Abstract
A comparative study of the biological characteristics of the heifers Bredy meat type of two populations located in Russia and Kazakhstan was carried out to determine the state of genes associated with the meat quality in the genotypeCAPN1, GDF5, TG5, BGL. In genotyping, we used the real-time PCR method using oligonucleotide primers (Gen Bank), for each primer individually in the corresponding sequences. Studies for improve breeding by innovative methods revealed the frequencies of genotypes and alleles for marker genes CAPN1, TG5, BGL and GDF5, which are related to meat quality indicators, a certain displacement in the genotypes of the compared populations of the Bredy meat type of Kazakhstan and Russia according to the CAPN1 gene (χ2 = 8.52) and the TG5 gene (χ2 = 4.73). The genotyping result of animals from LLC “Breeding plant Bredy” were analyzed from the point of view of attributing carriers of different genotypes to the offspring of bulls-producers Fakir, Kust and Chizhik, in order to determine the producer giving offspring with predictably high nutritional and biotechnological properties of beef. A comparison of the carriers of the identified genotypes of the studied genes by the characteristics used in the evaluation of young animals by their own productivity did not give significant results, however, showed trends by which scientific research can be directed. An assessment of the bulls-producers of the successors of the different line of meat simmentals on the quality of heifers – daughters showed that the largest comprehensive index was set for the bull-producer Bush 39046 – 102.7, which was recognized as an improver. The assignment of all, without exception, heifers of different groups, evaluated bulls-producers, to the highest class elite-record, indicates the value of all the studied genotypes.

Authors: Yausheva E V 
Published: January 2021

Abstract
The paperis aimed at studying the increasing efficiency in the poultry meat production when using iron and copper nanoparticles in nutrition. A maximum increase in the gain in live weight of chickens by 9-12 % in comparison with the control group in the first week after the injection of nanoparticles is observed. An increase in values of a number of blood parameters (hemoglobin, total protein, white blood cells) is noted. Copper nanoparticles increase the body’s immune response on the first dayof experiment by several orders in comparison with both control and iron nanoparticles. The analysis of mineral exchange data showed a decrease in a number of toxic (As, Pb, Al, Cd) elements and an increase in the level of a number of essential (Mg, Co, Fe, Cu, Na, F) elements in broiler tissues after exposure to copper nanoforms and iron nanoforms. The analysis shows more effective influence on the metabolic processes of chickens and require further detailed study of the processes of their transformation in the broiler body. The obtained result shows the possibility of using these forms in the industrial production of animal feed.

Published: January 2021

Abstract
The study concerns the influence of Valopro and Ruprocol fodder additives on the change of the growth energy and formation of meat productivity of Kalmyk bull calves during their nursery from 9 to 18 months of age. The addition of Valopro at a rate of 20 grams and Ruprocol at a rate of 50 grams per head per day to the basic diet during 273 days contributed to a daily gain of 1580–1560 g, which is 200–250 g higher than the control animals. The bull calves of the experimental group used 2.0 % more daily time for eating fodders and 1.6 % less for their chewing, besides, they had less rest standing and moved in a pen, and during the whole experimental period gave 426 kg of absolute gain, or 76 kg more than the herdmates of the control group. The experienced bull calves showed higher resistance to upper respiratory tract diseases, eye diseases, laminitis and hepatosis. During the control slaughter, the body weight and heavy carcasses of bull calves of both groups met the requirements of the current GOST category Super. The hot carcass weight of the bull calves of the experimental group averaged a little more than 362 kg, i.e. 62 kg more than the control group (P≤0.01). Each bull calf gave 11488 rubles profit, which is almost 4.5 thousand rubles more than the herdmates of the control group. Therefore, the latter have almost 5 % lower profitability.

Authors: Berdennikov E A , Tarasov E N 
Published: January 2021

Abstract
The basis of automotive equipment used in agricultural enterprises are tractors, cars and self-propelled combines. They are equipped with internal combustion engines, the design feature of which is the presence of replaceable, so-called “wet” cylinder liners. Nevertheless, engines with an integral cylinder block design have also found applications at the enterprises of the agriculture-industrial complex. It is important to develop a mathematical model that allows calculating the force of pressing the sleeve into the block, while designing the technological process of cylinder block linings for such engines. Regarding this, the Department of energy resources and technical services in Vologda State Dairy Academy Named after N. V. Vereshchagin conducted an experiment, which is based on force measurement for press fitting the sleeve into the engine block and comparison of the measurement results with the results of theoretical calculations according to Lamet formulas. Relying on the results of the experiment, the method (Lamet formula) is deemed to be applicable to determine the force of pressing the sleeve into the engine cylinder block with optimal tension, which is valid for thick-walled cylinders.

Authors: Frizen Yu V , Nekrasova E V , Nozhenko T V , Kozhevina M N 
Published: January 2021

Abstract
The false flax is a highly effective crop used to oust weeds. However, its crops sometimes must be treated with herbicides. There are no herbicides recommended to treat this plant in the range of chemical solutions available. This fact calls for the study aimed at finding herbicides that can be used to treat the false flax. Experiments carried out on the field of the scientific-experimental farm of Omsk State Agrarian University were aimed at determining the impact of five herbicides on the weed infestation and the yield of the false flax. Samples receiving no treatment and those undergoing manual weeding were used for control purposes. No treatment and Lontrel-treated samples were heavily infested (with the weed weight proportion of 43.0% and 20.3% respectively). The slight infestation was observed in samples with manual weeding (2.2%) and Lornet-treated (9.2%) samples. The medium infestation was observed in samples treated with Reper, Khiler, and Miura (10.7%, 10.2%, and 18.8% respectively). The highest yield was observed in the manual weeding sample (1.83 t/ha), the yield of the Khiler sample was a little bit lower (1.52 t/ha), and the lowest yield was found in the Miura sample (0.55 t/ha).

Published: January 2021

Abstract
The aim of the research was to establish a functional dependence of the quality of the feed mixture on the degree of filling the volume of the modernized drum mixer and the proportion of the controlled component with the identification of the working area of the investigated working body. The methodology for studying the quality of the mixture of a drum mixer provided for the experimental establishment of the function of changing the coefficient of variation of the concentrated feed mixture with a three-level combination of the degree of filling of the tank and the proportion of the controlled component. The conducted studies based on the developed methodology allowed to identify an adequate functional dependence of the influence of the proportion of the controlled component and the degree of filling of the mixer drum. The results obtained indicate that an increase in the proportion of the controlled component improves the quality of the mixture with the nature of the hyperbolic dependence. Technological requirements for the quality of the mixture are observed when the proportion of the controlled component is at least 17%. This imposes a partial restriction on the use of the mixer for the preparation of dry concentrated mixtures based on protein-vitamin supplements and crushed feed grain. The effect of the degree of filling on the quality of the mixture is more complex and corresponds to a parabolic dependence. With the degree of filling 0.28-0.32 of the volume of the drum, the best indicators of the quality of the mixture are observed. The optimum mixing is observed with a batch mass of 45-51 kg at a density of 620 kg/m3.

Abstract
The acceleration of the process of import substitution is becoming a crucial issue in contemporary Russia and priority areas of such process are identified in plant breeding and seed production. A hot topic in the breeding of beans consists in creation of highly productive varieties with stable productivity. Field experiments were conducted at the Omsk State Agrarian University in 2014-2018 in order to evaluate the adaptation properties of prominent varieties of dry beans in terms of yielding capacity. All sorts were grown using the methods of organic farming, without application of pesticides and fertilizers, which allowed for an accurate evaluation of their biological productivity. The parameters of stability and plasticity of the genotypes under study were calculated following the methods of regression analysis (Eberhart, Russell, 1966). The associated trait of the studied feature in dry beans is mainly influenced by “environmental factors” (75%), to a lesser degree by the correlation “genotype x environment” (17%) and by “genotype” (7%). Based on the evaluation of the adaptation capacity and stability of the genotypes of common beans, samples with a high responsiveness to the improvement of cultivation conditions (Omichka, Luker’ya, Sizaya, Shokoladnitsa, Olivkovaya and Omskaya yubileinaya) and with a high genotype stability (Biichanka, Sibakovskaya-100, Rubin, Nerussa, Petukh) have been identified.

Published: January 2021

Abstract
The article presents the five-year results of the studying the adaptation of varieties, and hybrids of Jerusalem artichoke in the forest-steppe of the Omsk region. The analysis of biometric indicators and crop yield structure is presented. The dynamics of the accumulation of herbage, as well as the periods of the passage of phenological phases are shown. The chemical composition of plants is determined. The studies show that many hybrids and varieties in Western Siberia do not go through the flowering phase, but at the same time form a full-fledged tuber crop. At the same time, the high yield of the aerial mass of Jerusalem artichoke does not always ensure a high yield of tubers. On average, for five years of research, the French D-5 hybrid, Canadian sample and variety samples’ No. 1 and No. 9 we distinguished in terms of herbage productivity. This indicator was 49.4-58.9 t / ha. In terms of tuber productivity, the best varieties were No. 9 and No. 12, as well as the Sireniki-1 variety (29.1-30.2 t / ha). The distinguished varieties and hybrids of Jerusalem artichoke are recommended for the introduction into production in order to improve the forage base of agricultural enterprises. The research on the selection of varieties and hybrids in order to obtain high-tech tubers (large and aligned) for processing in the food industry will be continued.

Abstract
Table carrots is one of the most popular and widespread vegetable crops. Systems for the production of varietal root seeds using advanced technology are being developed for cultivation of high-yielding seeds in different natural and climatic zones. In general, the following indicators for certain technological aspects can be recommended under the studied system of production of high-yielding garden carrots seeds for the West Siberian region: table carrots of the Shantane variety are the most suitable for complex mechanization in the conditions of the Siberian region and have excellent taste qualities; the preparations Tsirkon and Epin extra effectively stimulate seeds germination. Laboratory germination ranges from 65 (in the control variety) to 86.6% (in the variety treated with Tsirkon); treatment of root crops with 40% arasan preparation allows for a significant increase in the seed yield from 1.6 in the control variety to 2.6 t/ha in the treated variety; thickening of plantings to the optimal level in the 70x20 area of nutrition of mother root crops allows getting high seed yields. The research also notes that seeds grown in the southern forest-steppe of Western Siberia are characterized by good germination. Carrots seed production in Siberia is possible and the resulting seeds have high seeding qualities.

Abstract
Spring rape is the main oilseed crop in the non-chernozem zone of Russia, which includes Ryazan region. The area with the crop has increased to 60 thousand ha in the last five years. Rape, being an important oilseed crop, belongs to feed crops of the region. Sale of oilseeds brings agricultural enterprises high profit from the crop production industry. Clearfield technology of rape growing was studied on gray forest loamy soil in Ryazan region in comparison with conventional oilseed production technology. Clearfield technology is the combined action of Nopasaran herbicide and the use of special hybrids which are resistant to this herbicide. High crop efficiency does not depend largely on weather conditions, mainly due to activity of the two active substances, which determine the novelty and relevance of the studies. According to the research results, the highest average spring rape yield in the experiment was obtained at the first sowing period in the 1st decade of May. It was 20.8 dt/ha for hybrid Salsa KL. The maximum crop yields were observed on options using Clearfield, regardless of the sowing period. On average, the growth, development, yield and its structure of domestic Ratnik variety were not inferior to Ozorno hybrid. Sowing in the first decade of May can be recommended as the most productive one for spring rape in the southern part of the Non-Chernozem Zone of Russia.

Abstract
The most important direction of increasing the production of sunflower oilseeds is improvement of technology elements that provide a fuller use of the productivity potential in soil and climatic conditions of a particular region. In this regard, the aim of the research was to identify the varieties and hybrids of sunflower most adapted to the natural and climatic conditions of Ryazan region, accounting for different levels of mineral nutrition. In order to identify biological features and economically valuable traits, a field experiment was conducted in 2017–2019. Agrotechnical measures for the cultivation of sunflower were carried out in accordance with zonal recommendations. As a result of the studies, it was found that variety Poseidon 625 was the most adapted to the climatic conditions of Ryazan region. Sunflower plants of Poseidon 625 variety were noted to have the smallest height (158–172 cm), the largest leaf surface area (11.61–16.53 thousand m2/ha), the largest number of seeds formed in one basket (1,194–1,247 pcs), the largest mass of 1,000 seeds (49.9–59.8 g) and the highest yield (2.37–2.99 t/ha). On average, in 2017–2019, the introduction of full mineral nutrition in doses of N125P60K60 and N125P120K120 contributed to an increase in the yield of sunflower oil seeds by 0.06–0.45 and 0.07–0.62 t/ha, depending on the cultivated variety and hybrid.

Published: January 2021

Abstract
The quality and compliance with the requirements of motor oils used in operation is one of the key factors determining durability and reliability of the internal combustion engine (ICE). The operating conditions of motor oils in ICE have changed significantly with an improvement in the design of the engine, the increase in power, the increase in pressure in cylinders and the change in the torque of the crankshaft. The requirements to motor oils during operation are constantly increasing, the specified terms of oil drain interval are increased. The composition of motor oils has also changed, and the technologists are adjusting their finished oil compositions to increasing requirements. Thus, it is necessary to constantly monitor the state of oil during ICE operation, the use of traditional express methods of oil quality verification is not always possible for new brands. The study considers the theoretical justification for the application of the drop test for the brands of strongly alkaline oils – Vanellus C6 Global “BP” (U) 15W-40 and Neste Tyrbo LXE.

Abstract
The automation of agriculture increases labour productivity and contributes to an increase in the output of agricultural products, an increase in their quality. These processes are closely related to the application of industrial production technology in agriculture, the improvement of planning and management. Also, the improvement of product quality and the growth of labour productivity are associated with the development of automated control systems that contribute to the autonomous operation of entire agricultural complexes. This paper deals with the development of a mathematical model of a milking installation based on stepper motors. The authors of the work recreated the operation of the milking installation, taking into account the operation of the kinematic scheme of the robot and the dynamics of the stepping motors, positioning of its working body near the tops of the teats of the udder of the animal, which are automatically recognized using image analysis from the 3D TOF camera. The uniqueness of this model lies in the fact that various stages of the operation of an autonomous milking installation are concentrated in one software product. This technology makes it possible to study the effect of each stage separately on the static positioning error of the manipulator working body. The model has been tested, an acceptable accuracy of the results of the model operation is achieved. This model can be recommended for use for engineering calculations and the development of control algorithms for the movement of the working body of the manipulator.

Published: January 2021

Abstract
In agriculture, use of solar energy is of crucial importance for water heating and functioning of greenhouses. It becomes even more important in agricultural enterprises which are located far from electric energy transmission lines. Furthermore, in Russia the importance of solar energy for agricultural enterprises can be motivated by deterioration of electric energy transmission lines. The article is devoted to the development of a sun tracking algorithm for solar panels without using GPS or sensors. The tracking algorithm has been created on the basis of well-known astronomic methods for calculation of the Sun’s position in azimuth coordinates. The control diagram using the Arduino platform is presented. The authors’ program works for the calculation of the Sun’s position complete with evaluation of error. It also works well with servo drive units. The hardware and software bundle have shown acceptable error values which did not exceed 2 % while aligning the panels with the sun.
