Published: January 2025

Introducción: Esta investigación realiza un análisis comparativo de las percepciones respecto a la diversidad cultural de adolescentes procedentes de dos institutos públicos de Algeciras (Cádiz), uno con una presencia alta de alumnado procedente de Marruecos y el otro, por el contrario, con una presencia mínima de este alumnado. Metodología: Se realiza un cuestionario compuesto por cuatro bloques (percepciones sobre la diversidad cultural, consideraciones sobre la diversidad cultural, consideraciones sobre aspectos relacionados con los procesos de construcción de sus identidades y visión del futuro), a 275 adolescentes entre 14 y 18 años. Resultados: Existe una relación positiva entre vivencia en el centro educativo de la diversidad cultural y la percepción positiva de ésta. Discusión: El hecho de vivir en un entorno fronterizo multicultural no parece influir en la identidad cultural. El alumnado del centro segregado se siente menos identificado con la cultura española y menos europeo, siendo la religión una cuestión significativamente más importante en la construcción de sus identidades. Conclusiones: para avanzar en la construcción de una sociedad más intercultural debemos avanzar en el sentimiento de pertenencia del alumnado segregado y en la reducción de la percepción de interculturalidad conflictiva del alumnado del centro no segregado.

Authors: Belyaev A. A. , Shpatova T. V. , Nevolin S. V. , Gavrilets T. V.
Published: January 2025

The studies were conducted in three-year production experiments in the nursery of the agricultural production cooperative (APC) “Sady Baraby” in the Novosibirsk region to assess the effectiveness of the Bacillus bacteria strains in obtaining honeysuckle seedlings from lignified cuttings. The most effective stimulation of rooting of lignified honeysuckle cuttings was proven with pre-planting treatment with the strains B. amyloliquefaciens VKPM B-10642, B. licheniformis VKPM B-10562 and a mixture of 3 strains (experimental biopreparation Fitop 8.67) in concentrations of 1×105 CFU/ml to an absolute level of 36.9–40.5 %, 20.3–32.1 % higher than the control. All the studied bacterial strains reliably stimulated the increase in seedling biomass by 17.6–42.6% relative to the control, to a level of 11.7–14.2 g/plant. The most stable in the years of observation were the strain B. amyloliquefaciens VKPM B-10642 and a mixture of three strains, which can be stated to have the greatest growthstimulating effect on honeysuckle plants. An increase in the commercial quality of seedlings (I and II grades) was proven when using pre-planting treatment with the strains B. subtilis VKPM B-10641, B. licheniformis VKPM B-10562 and a mixture of three strains by 32.5–35.0 % relative to the control, to an absolute level of 70.7–72.0%. The highest yield of standard seedlings, on average over 3 years, was demonstrated with pre-planting treatment with the B. licheniformis strain VKPM B-10562 – 777.4 seedlings/variant, which should be recognized as the most promising strain for use in obtaining seedlings from lignified honeysuckle cuttings.
Importance of ecological factors in the regulation of colorado potato beetle populations using the predatory bug Podisus maculiventris
Authors: Shatalova E. I. , Andreeva I. V. , Khodakova A. V.
Published: January 2025

Since the middle of the last century, the practice of using the predatory bug Podisus maculiventris to protect nightshade crops from pests has been known in various regions of the world. In the conditions of the Siberian region, the use of Podisus to regulate the number of Colorado potato beetles has not found wide application to date, which is due to both the availability of the entomophage itself on the market of plant protection products and the need to develop methods and conditions for its use in the production of organic plant products. The paper presents information on the influence of environmental factors on the dynamics of the Colorado potato beetle population, the survival rate and the effectiveness of its entomophage on the colored potato variety Rosemaria. During the years of research, the number of phytophage generations developing during the growing season depended on the temperature factor. In 2023, a high number of the second generation of the Colorado potato beetle was noted, due to the warmer conditions of this growing season, while in 2022, egg-laying and second-generation larvae were single. The influence of local weather conditions on the survival of podisus individuals released into open ground and, as a consequence, on its regulatory activity was noted. Differences in the effectiveness of the entomophage depending on the method of its release were revealed. With uniform dispersal of P. maculiventris nymphs over plants, a decrease in leaf damage by the Colorado potato beetle and an increase in its biological effectiveness were observed compared to the option of releasing podisus at one point. The maximum effectiveness of podisus was noted on the 7th day after its repeated release and was 87.8 and 90.9 % in 2023 and 2022. respectively, in the variant with uniform distribution of the entomophage among plants, while when released at the control point, the biological efficiency was at the level of 63.8 and 64.4 %. The potato yield in the variants using the predatory bug was 1.3-1.5 times higher compared to the control and varied from 124.3±6.6 to 149.9±6.5 c/ha depending on the year of research and the method of release of the entomophage.

Published: January 2025

The aim of the study was to assess the well-being of sows at a farrowing site with a fixed content in the conditions of industrial pork production technology. The object of the study was suckling sows contained in BDSwing machines on lattice floors. The Welfare Quality® protocol was used for the assessment, modified in accordance with local production features. The well-being of the sows was assessed on the first day after farrowing and again on the 15th day of the suckling period. When processing the data, the total welfare score of the sows was calculated. The fatness of the sows was determined by the thickness of the fat above the last rib on the 30th day of pregnancy and at weaning at 28 days. The statistical analysis was performed using the statistical programming environment R. The reliability of differences between groups of animals in fatness on the 30th day of pregnancy and at weaning was assessed by the Kraskel-Wallis method. Pairwise comparisons were carried out with the Hill correction. In the group of well–off sows, the total score was 0.62 points, while for the conditionally well-off, this parameter was already 2.51 points and the disadvantaged – 4.9 points. The re-evaluation was carried out on the 15th day after farrowing by the same researcher. With minor changes in the total assessment of animals (0.59, 2.49 and 5.12 points, respectively), there is an increase in the total assessment in the group of disadvantaged sows, as well as the movement of animals from one group to another in the direction of aggravation of the condition. Significant differences in fatness between well-off and conditionally well-off and dysfunctional sows on the 30th day of pregnancy were determined. At the same time, although healthy sows differed in the smallest fat thickness, during pregnancy and suckling period, in this group the least loss of fatness to weaning was noted (-0.3 mm).

Authors: Biryulya I. K. , Zaiko O. A.
Published: January 2025

The genesis of internal organ systems is determined by a spectrum of various factors and characterizes the growth rate of animals, their constitution, resistance to diseases and the ability of animals to adapt to environmental conditions. An assessment of the absolute weight of the lungs, brain and heart of Landrace pigs of Irish selection was carried out. At the early stages of the technological cycle, a representative group of pigs was formed, taking into account their origin, sex, age, and live weight. The total number of animals was 12. The fattening of the animals took place in a large pig-breeding farm in the Altai Territory, where standard living conditions were provided according to the standards of meat fattening of animals. Vaccination of animals was carried out in accordance with the preventive plan, and systematic veterinary control was provided. At the end of the technological cycle, when the live weight reached 100 kg, slaughter was carried out on the basis of the current technological instructions. The absolute mass of organs without surrounding structures was determined by weighing on scales with a high accuracy class. The obtained data were evaluated using Microsoft Office Excel and the R programming language in the data analysis environment RStudio version 2022.07.2+576 (RStudio, PBC). Visual assessment showed the absence of pathoanatomic changes in organs. In all cases, based on the ShapiroWilk test, a normal distribution was established. In pigs, the median absolute lung weight was 447.8 g, brain – 81.6 g, for the heart – 33.8 g; 95% confidence interval for the lungs – 245,56 525,85 g, for the brain 45,33–98,42 g, for the heart – 190,21–404,49 g. The article provides indicators of variability of the trait in question. The interbreed differentiation of pigs by lung and heart weight has been established.
Current pathogenicity factors of viral and bacterial pathogens of young cattle
Authors: Bryadnov V. S. , SHkil N. N.
Published: January 2025

Infectious pathologies of animals remain the main problem on the path of high productivity, preservation and, as a result, productive longevity of animals and ultimately determines the profitability of agricultural industrial production of animal products. The possibility of developing pathologies is caused by specific substances of predominantly organic origin (proteins, enzymes, toxins, glycopeptides, etc.), which cause a set of highly specific pathogenic properties of microorganisms. In this connection, there is a growing interest and need to study the pathogenic properties of viruses and bacteria, which cause a number of mechanisms that ensure the neutralization of protective immune mechanisms of animals (adhesive, anti-complementary, anti-lactoferin, antihemoglobin, anti-lysozyme activity, biofilm formation, antibiotic resistance, etc.). The study and development of effective methods to counteract these pathogenicity factors is possible only taking into account the study and search for the practical application of specific substances in the form of vaccines and drugs. Numerous studies of infectious agents causing pathology of the gastrointestinal tract with diarrhea syndrome in calves, according to statistics, distinguish the most common bovine rotavirus, bovine coronavirus, bovine viral diarrhea virus, bovine calicivirus and bovine torovirus, as well as bacteria Salmonella spp., E. coli, C. perfringens and C. parvum. The data from the review of the pathogenicity factors of bacteria and viruses show their diversity, which causes various forms of the course and manifestations of infectious pathologies. Monitoring and further study of the antigenic profile of infectious pathogens allows timely development of relevant diagnostic methods for their identification. The study of protein antigenic proteins makes it possible to develop means for the treatment and prevention of infectious animal diseases.

Authors: Zyryanova A. A. , Klescheva A. A. , Sevostyanov M. Y.
Published: January 2025

The economically important productive traits of cattle that contribute to the development of the dairy industry are considered to be abundant milk yield, protein and fat content in milk. In recent years, breeders have focused their attention on cattle breeding programmes based on molecular genetic research methods. The potential of animal productivity largely depends on genetic variants of marker genes present in the genotype of an individual. The genes of kappa-casein and somatotropin are considered to be promising DNA markers, as they are responsible for qualitative and quantitative traits of cattle productivity. In this work we studied milk productivity of 84 cows of Simmental breed from the breeding plant in the Urals by kappa-casein and somatotropin genes, as well as by complex genes. On the gene kappa-casein on milk yield in advantage are individuals with genotypes CSN3AB 6937,6 kg. The higher content of protein in milk, milk fat and protein yield, as well as the sum of nutrients were recorded in cows with CSN3BB genotypes 3.40%, 282.5 kg, 234.2 kg and 516.7 kg, respectively. In terms of somatotropin gene, cows with GHVV genotypes had the most abundant milk production 7160.0 kg. In terms of protein-milk yield, coevals with GHLL genotypes are more productive 3.4 %. The sum of nutrients, milk fat and protein yield is more established in milk of cows with GHVV genotypes 522.7 kg, 293.6 kg and 229.1 kg, respectively. All nine possible variants of complex genotypes for kappa-casein and somatotropin genes occur in this Simmental herd: AA/LV 26 cows; AA/LL 14; AA/VV 12; AB/LL 13; AB/LV 10; AB/VV 2; BB/LL 4; BB/ VV 2; BB/LV 1. Data processing on the effect of complex genotypes on milk productivity included a number of 10 cows or more. Higher milk yield, milk protein content, milk fat and protein yield, and nutrient sum were found in AB/LL complex genotypes: 6756.0 kg, 3.4 %, 277.0 kg and 229.7 kg, 506.7 kg, respectively. Significant differences were found between cow groups in the content of mass fraction of protein.

The paper presents the results of studying the polymorphism of microsattellite loci of Yaroslavl cattle in breeding herds of the Yaroslavl region. 115 alleles with different frequency of occurrence were identified for 15 microsatellite DNA loci. From 5 to 11 alleles were identified in each of the studied loci. The average number of alleles per locus was 6.41, the number of effective alleles was 3.58. The highest incidence (0.75) in the entire population was found in locus SPS115 with allele 248, its distribution ranged from 0.72 to 0.83 across farms. For the SPS115 locus, the rare alleles are 252, 254 and 256. 6 alleles were identified at the BM1818 locus. Allele 266 has the highest frequency of occurrence in all the studied herds, and alleles 262, 264 and 270 are present in sufficient numbers. The allele 182 has the highest frequency of occurrence in herds at the BM1824 locus (from 0.46 to 0.64), with an average of 0.51 in the sample. Rare alleles have been identified, which are present only in individual herds with a frequency of occurrence from 0.01 to 0.02. The average number of observed heterozygosity was 0.71, and the expected one was 0.60% less than the observed one. The study found that the first hard the heifers had the highest yield (6871 kg, p < 0.001), rare alleles were identified in this herd – 179 at the CSSM66 locus and 268 at the BM1818 locus. The largest number of alleles, which are not present in other herds, was revealed in the breeding herd III. The higher fat content was obtained from the first heifers of this herd – 4.36% and the higher protein content – 3.45%.The fixation index in all the studied herds was negative (-0.019), which indicates an excess of heterozygotes. The obtained data will allow controlling the level of homozygosity in herds, and taking into account the allelic polymorphism of the breeding stock when fixing bulls of producers to obtain breeding offspring and in custom mating.

Published: January 2025

Experimental work was carried out in 2021–2023. in order to study the influence of sowing timing on the productivity of angustifolia lupine in the conditions of the Krasnoyarsk forest-steppe. The objectives of the research included determining the effect of the timing of sowing angustifolia lupine on seed germination and the safety of plants for harvesting; studying the influence of crop sowing timing on grain yield; assessment of the contribution of factors to the formation of lupine grain yield. The experimental design included three dates for sowing lupine: 1st date (early) – May 5; 2nd term (middle) – May 15; 3rd deadline (late) – May 25. The objects of research were narrow-leaved lupine varieties bred by the All-Russian Research Institute of Lupine Vityaz and Belozerny 110. The hydrothermal regime of growing seasons differed according to the years of observation: in June 2021, as well as in July and August 2022, plants experienced a lack of heat; in 2021 and 2023 there will be a moisture deficit. The research results showed that the field germination of seeds varied according to the experimental variants and depended on the moisture supply of the soil at the sowing depth, which developed under specific growing season conditions. The best seed germination of the Vityaz variety was noted at early sowing dates in 2021 and 2022, and at late sowing dates in 2023; for the Belozerny variety 110 at the average sowing time in 2021, at the late sowing time in 2022 and in 2023. The safety of plants for harvesting decreased from the first sowing period to the third for both the Vityaz variety and the Belozerny 110 variety. Early sowing of lupine provides the highest grain yield of the crop. On average over the years of the experiment, the yield of the Vityaz variety during early sowing was 12.4 c/ha; during the average sowing period, the crop productivity was 12.9% lower, and at the late sowing period it was 50.8 % lower. A similar trend is observed in the variety Belozerny 110: in the 1st sowing period the average yield was 12.2 c/ha, in the 2nd period it was 11.5 % less, in the 3rd period it was 44.3% less. The formation of lupine productivity is significantly dependent on both the timing of sowing (contribution of the factor – 34.7–47.4 %) and on the growing season conditions (contribution of the factor – 39.6–51.9 %).

The research was carried out on the basis of the agricultural production complex “Dur-Dur” (Russian North Ossetia – Alania) on laying hens of the “KOBB-500” cross, of which, at the age of 155 days, when transferred to the parent stock workshop, according to the principle of analogous groups, 4 groups of 100 heads each were formed. The duration of this experiment on laying hens was 10 months. It was found that joint feeding of antioxidants vitamin C at the rate of 500,0 g/t and Erytox at the rate of 125,0 g/t of mixed feed to laying hens of the 4-test group contributed to the improvement of hematopoietic function. Due to the synergism of the action of the tested antioxidants, laying hens of the 4-experimental group were distinguished by better indicators of carbohydrate, protein, lipid and mineral metabolism, which, compared to the control, manifested itself in a significant (P > 0,95) increase in blood serum glucose by 0,53 mmol/l, total protein – by 4,48 g/l, alanine aminotransferase activity – by 5,00 units/l and aspartate aminotransferase – by 5,97 units/l, calcium concentration – by 0,73 mmol/l) and phosphorus – by 0,69 mmol/l with a simultaneous decrease in total lipids – by 0,59 mmol/l (P > 0,95) and cholesterol – by 0,93 mmol/l (P > 0,95). In addition, in laying hens of the 4th experimental group, relative to the control, the body’s antioxidant defense processes were optimized due to an increase in the activity of glutathione peroxidase in the blood by 7,31 % (P > 0,95) and glutathione reductase by 19,96 % (P > 0,95).

Phospholipids make up the structure of cell membranes and organelles, influencing the activation of cellular enzymes. They are involved in the intercellular transport of fats, fatty acids, cholesterol and other substances in blood lipoproteins. These compounds, being natural metabolites, contribute to more efficient use of fat and prevent its excessive accumulation in tissues. Phospholipids have emulsifying properties, of particular interest are lecithins, which are phosphatides. Lecithin-based supplements in poultry feeding improve growth, reduce the risk of perosis, have a beneficial effect on skeletal formation and accumulation of vitamin A in the liver (lecithin has a synergistic effect). They also protect farm poultry from the development of liver obesity syndrome. The aim of the research was to study the effect of the phospholipid-fatty acid complex on the main zootechnical indicators in the cultivation of broiler chickens. Partial replacement of sunflower oil with fatty acids at various age periods by 0.69–1.48 % and phospholipids by 0.84–1.8 % (according to the experimental scheme) contributes to an increase in the safety of broiler chickens by 2.5 %. The inclusion of a phospholipid-fatty acid complex in broiler diets is advisable, which is confirmed by an increase in live weight by 1.95–7.42%; a decrease in conversion by 0.01–0.02 kg/ kg; preservation of safety indicators at the level of 97.5–100 %; an increase in income from the sale of chickens by 4.57–7.42 %; making a profit of 52.60–104.98 % more in comparison with the control; increasing the level of profitability by 1.01–2.19 %.

L-carnitine is an essential amino acid (a building block of protein) required for fat and energy metabolism, and a nutrient that promotes normal functioning of the heart and skeletal muscles. Experimental and clinical results indicate the feasibility of using L-carnitine preparations in veterinary practice. There is no registered form of Levocarnitine injectables for use in animals of different species in the Russian Federation. The aim of our study was to establish the effect of injectable L-carnitine on the internal organs of laboratory animals. When studying subchronic toxicity, the animals were divided into 3 groups of 10 animals each. The drug was administered intramuscularly daily for 42 days, to the first group at a dose of 0.08 mg / kg, to the second group 0.04 mg / kg, the third group was a control. Slaughter of 50% of the rats for the purpose of collecting biological material was carried out the next day after the end of the drug administration (43rd day of the experiment), in the remaining animals 10 days after the end of the injection (53rd day). Pathological examination of the corpses of unproductive animals was carried out in accordance with GOST R 57547-2017. The Mann-Whitney statistical criterion was used to process the data. During the pathological examination (autopsy) of the corpses of laboratory animals on days 43 and 53 of the experiment, the pathological picture did not change, but isolated changes were found in the heart and liver of rats in the experimental groups. The absence of statistically significant changes in the weight coefficients may indicate the stability of this indicator when using levocarnitine in the studied dosages and administration times.

Russian and foreign scientists continue to systematize knowledge about the accumulation of macroand microelements in the body of animals, as their study remains an urgent topic for many studies. Questions about the hereditary determination of the level of macroand microelements in animal organs and tissues are also being studied. Currently, articles by Russian and foreign authors contain separate, disparate information about the macroand microelement status of farm animals and fish of different species. Our article describes data on the phosphorus content in the liver of offspring obtained from producing bulls of the Holstein breed. The research was conducted in Kuzbass. The studied animals were in the same conditions of maintenance and feeding. The groups were formed according to the principle of analogues. The same feeding and maintenance conditions were created for the experimental animals. In the animal breeding area, the content of macroand microelements in soil, water and feed was determined, the level of heavy metals was within acceptable concentrations. The phosphorus content in the liver was determined by atomic emission spectrometry on the ICP AES IRIS device. The phosphorus level in the offspring of the sons of different Holstein bulls was in the range of 2964–3417 mg/kg. In the liver of the descendants of some bulls, the phosphorus content was 1.15 times higher than in others. The index of the strength of the influence (RW) of fathers on the phosphorus content in the liver of sons was 0,49 (p < 0.05). This indicates the influence of the genotype of fathers on the phosphorus content in the liver of descendants. The level of phenotypic variability of phosphorus concentration in the liver of offspring of different bulls was in the range of 5.6–11.6 %. The obtained average values of phosphorus levels can be taken as the physiological norm for animals of the Holstein breed in Western Siberia. The study of the level of phosphorus and other elements in organs and tissues expands the understanding of the chemical status of animals and is a characteristic of the interior.
The possibility of using a natural drug as an antistressant to herbicides in soybean crops

The results of research on the use of a drug of natural origin as an antistressant to herbicides are presented. Soybean plants, like other crops, are exposed to stress not only from abiotic (spring-summer and summer droughts), but also from anthropogenic factors (pesticide treatments). Experiments were conducted in the northern forest-steppe of the Novosibirsk region in 2020-2021 on leached chernozem. The objects of the study were the humic preparation Cytohumate and soy varieties SibNIIK-315 and Zolotaya. It has been shown that the Cytohumate brown coal antistressant at a rate of 0.4 l/ha improves the physiological state of soybean plants, provides rapid biomass growth and increases crop yield. The humic preparation contributed to the timely passage of the phenological phases of soybean development. Due to the reduction of the stress effect against the background of Cytohumate in 2020, the phenological phases occurred 2–3 days earlier than in the control. In the dry conditions of July 2021, an acceleration of the budding and flowering phases was noted. Against the background of a natural antistress agent in 2020, an increase in soybean height was statistically proven. The use of the humic preparation had a stimulating effect on the biomass of the cultivated plant. This was most noticeable in the wetter 2020, when the biomass in the experimental variant was significantly higher than the control by 16.8 %. In 2021, in the case of using Cytohumate, only a tendency to increase biomass was observed and the differences from the control were 7 %. The yield increase when applying Cytohumate as an antistress agent to herbicides amounted to 0.4–0.5 t / ha of grain.
The effect of the load of bushes with shoots on the stress resistance of grapes of the varieties Vladimir, Dmitry, Kurchansky

Due to the currently observed global and local climate changes, there is an imbalance in the biological cycles of plants, a change in their resistance to biotic and abiotic stressors. The level of realization of the potential of economic productivity of grape varieties in the Krasnodar Territory is low and amounts to 60%. At the heart of its increase is the optimization of the placement of grape plantations, taking into account varietal characteristics and variety-oriented, zone-oriented technologies of grape cultivation. Varietal agrotechnology, which provides for the establishment of an optimal load of grape bushes with shoots, plays an important role in regulating the growth of the grape bush and its individual parts, the formation of plant resistance to stressors and the quality of viticulture products. Due to the more frequent manifestation of stressful weather conditions during the growing season of grapes, namely, insufficient soil moisture in combination with high temperature and low humidity, an urgent area of research is the study of stress resistance indicators under different loads of bushes with shoots. The purpose of the research is to study the effect of the load of bushes with shoots on the stress resistance of grape varieties of domestic selection Vladimir, Dmitry, Kurchansky. Indicators characterizing the stress resistance of plants, such as electrolyte yield, hydration, water deficiency and loss of water by leaves (water retention capacity), have been studied. A variety-specific reaction of grape plants to changes in the load of bushes with shoots under stressful conditions (insufficient precipitation and high air temperature) has been established. Increasing the load in Dmitry and Kurchansky grape varieties improves stress resistance indicators, such as tissue hydration, water deficiency and water retention capacity. The Vladimir variety had the best performance with a minimum and average load of bushes with shoots.

In crop breeding, clustering of samples at a minimum of the Euclidean distance causes the combination of a set of features (morphological, biochemical, phenological, economic, and others) into clusters according to their objective similarity. Recently, breeders have widely used this method to evaluate the source material and form collections for purposeful breeding. The aim of the research was to cluster the working collection of sugar sorghum samples according to a set of characteristics, followed by the selection of the most valuable genotypes for targeted further breeding of hybrids with a high yield of sugars per unit area. In the presented work, 47 genotypes of sugar sorghum were used as research objects, which were grown in the experimental field of the Federal State Budgetary Research Institution Russian Research and Design-Technological Institute of Sorghum and Corn in the period from 2021 to 2023. The growing conditions of the crop can be characterized as arid: the hydrothermal coefficient varied from 0.62 to 0.75. The collection in question included genotypes with variability of the studied traits from 6.9 to 47.4 %. At the 42nd iteration step, the samples were grouped into 6 clusters, significantly differing in all characteristics, except for plant height. The first cluster consists of 8 varietes, the second – 28, the third – 4, the fourth – 4, the fifth – 1, the sixth – 2. The most promising were 34 samples from 2, 3 and 6 clusters, characterized by tallness (188.9-198.8 cm), productivity (seeds – 2.50-2.57 t/ha, aboveground biomass – 20.09-31.53 t/ha), high sugar content in the juice of the stem (16.4-17.0 %) and a powerful leaf apparatus (the area of the largest leaf is 207.9-312.8 cm2, flag – 65.2-156.8 cm2). The involvement of selected samples in the breeding program will contribute to the creation of hybrids of the first generation of sorghum with a high yield of sugars per hectare of crops.

Field peas (Pisum sativum L.) are the most important leguminous crop for the northern regions of Russia, used for green cattle feed. The experience in the variety study of field peas was laid on the basis of N. Laverov Federal Center for Integrated Arctic Research of the Ural Branch of the Russian Academy of Sciences in 2021-2023, where the productivity and nutritional value of six new varieties of field peas of various origins were evaluated: Tyumenets, Frigate, Boar, Veles, Tan, Varys. The research was carried out according to the methodological guidelines “Methodology of the State Commission for Variety testing of agricultural crops”. Peas were grown in a single-species crop. The aim of the work was to evaluate varieties of seeded peas of various origins in terms of feed productivity and nutritional value and to identify the most adaptive to the conditions of the Arkhangelsk region. The growing season for the green mass varied from 36 to 41 days, the yield of the green mass from 17.9 to 35.5 t/ha. As a result of the conducted experience, precocious productive varieties of field peas with high biochemical parameters were identified – Veles, Wild Boar, Frigate, Tan. According to the main economically valuable characteristics, the Tan variety stood out. It has been established that it is effective to grow new varieties of field peas for green fodder in extreme climatic conditions.
