Abstract
The selection of green manure crops for the zones with insufficient and unstable moisture is an urgent issue of agriculture. The purpose of the work is to establish the influence of the species composition of green manure on soil fertility. The research on southern low-humus chernozem was conducted in FSBI “Research institute of agricultural chemistry” in 2016-2019. The climate of the area is continental, semi-arid. The average annual air temperature is 10.8°C, the amount of precipitation is 428 mm. Conducting the experiment, statistical processing of data was performed according to B.A. Dospekhov. Layout of the variants - systematic, repetition is three times. The area of the plots is 720 m2. The subject of the research is agrocenoses of green manure crops. The object of the study is the soil fertility change processes. Agrocenoses of winter rye and triticale, melilot and sainfoin ensured the highest dry matter yield (6-6.3 t/ha). The maximum entry of organic matter into the soil occurred when using agrocenoses of winter rye - 5.88 t/ha and triticale - 5.72 t/ha. Mixture of crops on the entry of organic matter into the soil was inferior to rye and triticale, but outperformed vetch by 17.9%. The greatest amount of nitrogen was contained in the biomass of melilot and Sainfoin - 156 and 142 kg/ha, and in the mixture of winter crops - 108 kg/ha of nitrogen. The mixture combined the positive properties of its constituent crops: high and stable yield of dry and organic matter, nitrogen, phosphorus and potassium. Due to mineralization of the organic matter of green manure crops, there was an increase in nitrate nitrogen in the arable horizon from 1.0-2.4 to 12.0-22.8 mg/kg of soil.

Abstract
The authors of this article describe the experience of biotechnology for growing Australian crayfish in conditions of pond cultivation in a group of ponds, operating in an intensive mode, used in an isolated area close by a natural water source in the Astrakhan region. In the presented article, research is aimed to clarify the main biotechnological indicators that increase the efficiency of cultivation in pond conditions. The conditions of transportation, the duration of transportation, and the density of crayfish in ponds with an area of 1 hectare have been clarified. The presented food recipe with the specification of the percentage of nutrients as additional feeding, organized when growing in ponds according to the food recipe itself, increases not only the growth rate but also the hemolymph protein concentration, which indirectly proves the satisfactory conditions for keeping aquaculture objects. Monitoring for the biotechnology of growing Australian crayfish in pond conditions: own developed food recipe, biological and physiological testing of key indicators such as hydrochemical indicators of water, hydrobiological indicators of the concentration of, and physiological indicators for determining the so-called biotechnological norm, which will add additional missing information on this aquaculture object.

Abstract
To create recommendations regarding the technological process of growing objects of warm-water aquaculture, the health of individuals in the created conditions of maintain is a necessary study. Taking into account the similarity of the necessary conditions for the organization of growing warm-water aquaculture objects, it is important to monitor the indicators that are bioindicators of homeostasis constants with a projection on the conditions of maintain, for subsequent adjustment of satisfactory conditions of maintain. First of all, these are hematological and biochemical bioindicators that determine the general characteristics of blood in the case of fish objects of sterlet and hemolymph in the case of crustacean objects of Australian freshwater crayfish and the concentration index of total serum protein that determines the “physiological norm”. When growing sterlet, a high level of total blood protein was established at 40.14±1.73 g/l and the hemolymph of the Australian freshwater crayfish was determined to have a protein concentration of 40.8±4.5 g/l. The presented analysis of bioindicators complements the missing information for monitoring the data of representatives of warm-water aquaculture, which will be valuable for specialists engaged in breeding these objects.
Evaluation of genetic polymorphism of proteins in stellate sturgeon Acipenser stellatus (Pall) in aquaculture with reference to economically valuable traits
Authors: Shishanova Elena , Shishanov Grigory , Isaev Dmitry 
Published: December 2021

Abstract
One of the main goals of sturgeon aquaculture is the restoration and renewal of wild populations of sturgeon fish in nature, which creates a tension between selective breeding with maintenance of valuable economic traits in a homozygous state and the need to conserve genetic diversity ensuring fitness in natural environments. It is generally assumed that important economic characteristics, such as body weight and size, growth rate, fecundity, etc., as well as fitness in fish, are associated with heterozygosity and genetic polymorphism of some key metabolic enzymes. It remains unclear whether aquaculture conditions can be as a whole selection factor in favor of certain allelic variants of these enzymes. To establish the relationship between some economic traits and enzymatic polymorphism, we studied the distribution of allelic variants of LDH-3, AAT-2, FGM, and Est enzymes in stellate sturgeon reared in aquaculture. We revealed a frequency bias of some allelic variants of the studied enzymes in a cohort of fish from the generation bred in aquaculture compared to the frequencies of those alleles in wild natural populations. Our study suggests that industrial breeding promotes selection in the direction of reducing size but increasing survival rates, which correlates with certain allelic variants.

Abstract
Carp breeding in Western Siberia has been going on for about 1960. Here two breeds of Sarboyan and Altai mirror carp were bred and put into economic use. The Sarboyan carp is a cross with 1/8 of the blood of the Amur carp. The Sarboyan carp has now disappeared in the fish farm, there are its descendants who have not been subjected to selection for 4 generations. To work on the selection of a new intra-breed type, specimens corresponding to classes 1 and 2 were selected from the head reservoir of the fish farm. Specimens of class 1 accounted for 2.6% of all selected fish. The analysis of the exterior showed that as a result of the lack of selection and mating disorderly, the physique of the fish changed. It deviated and is closer to the wild Amur carp. In males, the length index increased by 21.30%, the body became longer and smaller. In females, the same changes are observed in exterior, in addition, there is a decrease in fertility, since in the studied population the correlation between progenity and fecundity is 0.42-0.72. The relative growth of the main exterior features has decreased.

Published: December 2021

Abstract
The energy-efficient crushing of dried fibrous plant materials is usually hampered when the sieve holes of the crushing unit are clogged with not-grinded particles. The purpose of the study was to investigate the crushing process of dried plant raw material and determine the effect of the operating modes of a crushing unit on the crushing quality and energy consumption. The experimental tool was a rotary crushing unit with alternate knives and hammers. The objects of crushing were dried leafy mass of grass. There has been found that when the linear speed of the rotor knives rises, the fractional composition of the crushed product changes, namely, the proportion of fine fraction (less than 1.3 mm) increases and the proportion of large particles (more than 1.3 mm) reduces. The rise of the knives speed results in productivity improvement, but increases energy consumption of crushing as well. The optimal range of changing the knives’ speed was 55…65 m·s-1 to obtain a product of the required fractional composition. The use of the method of crushing dried fibrous plant materials and a rotary crushing unit will allow organizing energy-efficient crushing of dried leafy stem mass.

Published: December 2021

Abstract
The article presents ways to obtain alternative sources of protein and fat from perennial crops and insects. The main properties of the material influencing the process of extracting fat from insects are considered. According to the results of the studies, the optimal technological parameters of the dried Hermetia illucens larva were revealed when pressing the fat. The optimum mass fraction of moisture is 15%. At a moisture content of insect biomass of 15%, fat filtration occurs at a pressure of 2.5 MPa. Microwave treatment of the material before pressing reduces the pressure at which the fat is squeezed out – 1.9 MPa at a material heating power of 1000 W. The intensity of heating does not significantly affect the acid number of the fat. Therefore, the most optimal heating power is 1000 W. The granulometric composition of the insect biomass also influences the fat squeezing process. Before pressing the fat, it is necessary to grind the larva to the size of particles passing through a 1 mm sieve in an amount of at least 60% of the total mass. The preparation of the material for the squeezing process has a significant effect on the energy consumption of the process. With a granulometric composition of particles of 1 mm, a moisture content of 15% and heating with a microwave power of 1000 W to 60° C, it provides a process that is 2 times less energy-intensive compared to pressing fat from an unprepared material.

Abstract
The performance of spring field work in the best agrotechnical terms and with high quality is provided by well-trained equipment. The recommendations provide for four stages of work related to the adjustment of machines and quality control of technological operations: control of working bodies and components of machines after repairs or new ones are delivered; technological adjustments of machines; verification of technological adjustments in the field; quality control of technological operations in the field. As a criterion for the efficiency of the use of energy resources in agriculture, some foreign sources recommend the output of agricultural products per unit of energy used. The article describes the regression equations that can be used to characterize the process of grinding sedge hummocks on the root with a milling cutter. Statistically significant factors affecting the degree of grinding of the hummock are the speed of rotation of the working body, the distance between the tiers of knives, the speed of movement, the angle of taper of the rotor and the angle between the knives on adjacent tiers. Thus, layer-by-layer milling most fully meets the requirements of pre-sowing tillage on land in the oatmeal zone.

Abstract
The development of agricultural technologies, the mechanization of the cultivation of ordinary crops for a long time has gone differently in different ways. The working bodies of agricultural machines process various materials, the number of which is increasing. In addition, the way the same material is processed often changes when trying to improve agricultural technologies. All this forces us to create new mechanisms of agriculture that were previously known. The use of replaceable gear bodies on flat cutting cultivators helps to reduce the energy intensity the process and improve the quality of non-falling soil. To protect against it, various agricultural techniques are recommended: plowing along the entire slope, deepening the arable layer, the formation of irregularities on the surface of arable land in the form of holes, intermittent furrows. The article describes the mechanized protection of the soil of the technological process and technical means for growing crops on erosive lands on the slope. Methodology for improving agricultural machinery for working on the slope of erosive dangerous lands. Ways to increase the stability of the movement of agricultural machines on slopes to improve the quality of technological operations are justified. The operating mode of the active disk needle is described.

Abstract
Tracking devices are increasingly used in automatic control systems for mobile agricultural machines. Many elements are regulated by standards and specifications, and it is of scientific and practical interest to establish a correspondence between the reliability of restored parts and connections with the reliability of machines. This is due to many reasons, one of which is a decrease in the technical potential of the village: the composition of the machine and tractor fleet is decreasing, the physical and moral wear of equipment is progressing. Repair and maintenance of cars due to the price arbitrariness of intermediary structures, mainly on the part of collective farms and farms. For this reason, the reliability and reliability of the machine park of rural producers remain low, negatively affects the agrotechnical timing of mechanized work, their cost. In accordance with the standard technology, standards of labor costs for the repair of machines, standards for the consumption of materials needed for repair, and standards for the consumption of spare parts were created. The economic feasibility of restoring parts is usually assessed by comparing the cost of a new part and the cost of repairing a worn one.

Published: December 2021

Abstract
In the process of tightening the rings of the lower seine line, significant forces of hydrodynamic resistance of the netting can capsize the vessel or pull it into the encircled seine area. There is a risk of damage to the propeller-rudder system of the vessel. The list and trim of a fishing vessel can occur. It affects the safety and comfort of the crew, leads to malfunctions of fishing equipment and mechanisms, and can cause accidents. During the vessel’s operation, there are a number of measures to improve stability. However, when designing fishing equipment, it is necessary to know the forces acting from the seine side on the vessel. The article discusses the relationship between the vessel and the seine during purse seining. On the basis of the developed mathematical model of the tension force of the purse rope, taking into account the geometrical parameters of the warp during purse seining, conditions for stability of the “vessel-purse seine” system were obtained.

System risk assessment based on the probabilistic model “exposure-susceptibility” at the enterprises of storage and processing of vegetable agricultural products
Authors: Cheremisin A , Esipov Y , Traypichkin S , Bukreeva A 
Published: December 2021

Abstract
At present, elements of probabilistic safety and risk assessment have been introduced into the design and analysis of complex technical systems, one of the main disadvantages of which is the difficulty due to the selection of initial data in the form of probabilities of initiating events. As a consequence, the use of known methodologies for quantifying risk can lead to either underestimation of threats or unreasonably high security costs. On the example of an enterprise for the storage and processing of vegetable agricultural products, an approach was considered for assessing the risk of a technical system based on the probabilistic model “exposure-susceptibility”.
