The aim of the work is to study the effectiveness of the use of trace elements on potato varieties of different ripeness groups in the northern forest-steppe Ob in the Novosibirsk region. Experimental data were obtained on leached black soil of Novosibirsk region in 2017–2019. The generally accepted technology of potato cultivation was used for the experiments. Since autumn, fertilizers at a dose of P90K90 were applied as a general background for potatoes. Nitrogen fertilizers (60 kg / ha) were applied in the spring for pre-sowing cultivation. Foliar dressing with microelements (Cu, B, Zn) was used at the beginning of the budding phase of potato plants: copper – 20, boron – 45, zinc – 50 g of active ingredient per 1 ha with a working fluid consumption of 300 l/ha. Trace elements increased the growth and development rates of potato varieties of three groups of ripeness. In varieties Liubava (early), Svitanok Kievsky (mid-early), Tuleevsky (mid-season), the use of trace elements contributed to an increase in the development indicators of the photosynthetic apparatus (maximum and average leaf area and plant productivity) by an average of 21%, especially against the background of boron and zinc. Foliar dressing of potatoes increased the yield parameters by an average of 24 % relative to the control (water). The increase in the marketability of tubers reached 12 %. A greater effect was achieved against the background of boron use: a significant increase in yield, dry matter, starch, vitamin C. In variants with microelements, the susceptibility of potatoes by rhizoctonysis decreased.

The work aims to study the effectiveness of herbicides application on potato varieties of different ripeness groups in the conditions northern forest-steppe of the Novosibirsk Ob region. The authors obtained experimental data on leached chernozem in Novosibirsk district, Novosibirsk region, in 2017-2019. In their studies, the authors used common elements of potato cultivation tech- nology. The general background for potatoes in autumn fertiliser was applied at a dose of P60K90. Nitrogen fertilisers were used at a rate of 60 kg/ha in spring under pre-sowing cultivation. Herbicides Gezagard, Lazurit, Zenkor, Boxer, and mixtures of individual herbicides were applied before and after sprouting when potato plants were up to 12-14 cm high. Herbicides significantly reduced the infestation of potato varieties Lubava (early) and Tuleevsky (medium-season). The authors showed that the use of herbicides accelerated the processes of growth and development of potato varieties of two groups of ripeness. There was a significant increase in leaf area, photosynthetic potential, and 23-28% plant productivity. On a background of herbicides increase of yield by 30-35% is observed. There was an increase in the marketability of tubers by 10%. Used herbicides provided good quality and preservation of potato production. The authors note that the double application of herbicides Zenkor and Lazurit offers high rates of weed reduction. Thus yield and quality of presentation have high indicators. In tubers of potatoes, the residual quantity of herbicides is not detected. Application of herbicides economically and energetically practical. The level of profitability exceeds control 1,4 times on a background of double spraying by herbicides Zenkor and Lazurit.

Objective of the research: to study the influence of the norms of mineral fertilizers on the yield and quality of seeds of oil flax varieties in the conditions of the northern forest-steppe of the Tyumen region. The studies were carried out on the experimental field of the State Agrarian University of the Northern Trans-Urals in 2019-2020. The soil of the experimental field is leached chernozem, thin, heavy loamy. Experimental options included: control, without fertilizers; NPK based on seed yield 2 t/ha; NPK based on seed yield of 3 t/ha. Increases in yield from the use of fertilizers in the studied varieties August and Sokol were obtained in 2019, the growing season of which was characterized by the amount of precipitation close to the long-term level. In 2020, when there was a shortage of precipitation, only the Sokol variety showed a positive reaction to fertilizers. Under the influence of fertilizers, the seed oil content of the August variety decreased, while the Sokol variety was at the same level in all variants.

The State Agrarian University of the Northern Trans-Urals continues to breed spring wheat. Two varieties of Tyumen Jubilee and Tyumenochka have been created with the use of various source materials, including sources to the main cultural diseases in the region. Tyumenskaya variety has passed the State Variety Testing and is included in the Register of breeding achievements in 10 regions. The second variety is in the State Variety Trial. Research is continuing on both varieties to develop seed varieties. The results of influence of different levels of mineral nutrition on yield and quality of seeds of wheat varieties are analyzed in this report. It is established that in the northern forest-steppe zone of the Tyumen region on the natural fertility of leached black soil the average seed yield for three years was for the variety Tyumenskaya jubilee 2.48 t/ha, for Tyumenochka – 2.08 t/ha. In the variant with application of mineral fertilizers to the planned yield of 4 t/ha, the first grade seed was obtained 3.29 t/ha, the second – 2.91. The additions to the control variant were 0.81 and 0.83 t/ha. When applying mineral fertilizers to the yield of 5 and 6 t/ha, the additions remained at the level of the previous version, except for the Tyumenochka variety in the last version. The yield of seeds from the total yield in the control variant was 75.5 % for the variety Tyumenskaya jubilee and 71.7 % for Tyumenochka. In the variant with NPK by 4 t/ha the yield of seeds increased by 4.2 % in the first grade and by 4.5 % in the second grade. Protein content in the seeds of wheat varieties on the natural soil fertility was 13.6 and 12.3 %, respectively. The maximum content of 16.0 and 14.8 % is noted in the variant with fertilizers for the planned yield of 4 t/ha. In the same variant the highest germination energy (82.3, 80.1 %) and germination of seeds (96.9 and 95.5 %) are higher than the control variant by 20.7, 15.6 and 1.8 %; 2.5 % accordingly. The main part of the seeds (71.0 and 68.1 %) of the studied wheat varieties in the mentioned variant grew with 5–6 germ roots that is 19.3 and 13.2 % higher than the control. The variant with fertilizers for the planned yield of 4 t/ha was more economically advantageous, the level of profitability of the variety Tyumenskaya jubilee was 49 %, and Tyumenochka 44 %.

The productivity of agricultural crops is the most variable and integral indicator of their vital activity, which accumulates their genetic potential, soil fertility, weather conditions and components of agricultural technology. Soybean under optimal growing conditions (the reaction of the soil is close to neutral, sufficient phosphorus and potassium nutrition, the use of nitraginization) assimilates from the air about 70 % of the total nitrogen requirement. Therefore, it is believed that it is enough to apply only a starting dose of nitrogen fertilizers (20–40 kg/ha a. s.), to get a high yield with good indicators of grain quality. The results of studies of the influence of long-term (8 years) application of different doses and ratios of fertilizers in field crop rotation on podzolized chernozem in the conditions of the Right -Bank Forest-Steppe of Ukraine on the yield and quality of soybean seeds preceded by spring barley were presented. It was found that crop yields could be increased by 18–77 % owing to different doses, ratios and types of fertilizers. The highest indicators of seed yields for three years of the research (3,02 t/ha) were obtained under the application of mineral fertilizers at a dose of N110P60K80 per 1 ha of crop rotation area, including under soybean – N60P60K60. Exclusion of the nitrogen component from the complete fertilizer (N60P60K60) reduced its yield by 26 %, phosphorus – by 17, and potassium by 11 %. There was no significant decrease in soybean yield in the variant of the experiment with a decrease in the proportion of potassium in the composition of complete mineral fertilizer (N60P60K30) for three years of study. The largest mass of 1000 soybean seeds was formed at doses of N60К60 fertilizers, and their protein content — under the application of complete mineral fertilizer in doses of N60P60K60 and N60P60K30.

Introduction of complex mineral fertilizer of an azofoska in combination with ammonium nitrate and urea to early ripe potatoes of Zhukovsky and Red Scarlett variety on the planned productivity of 40 t/hectare has allowed to achieve a goal. At the same time in control option without fertilizers the productivity was 23,2-24,8 t/hectare. Use of encapsulated urea has led to decrease in productivity and level of profitability by 26,3-30,9%. Early ripe potatoes of Zhukovsky and Red Scarlett variety on natural fertility of the chernozem leached in the northern forest-steppe of the Tyumen region have created average yield of 23,2-24,8 t/hectare for years of researches. Use of complex mineral fertilizer of an azofoska in combination with ammonium nitrate and urea on the planned productivity of 40 t/hectare has led to increase in productivity on the first variety to 39,5 on the second variety up to 41,4 t/hectare. Introduction of the encapsulated urea has led to decrease in productivity of the early ripe potato tubers studied. At the same time, the peel was gentle and when cleaning it was strongly injured. As to the content of starch (11,9-12,6%) at both varieties the big difference between ex-perience options isn't revealed. The similar picture was observed also according to tastes of tubers. It has made 3,2-3,5 points at Zhukovsky variety and 3,4-3,7 points at Red Scarlett's variety. Profitability level in con-trol option at Zhukovsky variety was 157,3%, at Red Scarlett's variety – 140,5%. In options with non-encapsulated ammonium nitrate and urea the first variety got 172,6-184,1%, second variety – 190,4-207,2%. In option with encapsulated urea at varieties under study the profitability level has decreased 26,3-30,9.

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.

Among spring grain crops, oats are one of the main crops in Siberia. Taking into account climatic factors and production demands, breeding for increased productivity and adaptability to local natural and climatic factors, resistance to biotic and abiotic stresses appears to be currently relevant. This is a key factor for a permanent increase in both yield and quality of agricultural products. The aim of the study is to determine the group of adaptive oat varieties by the content of crude fat in grain for introduction into production and inclusion in breeding programs. The studies were carried out in the conditions of the southern forest-steppe of the Omsk Region during 2013-2018. The indicator of the range of crude fat content according to V.A. Zykin (d), index of ecological plasticity according to D.I. Baranskiy (O), homeostaticity according to V.V. Khangildin (Hоm), an indicator of intensity according to R.A. Udachin (I), the relative stability of the trait N.A. Sobolev (St²), an indicator of the level of stability of the variety according to E.D. Nettevich (PUSS) were calculated. The final assessment of adaptability was based on the sum of the ranks. The minimum range of crude fat content was observed in varieties Irtysh 23 and Fakel (d = 1.87 and 2.97%). Cultivars Irtysh 23, Tarsky 2, Fakel, Sibirskiy Hercules and Sibirskiy golozerny differed in plasticity (O = 6.4–13.6) and homeostaticity (Hom = 0.82). The variety Irtysh 13 (Hom = 0.23) was also homeostatic. The stability of the trait according to N.A. Sobolev characterized all varieties (St² = 0.94–0.99), according to E.D. Nettevich – Irtysh 13, Irtysh 23, Pamyati Bogachkova and Fakel (PUSS = 193.4-305.5%). Having an assortment of estimated indicators of adaptive parameters, it is advisable to apply the ranking and conduct the final assessment according to the sum of the ranks received by each variety. The varieties Irtysh 23 and Fakel (∑ ranks = 23 and 25) and Sibirskiy Holozerny (∑ ranks = 26) are the most adaptive in terms of the content of crude fat in grain for the conditions of the southern forest-steppe of Western Siberia.
