Research methods: hypothesis, experiment, field observation, laboratory, visual and comparative calculation method. Research results: Field studies were conducted in soil and climatic conditions of Western Ukraine. The experimental field was characterized by sod-podzolic light loam soils. Climatic conditions of research – the average daily air temperature during the growing season of corn - +16.9 ° C, rainfall – 263 mm. Väderstad's eight-row Tempo 8 seed drill, which was aggregated with a Fendt 722 tractor, was used in the research. In the process of performing the technological operation of such a sowing unit, two sowing machines work on the tracks of the tractor wheels. According to the results of research it was established that the number of cobs in the rows on the tracks of the tractor was 42.2-49.6 thousand pieces. / ha and was lower by 6.4-8.8 thousand units / ha (11.4-17.2 %) compared to uncompacted areas of the field. There was also a decrease in the weight of grain in the cob on the tracks of the tractor by 4-30 g, depending on the hybrid. The grain yield of corn sown on the tracks of the tractor was lower by 2.27-2.51 t/ha (16.5-27.9 %) compared to this figure on uncompacted rows. Seed yield of the studied hybrids (average value for all eight rows of rows) is 8.33-13.21 t/ha. Due to the fact that in ¼ rows (in two rows on the tracks of the tractor) recorded lower yields, the average yield of corn grain decreased by 0.57-0.66 t/ha (4.1-6.9 %) compared to this figure on uncompacted rows. Due to the negative impact of the running energy system on the soil during sowing, the economic indicators of maize cultivation deteriorate. If the soil compaction is eliminated or minimized by the running gear of the energy source, the profit may increase and according to the studied maize hybrids will be 19217-53921 UAH / ha. As a result of soil compaction by running systems of the sowing unit, the profit is reduced by 4104-4536 UAH/ha. Conclusions. In the rows located on the tracks of the tractor, due to soil compaction, the conditions of plant growth and development deteriorate, which is reflected in lower indicators of crop structure elements (number of cobs, grain weight of cobs, etc.) and reduced yield and efficiency of maize cultivation. Key words: research, corn, tractor running system, soil compaction, yield, efficiency.","PeriodicalId":34711,"journal":{"name":"Tekhnikotekhnologichni aspekti rozvitku ta viprobuvannia novoyi tekhniki i tekhnologii dlia sil''s''kogo gospodarstva Ukrayini","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46619666","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}

Research methods. Analytical research on the relevance of modernization of small pig farms with a closed production cycle was carried out by the method of processing existing scientific and informational reports. Research results. When organizing pork production at the farm level, the most important measures should be on the production flow, formation of homogeneous technological groups of pigs, herd reproduction, sow keeping, quality of feed rations, creating a proper microclimate, compliance with production technology. One of the main factors holding back the growth of pork production is the lack of feed, their low quality and the constant shortage of digestible protein in feed rations for pigs. The existing premises of small pig farms do not fully meet modern requirements for the maintenance of various technological groups of pigs. The further development of pig farming requires important issues related to sanitary protection zones, animal welfare and environmental protection. It is important to ensure biosafety in pig farming and to implement appropriate veterinary practices and standards. In most pork farms, the genetic potential of domestic pig breeds is now used for reproductive qualities by only 45-50 %, and for fattening by 20-25 %. In the system of qualitative improvement of the breeding stock of farms, the disadvantage is the unsystematic use of reared young pigs, 70% of the products are sold to meat processing plants. When modernizing small pig farms with a full cycle of pork production, among other things, it is necessary to take into account the size and resource characteristics of basic farms to achieve high efficiency of production.

Methods and materials. Studies of the process of drying, content and evaporation of moisture from corn grain were carried out based on the results of experimental studies of the quality of functioning of the grain dryer Stela Agro Dry MDB-XN 4/15-SU. The dryer was located on the open area of the grain elevator. The formation of the heating agent with a temperature of +110 °C was carried out with the participation of a gas flat burner \"Roses & Wayler\". The process of supplying the coolant to the dryer shaft was stable and homogeneous. Drying was carried out in a continuous rigid mode: a significant reduction in moisture - from 35 % to 13.5 % in one pass through the grain dryer. Its productivity under such conditions was 60 t / h. The time of passage of grain through the dryer - from loading to unloading was 5 hours. Measurement of grain moisture in the stream, along the height of the mine, was carried out using the humidity sensors of the dryer. The measured data were recorded and displayed as digital measurement results. Assessment of grain quality was performed visually - organoleptic method. To analyze the content and evaporation of moisture in the corn grain, depending on the drying time, graphical dependences are built by modeling. Results. According to the results of one-factor experimental studies, statistical data were obtained on the moisture content of corn grain and during its evaporation during the drying time - 5 hours. In accordance with them, graphs of changes in the content and evaporation of moisture during the drying of grain. The results show that at the beginning of drying and at a significant initial grain moisture (35 %), the dryer reduces the humidity to 7 % in one hour. At the final stage of drying, when the grain moisture is close to the condition (for example, 15.5 % or 13.5 %), the decrease in moisture per hour of drying is only 1 %. In general, grain moisture decreased by 21.5 % in one pass through the dryer. This mode of drying grain in one pass of the grain through the dryer is characterized as rigid. Organoleptic evaluation shows that despite this - a strict regime of drying the grain has retained all the initial indicators that characterize its high quality. This is achieved due to the ability of the dryer to reduce a small amount of moisture at the final stage of drying - only 3-2 % for 1 hour of drying. Analysis of the research results shows that with the beginning of drying the moisture content in the grain decreases. For the duration of drying up to 3 hours there is an intensive release of moisture through the shell of the grain: the return of moisture by the grain for 1 hour of drying is significant and intense and ranges from 7 % to 4 %.

Research methods. Systematization of factors influencing the quality of pig products is carried out by summarizing many years of research in the field on topical issues - the quality and technological properties of pig products, including taking into account modern requirements. Research results. When keeping pigs, it is necessary to create favorable conditions close to natural for the protection and preservation of animals. In the process of production of quality pig products, the leading role belongs to zoohygiene, which combines the following components: pig health, conditions of keeping and care of pigs, sanitary condition in the pigsty. During the production of products on pig farms, every effort should be made to maintain the proper health of pigs, which is identified by the physiological state of the animals. The physiological state of animals is influenced by a number of factors: pathogens of infectious diseases, genetic factors, the environment. The quality of pig production also depends on the conditions of keeping and care of pigs for such factors as technological areas, manure, litter, playgrounds, environment. It is necessary to adhere to the normative technological areas when keeping pigs. The level of protein in animal feed is important for improving the quality of pork. All animals in the technology group must have access to feed at the same time. Water quality has a significant impact on the technological properties of pig products. Modern requirements for microclimate indicators in piggeries are as follows: air temperature 15-20 °C, for newborn piglets - up to 30 °C, relative humidity 50-80 %, air velocity 0,15-0,5 m/s, maximum level harmful gases in the air: NH 320 ppm; CO - 1500-3000 ppm; H S - 5 ppm, pollination level 10 mg/m3.

The aim of the work is to substantiate the modern organization of technical operation of combine harvesters, which is carried out by a network of parallel-functioning queuing chains. The practical result will be the formation of a model of technical control of the requirements of individual systems, which will initially be addressed using the terminology adopted by the theory of queuing, and recommendations will be given on the specific use of the solutions. Research methods. The methodological basis of the work is the generalization and analysis of known scientific results regarding the modern organization of technical operation of combine harvesters, carried out by a network of parallel queuing chains, and the use of requirements division algorithm and queuing theory. Analytical method and comparative analysis were used to form a scientific problem, determine the purpose and set research objectives. When creating empirical models, the main provisions of the theory of queuing, systems of stationary service devices, block diagrams of the failure distribution algorithm are used. The results of the study. The article considers the data, which is considered to be the modern organization of technical operation control of combine harvesters by network, which consists of a finite number of parallel operating queuing chains with serial numbers . In the network at random moments of time from an external source receives service requirements. The issues of choosing a chain for service requirements were considered. Since each chain is designed to restore a particular model of machine by performing one or another type of technical control of the combine harvester, the choice of chain was determined by the parameters ω_i and ξ_i received applications. It was taken into account that the total number of queuing chains Β, as a rule, is less than the number of types of technical control of the number of models of combine harvesters in the park ε, because in the same chain can perform technical control of several types and models of combine harvesters. For each specific case of organization of the network of technical operation in accordance with the accepted specialization of individual chains, a matrix of chain selection for servicing the application according to its parameters and can be compiled. A similar matrix, in which each pair of possible values corresponds to a specific chain number ε, can be easily constructed for any specific case of a given organization and specialization of the network of technical operation of combine harvesters.
