The features of the implementation of the production potential of cherry varieties in the conditions of southern horticulture are presented. The studies were carried out in the conditions of the Prikubanskaya fruit growing zone of the Krasnodar Krai in 2016–2022. The objects of research were 7 varieties of common cherry of various origins. The purpose of the research was to study the productive potential of cherry varieties and its main components, depending on the negatively changing environmental conditions. Methods. The research was carried out according to the “Program and methodology for the variety study of fruit, berry and nut crops” and “Program and methodology for the selection of fruit, berry and nut crops”. Statistical processing of the obtained data was carried out according to the method of B. A. Dospekhov. The studies were carried out using generally accepted and standard methods. The scientific novelty of the research lies in the identified patterns and features of the implementation of the production potential of cherry varieties in unstable environmental conditions and the impact of stress factors. According to the results of the research, early-fruiting varieties of cherries, Prizvanie and Ivanovna, which begin to bear fruit 2–3 years after planting, have been identified. It was found that the average fruit weight of the varieties varied from 2.98 to 6.38 g, depending on the biological characteristics of the variety and the conditions of the year. Large-fruited varieties with a fruit weight exceeding 5 g have been identified: Prizvanie (5.38 g), Timati (5.43 g), Ivanovna (6.38 g) and Khodosa (6.33 g). It was found that the yield also varied depending on stress factors and the degree of adaptability of varieties to them. Stably fruitful and high-yielding cherry varieties Ivanovna and Khodosa were identified, the average yield of which was 15.7 kg/tree. or 10.5 t/ha. It has been established that the dependence of the yield of cherry varieties of different origin on average annual temperatures is average (r = 0.65), on the sum of active temperatures – average (r = 0.37) and on the sum of precipitation – strong (r = 0.87). To create highly productive cherry plantations in the conditions of southern gardening, varieties Ivanovna and Khodosa are recommended.","PeriodicalId":125083,"journal":{"name":"Agrarian Bulletin of the","volume":"8 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139269868","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of the study is the analysis of ethno-economic problems and consequences of transformations of the mountain-taiga reindeer husbandry in Tofalaria. Research methods. To study the reindeer husbandry of the Tofs, an indigenous people of Siberia, a combination of ethno-economic and ecological-geographical methods, as well as elements of a systematic approach, were used, on the basis of which data on the state of reindeer husbandry as a component of the traditional economy were interpreted. Results. The role of transformational processes in the formation of the crisis of reindeer breeding, the decrease in the number of deer, and the change in the nature of land use has been established. Ethno-economic transformations have led to the loss of reindeer breeding skills and micro-areal development of reindeer pastures. It was revealed that the development of rural areas of Tofalaria requires a revision of the traditional ethno-economic complex. Taiga small-scale reindeer husbandry performs the transport function of providing hunting, it does not belong to profitable industries, there are no methods to calculate its effectiveness in objective terms. It is emphasized that the main guidelines for assessing reindeer breeding are the preservation of the deer population and the age and sex structure of the herd, as well as its symbolic significance for the ethnic culture of the Tofs. The request of the ethnosociety for the development of reindeer husbandry expresses both the needs of the traditional economy and the ethnocultural aspects of ethnicity. These conclusions contribute to expanding the understanding of the complex nature of traditional nature management systems and their sustainability. The practical significance of the results lies in the possibility of adjusting regional programs to support indigenous peoples, taking them into account. Scientific novelty. It has been established that in the crisis state of reindeer husbandry, the consequences of unfinished transformation processes and the contradictions caused by them in the natural and economic system of traditional nature management are still affecting. Inconsistency in management based on planned indicators and ignoring traditional experience laid the foundation for a negative scenario for the development of reindeer husbandry long before the post-Soviet transformations.","PeriodicalId":125083,"journal":{"name":"Agrarian Bulletin of the","volume":"23 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139269623","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, in grape nursery breeding, pre-plantng treatment of the seedlings (in own-root culture) and the basal part of the grafting (with grafted culture) is used to increase the yield of seedlings. There is very little data on the use of modern complex fertilizers during stratification and at nursery in the production of grafted planting material, which reflects the relevance of our research. The purpose of the study is. the exploring of the foliar application of the agrochemicals “Fertigrain Foliar Plus” on the intensity of the development of the leaf surfase of the Siberian grape variety. Methods. The methods of setting up the experience and analyzing the data obtained were used in the work, which are generally accepted in the practice of nursery breeding. Results. With additional application of “Fertigrain Foliar Plus”, a significant increase in biometric indicators was observed, namely: the total length from 84 cm (c) to 150.7–171.7 cm; shoot maturation from 25.7 % (c) to 45.4–48.0 %, shoot diameter from 5.6 mm (c) to 8.3–9.0 mm and leaf surface area with 645.1 cm2 (c) to 1995.8–3382.0 cm2. With an increase in the number of treatments, the ratio of the number of leaves by fractions changed in the direction of increasing their size, namely (< 5; 5.1–10; > 10 cm): in the control – 1 : 5 : 0; with double processing – 1 : 12 : 4; with triple treatment – 1 : 9 : 8; with quadruple treatment – 1 : 6 : 12. With an increase in the number of treatment from 2 to 4 times, there was no increase in the number of leaves, however, the average leaf size increased significantly from 8.5 to 10.5 cm. Scientific novelty. For the first time in the conditions of the Rostov region, a modern growth stimulator “Fertigrain Foliar Plus” was studied during the foliar treatment of grafted grape seedlings on nursery-garden.

Materials and methods were used in accordance with the assigned tasks. In the conditions of two farms specializing in the production of milk and located in the Belgorod and Pskov regions, studies were conducted, the object of which were cows of the Red-and-White and Holstein Black-and-White breeds at the age of 3–6 years with a gestational age of 240–250 days. As a result of experimental tests, it was revealed that in cows with moderate gestosis, in addition to traditional hypertension, proteinuria and edema, there is an increase in heart rate variability, tachycardia, hypersympathicotonia, neutrophilocytosis, lymphocytopenia and resorptive endotoxication. With a combination of gestosis and hepatosis, the appearance of new (integral) and strengthening of pathophysiological phenomena specific to each of these pathologies is observed. As a result, a symptom complex of severe pathology is formed with bradycardia, vagotonia, resorptive and metabolic endogenous intoxication, leukogram imbalance with a predominance of young cells, monocytopenia, eosinopenia, more pronounced neutrophilocytosis and lymphocytopenia, as well as a decrease in adaptive potential. The scientific novelty lies in the fact that, according to the data obtained, one of the directions of the progression of preeclampsia (gestosis) may be the development of comorbid pathology. At the same time, the deterioration of the animal's condition is a consequence of the aggravation of each of the associated pathologies and the formation of integral pathogenetic integration in the body. In this case, the choice of therapies should be focused on eliminating or alleviating the manifestation of gestosis and associated pathologies, as well as on leveling the pathogenetic mechanisms of comorbidity.","PeriodicalId":125083,"journal":{"name":"Agrarian Bulletin of the","volume":"10 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139268427","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Winter rye is grown in a variety of soil and climatic conditions, which indicates the evolutionary resistance to the action of abiotic stressors. Due to periodic spring-summer droughts in the conditions of the North-West region of the Russian Federation, the problem of drought tolerance in rye is of particular importance. The purpose of this study was to investigate 13 winter diploid rye collection varieties for drought tolerance and adaptability in the Northwestern region of the Russian Federation and to identify the most promising ones. Methods. Experiments were laid from 2018 to 2022 in a field plot located in the Northwestern region. To determine the drought tolerance of varieties we used indices: average productivity (AP), endurance index (TOL), yield stability index (YSI), drought tolerance index (DI), tolerance index (STI), geometric average productivity (GAP), drought tolerance index (DSI), agronomic drought tolerance (Adt), degree of yield reduction (X3). To calculate adaptability, the following indicators were used: d% - yield range in %, V% - coefficient of variation, Er – response effect, Ca – adaptability coefficient, Ci – intensity coefficient, d t/ha – yield range in t/ha. Results. The study years can be classified as drought years 2018, 2019, and 2022. The average yield in these years ranged from 3.6 t/ha for the variety Niva, to 4.99 t/ha for the variety Lota. Years 2020 and 2021 are favorable, with average yields ranging from 6.3 t/ha for the variety Niva, to 9.9 t/ha for the variety Ofeliya. The most drought-resistant varieties are Lota, Zubrovka, Talisman, Niva, Yaselʼda, the most adaptive are Zubrovka, Era, Ofeliya, Talisman, Yaselʼda. Of the listed methods of determining drought tolerance, we should pay attention to the Yield Stability Index (YSI) and Drought Tolerance Index (DI). To identify adaptability: the coefficient of adaptability (Ca) and the coefficient of intensity (Ci). Scientific novelty.

The use of medicinal plant extracts in animal production has recently increased due to the discovery of previously unreported side effects of antibiotics, including the cumulation of their toxic metabolites in food, as well as the increased occurrence of antibiotic resistance of microorganisms. Non-therapeutic use of antimicrobials is also associated with the spread of multiple drug resistance, including resistance to antimicrobials that have never been used in animal agriculture. It has long been known that components of plant substances have the ability to inhibit bacterial growth. It is becoming common practice to use plant essential oils to improve feed utilization by ruminants, and essential oils have long been known for their antimicrobial properties. The purpose of this work was to evaluate the metabolic effects of phytobiotic and joint use with antibiotic in controlling microbial load. According to the results obtained, it is clear that phytobiotic in addition to antimicrobial effects has other positive effects expressed in membrane stabilizing and antioxidant properties, but there are some negative effects associated with difficulty of digestion and absorption of lipid nutrients. At the same time, the combined use of phytobiotic and antibiotic showed itself as optimal, due to the good antimicrobial effect, while mitigating or eliminating the negative effects identified when using phytobiotic and enrofloxacin separately, namely, eliminating immunosuppressive and depressive effects, as well as the absence of manifestations of impaired digestion and absorption of fat-soluble nutrients.

The purpose and objectives of the study is to establish the levels of influence of chemistry and the degree of salinity on the onset of half (LD50) and full (LD99) death of seeds of alfalfa blue hybrid and yellow clover. To identify the degree of participation of each factor in the death of legume seeds using the correlation coefficient and determination. To conduct a comparative assessment of the salt resistance of the seeds of sweet clover and alfalfa. Methods. The main natural types of salinization characteristic of the forest-steppe zone of Western Siberia are selected as objects of study. The germination energy and germination of seeds were determined according to GOST 12038-84. Model variants of salt solutions for germination of seeds of sweet clover and alfalfa were created taking into account the proportions of the formation of the main types of salinization. The types of salinization are represented by sulfate-soda, sulfate-chloride (neutral), and gypsum chloride-sulfate salt. Scientific novelty. Drilling slurries stored in barns during the extraction of hydrocarbon raw materials correspond to similar salinization conditions. Artificial salinization of water-salt solutions with a given concentration made it possible to identify half (LD50) and complete death (LD99) of clover and alfalfa seeds at the appropriate level and chemistry of salinization. Comparison of neutral and sulfate-soda salinization showed that the presence of soda in the solution determines its toxicity by 86–87 %. The negative effect of neutral salinization appears to a greater extent due to an increase in osmotic pressure. The presence of gypsum in the nutrient saline solution reduced the toxicity to seeds of phytomeliorant crops by 1.9–2.5 times. Results. It has been established that under conditions of neutral and sulfate-soda salinization, plants experience an acute deficiency in calcium. The introduction of gypsum during chemical reclamation of salt pans and drilling slurries eliminates this deficiency. The establishment of indicators (LD50) allows you to adjust the seeding rate of phytomeliorants. The indicator (LD99) indicates the expediency of applying gypsum on salt pans and drilling slurries.","PeriodicalId":125083,"journal":{"name":"Agrarian Bulletin of the","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130490999","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose was to evaluate the PGP-attributes of Bacillus sp. and to reveal the morphophysiological features of rapeseed (Brassica napus L.) when inoculated with these rhizobacteria. Methods. The ability of Bacillus sp. strain TO15c isolated from the rhizosphere of Taraxacum officinale on Zack's nitrogen-free medium to produce indol-3-acetic acid (IAA) and phosphates was studied. In pot-scale experiments, the assessment of changes in the morphophysiological characteristics of rapeseed upon inoculation with rhizobacteria both in the absence and in the presence of nitrogen fertilizer was performed. At the end of 100-day vegetation, shoot length, total leaf area, fresh biomass, content of macronutrients and photosynthetic pigments were determined. Results. The ability of TO15c to produce IAA (up to 26 mg/L) and solubilize phosphate (up to 60 mg/L) has been proven. Soil inoculation with rhizobacteria in the presence of ammonium nitrate led to the increase in shoot length by 24 % and total leaf area by 16 %. The aboveground fresh biomass increased by 1.5 times, the underground by 2.5 times, and the content of macronutrients improved. The rise in the photosynthetic pigment content (1.5 times on average) was also noted when inoculated with TO15c. The maximum effect was achieved with the rhizobacteria and nitrogen fertilizer combined application. Scientific novelty. The effectiveness of Bacillus sp.
