The socio-economic realities of today force to look for development ways at the expense of internal resources. The deployment of local systems is perspective at the regional level, because they based on the traditional economic patterns of ethnic communities inhabiting the region. Ethnoeconomical patterns are the relevant model for the geographical, spatial and socio-cultural conditions in which they were formed. This fact allows us to highly evaluate their potential. This article attempts to assess the prospects for the development of the ethnic economy of a region Khakassia. Author uses statistical data and materials of sociological survey of ethnic communities of the region (Russians, Khakass people and Shors). They have the greatest influence on the vector of ethnoeconomical development of the republic. The peculiarity of the ethnic economy of Khakassia is the high role of households of the population. They play a significant role in the agricultural sector. They produce a large amount of both vegetables and meat products. There are various programs aimed at supporting the livestock industry for both peasant (farmer) farms and personal subsidiary farms at the regional level. Representatives of the titular ethnic group (Khakass people) and indigenous small-numbered peoples (Shors) generally remain focused on traditional economic practices: cattle breeding and crafts. Author concludes that the support of the distinctive types of economic activities of these ethnic groups is necessary not only from the point of view of economic expediency, but also for the preservation of the culture of these people.

Relevance. Sugar beet is one of the raw materials from which granulated sugar is produced, and it, in turn, is one of the indicators by which the food security of any country is assessed. In 2020, European countries produced 47.6% of the total global volume of sugar beet, Asian countries — 18.6%, America — 13.3%, the Russian Federation — 13.7%, African countries — 6.7%. At the same time, the share of sugar beet production in global production increased in Asian countries (from 15.9% in 2010 up to 18.6% in 2020), in the Russian Federation (from 10.1 to 13.7%), in African countries (from 4.6 to 6.7%). A decrease in sugar beet production was noted in European countries — from 55.4% in 2010 to 47.6% in 2020, in American countries — from 14 to 13.3%. In the Russian Federation, sugar production per capita generally meets not only rational consumption standards, but also all criteria for food self-sufficiency. The excess of actual consumption over rational consumption in Russia is 62.5%. The lowest sugar beet production volumes are observed in countries such as Greece, Portugal, North Macedonia, Pakistan, Azerbaijan, Turkmenistan, Kazakhstan, Moldova, Kyrgyzstan, and some others.Results. The results of the study showed that in order to increase the economic indicators of sugar beet production, Russian commodity producers need to implement a policy of intensification of agricultural production along with updating the material and technical base using modern agricultural technologies and the development of their own breeding and genetic centers.

Relevance. The uniqueness of the practical application of accelerated and environmentally safe technology for the reclamation of oil–polluted lands, which uses local mineral raw materials, a consortium of autochthonous hydrocarbon-oxidizing bacteria with multifunctional positive properties, effective phytomeliorants, is theoretically substantiated. Hydrocarbon pollution is eliminated directly at the spill site, and the rate ofreturn of disturbed soils to agricultural circulation is 3–4 times faster than traditional methods.Methods. Objects of research: mechanically activated bentopowder and nanobentonite, a consortium of hydrocarbon-oxidizing bacteria composed of three autochthonous strains, soil leached chernozem, spring wheat, Devonian oil. The concentration of oil pollution at the site was 6.4%. Bentopowder and nanobentonite were introduced in doses of 6.0 t/ha and 0.3 t/ha, respectively. Sampling was carried out with a sampler on the 0th, 15th, 30th, and 90th days.Results. The optimal doses of application of bento powder and nano bentonite to disturbed soil above the average pollution level (6.0 t/ha and 0.3 t/ha respectively) are recommended. After 15 days, the level of contamination is halved (to 51.1 g/kg and 40.8 g/kg with benton powder and nanobentonite respectively). Removal of the introduced mineral sorbent is not required, since it later becomes a source of mineral nutrition for autochthonous microorganisms-destructors and a soil improver. At the second innovative stage, a consortium formed from effective strains and adapted to specific conditions is used. The strains of the consortium fit into an ecological niche, adapt and begin to actively develop, utilizing oil and petroleum products. After a month, the level of contamination decreases to 19.2 g/kg and 9.2 g/kg with the addition of benton powder and nanobentonite respectively.

To increase the rating, publication activity and quality of published research of the journal «Agrarian Science», some indicators of the journal’s publication activity for 2022 are presented and an assessment of its change for the period 2022-2023 is given in this article. During this period, the composition of the editorial board has significantly expanded, which has a positive effect on the capabilities of the board and will expand the coverage of scientific fields published in the journal. In 2022 and 2023, 248 scientific articles were published in the journal “Agricultural Science” in four sections presented in the journal (“Agronomy”, “Animal Science and Veterinary”, “Agroengineering and Food Technologies”, “Economics”). The average number of authors in 2023 decreased by 0.5 — from 3.7 to 3.2. A decrease in this indicator positively indicates an increase in the “weigh” of each author in the article. Publication activity of foreign authors decreased from 12 to 6%. To return and increase the level of publication activity in foreign languages, measures will be taken to attract foreign scientists to publications. Over the period 2022–2022, the average number of citations in bibliographic lists of scientific articles increased from 17.0 to 17.2. We will increase this indicator to increase the scientific credibility of published studies.

Studies conducted in the Ryazan region have shown that both the presence of mineral nutrition and the nature of the predecessors in the crop rotation are extremely important for the soybean yield. The experiment was carried out on six-field crop rotations with two backgrounds of fertilizers — without fertilizers and with the application of (NPK)90. The soybean of the Georgiy variety, which is the fifth link in crop rotations, was used as an object of study. Barley, winter wheat, and various perennial grasses were present in each of the crop rotations. To replenish organic matter in the soil, the organic mass of plants in the form of crop residues after harvesting the main part of the crop and perennial grasses included in the crop rotation was crushed and incorporated into the soil. In each crop rotation at the time of soybean cultivation, soil fertility, yield and quality of soybean seed were studied in order to identify the best predecessors. It was revealed that the highest yield is achieved in a crop rotation with legume-grass grasses using (NPK)90 — the largest increase in relation to unfertilized options was 14%, 11% and 22.8%. Variants with fertilizers also demonstrate the best indicators of soybean seed quality in terms of protein and oil content, where crop rotations with legumes and grasses also reach the highest values. It was revealed that all fertilized variants with were characterized by better indicators of soil fertility compared to unfertilized ones. It is concluded that the presence of perennial sideral grasses has a positive effect on soil fertility and contributes to an increase in soybean yields.

Relevance. In recent years, this crop, which is cultivated in order to obtain oil and fiber, is gradually gaining its abundance, increasing the acreage. In many agro-industrial enterprises, hemp is being introduced into crop rotations, and plants for its processing are being built. This culture plays a huge national economic importance and finds its application in various industries. One of the main elements of cannabis cultivation technology is the use of highly productive varieties.Methodology. The laying of field experiments, related observations and records were carried out in accordance with existing methodological guidelines for conducting field and vegetation experiments with cannabis.Results. The most optimal variety for the conditions of the Southern forest-steppe zone of the Republic of Bashkortostan is the Nadezhda variety. This variety is superior to the others (Vera and Omegadar-1) in terms of quality and quantity. For example, from the 2021–2022 studies on biomorphometric indicators, it follows that Nadezhda achieved the best indicators for: plant height (194.50 cm and 194.33 cm), technical stem length (160.60 cm and 162.45 cm), inflorescence length (33.90 cm and 31.88 cm), stem diameter (0.8–0.9 cm), the number of internodes (8–9 pcs.), the average length of internodes (12.5 cm and 19.87 cm). The weight of 1000 seeds was 17.01 g and 18.10 g, oil content — 32.89% and 33.72%, yield — 0.88 t/ha and 1.71 t/ha. The greatest results in 2022 are associated with agrometeorological conditions.

The paper presents the results of a study of the influence of adaptogens of plant and animal nature on the productive qualities of Kazakh white-headed bulls and morphological changes in their liver. 40 6-month-old beef bulls were selected for the study, which were divided into 4 groups: I (control) group of bulls consumed only the basic diet, II — adaptogen leucea safflower, III — drone homogenate, IV — pantocrine at the rate of 0.01 ml per 1 kg of animal body weight. At 18 months, a control slaughter of 3 animals from each group was carried out. During the experiment, it was found that the mass of the paired carcass in the bulls of the experimental groups increased by 11.1–21.7 kg (4.25–8.31%, р ≤ 0.05), the slaughter weight by 11.7–23.0 kg (4.24–8.34%, р ≤ 0.05–0.01), the slaughter yield by 0.9–1.9%. The analysis of the morphological composition of the carcass indicates an increase in the specific weight of its edible part of the carcass: by weight of muscle tissue by 4.0–7.7 kg (4.66–8.97%, р ≤ 0.05–0.01), fat — by 0.7–1.4 kg (4.67–9.33%, р ≤ 0.05). There is a high degree of maturity and high nutritional value of the meat of bulls of the experimental groups. Histological studies of the liver of bull calves indicate that when using tincture from drones, the liver structure corresponds to the norm, while in the control group animals some signs of dystrophic changes without pronounced infiltrations and signs of stagnation were found.

Relevance. Determination of the parameters of stability and ecological plasticity of winter grain crops allows us to assess their adaptability and objectively characterize the practical value.Methods. The ecological plasticity and stability of winter grain crops (winter rye Secale cereale L., winter wheat Triticum aestivum L. and winter triticale Triticosecale) were assessed by grain yield. For the study, statistical data on yields in 2012–2021 in 54 municipal districts of the Republic of Bashkortostan were used. Yield stability was assessed by calculating the coefficient of variation (Cv) and mean square deviation of yield σd2), ecological plasticity — by calculating the yield regression coefficient (bi).Results. Winter grain crops on the territory of the Republic of Bashkortostan have different stability and ecological plasticity. Winter rye has relatively high stability (Cv 34.03% and σd2 4.28) and lower ecological plasticity (bi 0.77), low stability (Cv 42.35% and σd2 8.11) and high plasticity (bi 1.24) — winter wheat. Winter triticale occupies an intermediate position between winter rye and winter wheat. Identical reaction of winter grain crops to changes in soil and climatic conditions (place of cultivation) and agrometeorological conditions (year of cultivation). Winter wheat responds more negatively to deteriorating conditions and positively to improvements in soil-climatic (bi 1.17) and agrometeorological conditions (bi 1.21) than winter rye (0.78 and 0.79, respectively) and winter triticale (1.05 and 1.00, respectively).

Relevance. The task of modern feed production is to increase feed production, as well as improve their quality and energy saturation. A special place in solving this problem belongs to perennial legumes and grasses. At the same time, it is important to use precisely those crops and varieties that have the greatest biological potential.Methods. The objects of research were meadow clover (Pochinkovets variety and Topaz variety), timofeevka meadow (VIC 911 variety), ryegrass pasture (Karat variety and Express variety), for the realization of the biological potential of which solid mineral fertilizers (ammonium nitrate, double superphosphate, potassium chloride) are needed, as well as concentrated liquid complex fertilizers of the series “Ultramagus.”Results. Among the studied species of perennial grasses, meadow clover has the highest yield, so among the clover varieties, the Pochinkovets variety had the greatest potential. Varieties of meadow clover increased the collection of dry matter when applying solid phosphorus-potassium fertilizers and liquid complex fertilizer “Ultramag Combi”. The highest yield was obtained in variants with the combined use of root fertilization with solid fertilizers at the rate of P80K120 and foliar fertilization with liquid complex fertilizer “Ultramag Combi”. The yield of meadow clover, depending on the variety, ranged from 12.05 to 12.46 t/ha. Varieties of meadow clover Pochinkovets and Topaz in the conditions of the Smolensk region form a tall monodominant herbage capable of intensive regrowth during the season and yielding at least two full-fledged mowing under optimal cultivation conditions.

A special place among environmental factors affecting the body of animals is occupied by microorganisms— pathogens of infectious diseases. In this regard, the problem of circulation of associations of conditionally pathogenic microorganisms capable of causing a fairly wide range of pathologies in cattle in cattle is acute. The article provides a study of the microbial background of the vaginal-luminous contents selected in the acute purulent-catarrhal postpartum endomethry in cows. It was shown that 58 strains of opportunistic microorganisms of 13 species, classified into 6 genera, were isolated from 20 cows suffering from acute purulent catarrhal endometritis. The most frequently isolated cultures were St. aureus, E. coli (serotypes O4, O9 and O83), Str. pyogenes, Str. agalactiae, P. aeruginosa, Str. uberis and Str. faecalis. Moreover, the development of acute purulent-catarrhal endometritis in cows was more often caused by grampositive bacteria. Of the 58 isolated strains of microorganisms, 22 (37.9%) cultures caused the death of white mice when administered intraperitoneally. At the same time, gram-positive cocci were more likely to have pathogenic properties, namely representatives of the genera Streptococcus spp. (11 — 50.0%) and Staphylococcus spp. (6 — 27.3%) isolates, respectively. It was found that endometritis more often causes associations of opportunistic microorganisms, which included three joints in 14 (50.0%) cases, less often four joints in 7 (25.0%) cases. The isolated microorganisms were sensitive to only three antibacterial drugs: cefkin, cefepime and marbofloxacin.
