. An increase in the thousand kernel weight was noted in the crops under study. The highest thousand kernel weight was observed for spring wheat and spring barley in the third option – 30.2 g and 54.3 g, respectively. The maximum protein content in the spring wheat grain was noted in the third option –13.3%, which is higher than the control option by 1.3%, for spring barley we also noted protein increase by 0.4-0.5%. Thus, the experimental application of the fungicide Lamador together with the preparation Rostok for wheat seeds treatment demonstrated a positive effect of the protectants on plants in the agro-climatic conditions of the forest-steppe zone of the Tyumen region and contributed to an increase in crop yield by 28% for spring wheat and 4% for spring barley, which proved the need for their use in the plant protection system, to increase the productivity and quality of the grain obtained.

he effect of sowing multiple-nutrient mineral fertilizerapplication on spring wheat crops of the Astrid variety on gray forest soils of the forest-steppe zone was found. The study of the weather conditions of the growing season showed that the total amount of precipitation during the growing season was significantly lower than the average annual -158 mm as compared to 220 mm of the normal. The monthly rainfalls sharply differed from long-term ones; this had a significant impact on the formation of yield and grain quality. The application of NPK fertilizer and ammoni-um-phosphate-sulfate at a rate of 100 kg ha and ammoni-um phosphate fertilizer at a rate of 50 kg ha increased the yield of spring wheat grain by 8-66%, and the gluten con-tent in the variant with ammonium phosphate fertilizer at the level of 26-31% ascompared to 28% in the control. The payback of 1 kg of the primary nutrient of the fertilizers by grain yield gain was the highest against the background of NPK fertilizer and ammonium-phosphate-sulfate -55.0 and 40.8 kg, respectively. The protein content in wheat grain for in all fertilization variants ranged within 13.1-15.2% as compared to 13.7% in the unfertilized variant. The thou-sand-kernel weight as a result of obtaining high gains in the variants of sowing application ranged within 31.1-38.3 g; TKW below the control was in the variants with ammonium phosphate fertilizer and ammonium-phosphate-sulfate -31.1 and 33.4 g. The grain-unit belonged to Class 3 (no less than 730). It has been found that it is agronomically efficient when cultivating soft spring wheat in a temperately moist zone, on more arid years, on gray forest soils, when sowing, to apply NPK fertilizer and ammonium-phosphate-sulfate at a rate of 100 kg ha.
