Unpleasant odor takes place as a result of anaerobic decomposition of the manure and also due to liquid slurry at the pig-breeding facility. Despite the fact, that the effect of unpleasant odor on human health is under-investigated, the people suffer natural aversion to the smell of manure. The smell of swine manure can be an unpleasant factor affecting the quality of the life of people living in the cities close to the pig-breeding complexes and also have an effect on the price of the real estate located within this area. Tightening of standards regulating the level of odor can also be a limiting factor for this branch of industry. Detailed research aimed at the selection of the optional composition of chemical reagents for deodoration and disinfection of liquid slurry waste at a pig breeding complex is presented. It has been determined, that the effect of disinfection and suppression of unpleasant odor for a long time is provided by the composition of ammonium persulphate, peracetic acid and formalin, the composition that contains sulphuric acid, sodium hypochlorite and sodium hydroxide and finally, the composition that contains sodium nitrite and ammonium molybdate. It was showed that the abovementioned mixtures are effective in relation to the samples of manure in laboratory (the volume of manure taken for the experiment was 200-400 ml), as well as semi-industrial conditions (the volume of manure – 80 liters). The manure mixtures obtained as a result of such treatment are environmentally friendly and can be used for the production of organo-mineral fertilizers.","PeriodicalId":41146,"journal":{"name":"Proceedings of the National Academy of Sciences of Belarus-Agrarian Series","volume":"49 1","pages":""},"PeriodicalIF":0.2,"publicationDate":"2023-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75171073","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 results of phytopathological situation monitoring in crops of spring wheat varieties are presented in the paper. Studies were carried out in 2019–2021 in the laboratory of phytopathology and in the experimental field of the Institute of Plant Protection. Standard methods in phytopathology were used during the work. The main criteria for assessing the degree of plant infestation were disease development (%) and area under disease process curve (AUDPC, in conditional units). Analysis of phytopathological state of spring wheat crops showed that during the growing season the crop varieties were affected by diseases of vegetative and generative organs: root and byroot rots, powdery mildew, leaf and ear septoriosis, pyrenophorosis, brown rust, and fusariosis of ear. Root rot, leaf spot disease, septoriosis, and spikelet fusariosis are among the dominant diseases annually present in spring wheat crops. Variety differences in disease incidence are a factor influencing the emerging phytopathological situation in the crop. Cultivation of resistant varieties reduces the risk of epiphytotics. According to the sum of infectious loads experienced by the plants during the whole period of vegetation, the evaluated varieties of spring wheat were ranked in ascending order: Lyubava (60,5 %), Slavyanka (61,9 %), Sudarynya (66,9 %), Laska (71,3 %), and Darya (83,9 %). The results of the studies allow to give preference to the most interesting varieties, based on the available opportunities to ensure the proper level of protection against diseases.","PeriodicalId":41146,"journal":{"name":"Proceedings of the National Academy of Sciences of Belarus-Agrarian Series","volume":"35 1","pages":""},"PeriodicalIF":0.2,"publicationDate":"2023-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82646592","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}

A great influence on labor productivity and specific operating costs is exerted by energyand material-intensive operations, such as plowing and harvesting. The main patterns of the plowing operation, which is a complex technical system, is connected with the use of a large volume of agrotechnological, technical, operational, resource and economic information (operation duration, working length of the harrow, physical and mechanical properties of soil, depth of treatment, permissible interval of the unit speed, fuel and energy, engine power and traction characteristics, width of the unit, economic indicators, etc.) are considered. Currently, as a result of introduction of computer mathematics systems, there are effective methods available for studying complex technical systems, allowing for multi-factor modeling and multi-criteria optimization of the production processes and formation of a set of machines by system analysis. A prerequisite for a complete and comprehensive description of the functioning of a complex technical system is the presence of conflicting optimization parameters, as well as a complete set of independent control factors significantly affecting these parameters. A distinctive feature of the proposed method is to determine not one optimal solution, but a set of Paretooptimal solutions, giving the producer new opportunities of choice when organizing the production processes, increasing the efficiency of plowing operation and, consequently, the profitability of grain production in general. Therefore, increasing productivity at permissible specific operating costs through the formation of a rational set of machines and modes of its operation under specific conditions of production is an important scientific and engineering task. A mathematical illustration of the method is provided for natural-production conditions of the Republic of Belarus.","PeriodicalId":41146,"journal":{"name":"Proceedings of the National Academy of Sciences of Belarus-Agrarian Series","volume":"60 1","pages":""},"PeriodicalIF":0.2,"publicationDate":"2023-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82206903","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}

At the same time, an important aspect when growing microgreens in a closed controlled environment is lighting, which is both a signal for growth and development and a source of energy for higher plants. Plants adapt to the conditions of the light environment not only via changes in morphophysiological parameters, but also via restructuring their light-collecting complex. One of the most important parameters of the lighting mode is the photon flux density – the intensity of illumination, which significantly affects both the growth of biomass and the accumulation of secondary metabolites. The results of a comparative study of the influence of the intensity of LED lighting are presented (50, 100, 150, 200, 250 μm/m2·s) for the content of chlorophylls, carotenoids and ß-carotene, dry, tannin and pectin substances, free organic, ascorbic and hydroxy acids in the samples of white cabbage microgreens, soluble sugars, the main groups of bioflavonoids – mainly anthocyanins, leucoanthocyanins, catechins, flavonols and the indicator of the sugar acid index. It has been determined that the leading position in the experiment in terms of the integral level of nutritional vitamin value of this product, exceeding that in the control by 1.4 times, belonged to the variant of the experiment with a minimum intensity of LED lighting of 50 μm/m2·s, whereas for the variant with an intensity of lighting of 150 μm/m2·s, a lag in this regard from the control by 1.1 times and, accordingly, from more successful variants of the experiment by 1.2–1.6 times, which allowed to consider it ineffective. The novelty of the research lies in the fact that for the first time in the conditions of the republic, a comprehensive biochemical study of samples of white cabbage grown at different intensities of LED lighting was carried out, which made it possible to recommend this vegetable crop for industrial production of micro-greenery.","PeriodicalId":41146,"journal":{"name":"Proceedings of the National Academy of Sciences of Belarus-Agrarian Series","volume":"64 6 1","pages":""},"PeriodicalIF":0.2,"publicationDate":"2023-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77248221","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}

In the course of the experimental part, generally accepted and special research methods and techniques were used; the peculiarities of the extraction and fermentation processes were studied. This is the first time when, in the technology of manufacturing apple distillates, a method was used to reduce the amount of the resulting head fraction during fractional distillation, and the prospects for the reuse of a new by-product of fractional distillation – an intermediate fraction – were scientifically substantiated, as well as diffusion juice obtained from apple pomace was involved at the fermentation stage. The uniqueness also lies in the fact that all the techniques are combined into a single integrated approach. As a result, a scientifically sound, improved and cost-effective technology for production of apple distillates with complex processing of secondary raw materials of winemaking has been developed, which makes it possible to increase the level of economic feasibility and efficiency of the industry, and is the basis for innovative economic development aimed at import substitution.

At the same time, the unprecedented sanctions policy against the Republic of Belarus required a more sustainable agri-food system and the development of fundamentally new scientifically substantiated directions for diversifying export supplies. Step-by-step methodology has been developed for forecasting the development of foreign markets for agri-food products, which is a set of goals, objectives, an algorithm for conducting and an analytical product based on Microsoft Excel analysis tools, based on a set of factors impacting the trading process. In addition, a system of economic indicators for assessing the functioning of food markets and mechanisms for product access, including customs-tariff and non-tariff measures, has been substantiated. The methodology was tested based on example of the member states of the Eurasian Economic Union (EAEU) as the main trading partners of the Republic of Belarus, as well as the countries of Asia (Vietnam, Iran, China, Singapore) and Africa (Algeria, Egypt). The scientific novelty of the development lies in using a step-by-step algorithm for assessing the market situation of a particular country when making rational management decisions on the effective use of the existing potential and resources of agro-industrial complex organizations in order to enter existing and new markets (segments). These developments can be used by the Ministry of Agriculture and Food of the Republic of Belarus, the “Belgospischeprom” concern and other subjects of the agricultural business in preparation of analytical reviews of the country’s market environments for agricultural and food products.","PeriodicalId":41146,"journal":{"name":"Proceedings of the National Academy of Sciences of Belarus-Agrarian Series","volume":"18 1","pages":""},"PeriodicalIF":0.2,"publicationDate":"2023-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83488399","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}

Materials on the study of the genetic potential of animals with due consideration of the following economically useful traits are presented – growth intensity, milk productivity, reproductive performance, productive longevity and disease resistance. It has been proven that this can only be achieved through targeted selection and the creation of a breeding base. It has been established that the study of allelic polymorphism of cattle longevity marker genes is a relevant area in the conditions of the Republic of Belarus. At the present stage, more and more attention is being paid to the study of polymorphism of DNA markers of production traits of farm animals. Using them as methods for a more objective assessment of breeding values of animals can accelerate and stabilize the management of selection processes.
