It provides people nutrition and national food security. To obtain healthy potato planting material, propagation in vitro culture is carried out. The problem of increasing the propagation efficiency at this stage is very relevant and can be solved by optimizing the lighting parameters, including the spectral composition of the emitter. The review of published works mainly over the last 20 years concerning the study of the effect of LED lighting of different spectral composition and power on regenerated potato plants, grown in vitro, is given in this paper. Morphometric and physiological parameters of potato plants are given, which can be influenced by changing the spectral composition of illumination. Data on lighting recommendations for different varieties of potato are given. This review may be useful for organizations involved in potato micropropagation, as well as for research teams developing technologies for optimal potato cultivation.","PeriodicalId":504649,"journal":{"name":"Agricultural Science Euro-North-East","volume":"359 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139177688","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 purpose of the research is to establish the influence of the duration of the storage period of aeroponic minitubers on the growth, development and productivity of various potato varieties under field conditions. The research was carried out in 2020-2022 in the conditions of the Novosibirsk region, the soil is leached medium loamy chernozem. The objects of the research are aeroponic minitubers of early-ripening (Yuna, Terra, Legenda) and mid-ripening (Zlatka, Sokur) potato varieties for December, March and April harvesting periods. It was established that the storage period of minitubers of various varieties was 179-184 days when collected from an aeroponic installation in December, 91.7-118.3 days in March, 71.3-99.7 days in April. The use of minitubers as planting material for growing high-quality potato seeds is justified during the December and March harvesting periods. Potato plants from the December planting material had a germination rate of 98.5 %, germinated 20 days earlier, had a larger average leaf area, the initial yield on the first recording date was 2.6 times greater and the final yield was 1.4 times greater than the plants from the March planting material. Minitubers of the December period provided the highest yield (22.8 t/ha) and the yield of seed tubers (76.3 %), with March harvest time the corresponding values were lower by 6.8 t/ha and 15.9 %, with April harvest period – by 15.9 t/ha and 34,0 %. It is not practical to use minitubers of the April harvest time with a storage period of 91.7-118.3 days as planting material, since it is impossible to obtain yield for the most of the studied varieties. The Sokur (mid-ripening) and Terra (early-ripening) varieties showed the highest yields of 20.4 and 19.5 t/ha.","PeriodicalId":504649,"journal":{"name":"Agricultural Science Euro-North-East","volume":"184 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139178434","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 development of ergonomic ways of modern diagnosis of these pathologies at the early stages contributes to the maintenance of quantitative and qualitative indices of productivity of animals and to the extension of the time of their economic use. The liver with a great number of functions performed is subjected to the highest load. The aim of the article is to review the available clearance tests in order to diagnose the pathology of the hepatobiliary system of animals at the early stage, considering advantages and disadvantages of the tests. As the result of the search of themed issues in various bibliographic databases there have been selected 45 mostly cited scientific articles. The article reviews such clearance tests as indocyanine green clearance test, aminopyrine breath test, sorbitol elimination test, galactose elimination test, phenylalanine breath test, and hepatobiliary scintigraphy method. Functional tests allow not only diagnosing and differentiating hepatopathologies, but also visualizing their course and liver recovery. Unlike laboratory tests, clearance tests make it possible to evaluate the work of the liver in dynamics. The disadvantages of clearance tests are lack of information for their wide use and frequency of particular differences in elimination of specific substances. To reduce the proportion of existing shortcomings, it is possible to combine clearance tests with other laboratory methods for diagnosing hepatopathy in animals.","PeriodicalId":504649,"journal":{"name":"Agricultural Science Euro-North-East","volume":"593 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139177917","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 Boyarin spring barley variety is characterized by a high yield (up to 6.15 t/ha in 2017), in some years exceeding the Belgorod 100 standard (by 0.9 t/ha in 2018). The variety is medium-early, the duration of the growing season is from 76 to 97 days; forms a highly productive stem (390 pcs/m2) due to good survival and bushiness of plants (2.0 pcs/plant), has a strong straw and is characterized by high resistance to lodging (5.0 points). The weight of 1000 grains is up to 47 g, the nature is up to 683 g/l, the protein content in the grain is up to 12.2 %. According to the quality of grain, it belongs to the varieties of grain-forage use. Since 2023, the Boyarin variety has been included in the State Register of Breeding Achievements Approved for Use in the Volga-Vyatka region. The article provides a scheme for creating a new variety of spring barley Boyarin and its economic and biological characteristics. When developing elements of varietal technology, new biofertilizers (Azolene, Azotovite, Phosphatovite, Kalivite, Nitroslak) andbiofungicides (Pseudobacterin, Flavobacterin, Alirin) were tested, which were used to treat seeds and plants in the \"tillering\" and \"earing\" phases. In relatively arid vegetation conditions (HTC = 1.23), no statistically significant yield increases were obtained from the use of all the studied preparations. With excessive moisture during the growing season of plants (HTC = 2.20) relatively high yield increases (1.31-1.58 t/ha with LSD05 = 0.50) were obtained in variants using biofertilizers Phosphatovite (seed treatment), Azotovite (plant treatment in the \"earing\" phase) and Kaliivit (treatment of plants in the \"tillering\" phase). The best biological protection against root rot at the level of 60.5 % was provided by the treatment of seeds with Nitroslak biofertilizer, which is not only a nitrogen fixator and phosphate immobilizer, but it also contains a binary mixture of microorganisms antagonists of phytopathogens.","PeriodicalId":504649,"journal":{"name":"Agricultural Science Euro-North-East","volume":"503 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139178265","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}
