The research aims to analyse the profitability of agricultural production, influencing factors and determination of directions for its improvement. The methodological approach is based on the analysis of statistical data on changes in production profitability; method of average values – to obtain the average value of indicators; comparison method – to compare data on profitability and productivity between types of products; graphic method – to display the results; method of generalization – for summarizing information about agricultural production. The main results that were obtained within the scope of this study should cover the analysis of the profitability of agricultural production by its types and crop yield and regions of the country in the conditions of the impact of negative factors on the agricultural sector during the period of martial law (in particular, the reduction of land suitable for agriculture, blocking many ways to sell products, complicating the supply of mineral fertilizers and other goods necessary for the functioning of the agrarian sector) and highlight directions for increasing profitability, namely increasing the yield of certain types of crops; reduction of feed costs for feeding animals by growing feed and electricity production efficiency through the use of renewable energy sources (sun, wind, biomass energy); development of pig meat production by increasing their population and quality of nutrition; creation of added value from products obtained by the producer on his own land, which will contribute to increased profitability and successful development of agriculture. Analysis of the supply and demand balance of grain and leguminous crops showed that their production exceeds the need for consumption of all types of grain.

The sensitivity of apple cultivars that have been planted so far and continue to be planted to this pest diverges in different cultivars. The research aims to determine the main elements of Cydia Pomonella control using sex pheromones and environmentally friendly insecticides. To achieve the goal, an experiment was conducted in the village of Dvoran in the Korcha region on three apple cultivars: Golden Delicious, Star King, and Granny Smith. On the trees of these varieties, traps with sex pheromones were used and environmentally friendly insecticides were utilised. The study found that using sex pheromone traps to monitor Cydia Pomonella is simple and less expensive for apple growers. The Spinosad medicine is the most effective in terms of protection against the pest, the second being Indoxacarb. Golden Delicious and Granny Smith cultivars had the lowest level of pest infestation, while the Star King cultivar was the most affected by Cydia Pomonella. It has also been established that apple fruits do not contain toxic residues, and the ecosystem remains clean. Additionally, the use of sex pheromones can be part of an integrated pest management approach that combines different control methods to sustainably manage pest populations in gardens. The practical significance of the obtained results is that they provide apple growers with a safe and effective method of controlling Cydia pomonella populations in their orchards. In addition, the scientific basis for the use of sex pheromones as a method of pest control can contribute to the implementation of sustainable control methods in apple production","PeriodicalId":52817,"journal":{"name":"Naukovi gorizonti","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46337440","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 search for ways to regulate the resistance of fruit trees to stressors is an urgent issue for the world community. The use of beneficial microorganisms to inoculate plant roots helps reduce the use of synthetic substances and is an alternative for sustainable horticulture. The purpose of the study is to identify the specific features of the effect of root inoculation by mycorrhizal fungi on the reaction of sweet cherries to develop strategies for managing the production of fruit products. The study was conducted during 2018- 2020 in the sweet sweet cherry orchard of the southern steppe subzone of Ukraine. Such research methods as field, laboratory, biochemical, physiological, and statistical were used. The regularities of the influence of mycorrhizal fungi on the total moisture content and water-holding capacity of sweet cherry leaves were examined. In the first year of studies on endomycorrhizal root inoculation, these indicators were higher compared to the control group. The positive effect of endo-ectomycorrhiza on the waterholding capacity of sweet cherry leaves was elucidated. The total leaf surface and the content of green pigments in the leaves were determined as one of the main indicators of the photosynthetic potential of a fruit crop. The effect of inoculation of sweet cherry roots by mycorrhizal fungi on the ratio of chlorophylls (a/b) in leaves was established. The parameters of the content of total nitrogen, phosphorus, and potassium in sweet cherry leaves were determined. The use of mycorrhizal fungi increases the adaptive properties of sweet cherry trees to stressful factors, namely, arid conditions in the south of Ukraine.

The research aims to study the influence of different inorganic phosphorus content in the aquatic environment on the indicators of phosphorus-calcium exchange in fish. The methods of thin-layer chromatography and variational statistics were used. Glandular tissues of the gills, liver and kidneys of fish were analyzed. To study the influence of inorganic phosphorus in the water environment on some indicators of intracellular metabolism, mitochondria were isolated in osmoregulatory organs. It was found that when the concentration of phosphorus increases to 0.3-0.6 mg/L in the water environment, it accumulates in the liver, and gills and decreases in the kidneys, while the concentration is maintained at a relatively constant level in the blood serum of fish. An increase in the concentration of inorganic phosphorus in the water environment significantly affects the processes of energy generation in the mitochondria of fish livers. A change in the phosphorus content in the habitat of fish has a significant impact on tissue bioenergetic processes, which is manifested in a change in the adenosine triphosphate content, and alkaline phosphatase activity.

During the experiment, diagnostic methods were used to select plant leaves, identify, record, and analyse the affected leaves of viburnum plants by the Pseudomonas syringae pv. viburni bacterium. A method to avoid or reduce the risk of bacterial blights was developed. It was determined that various approaches can be used to prevent bacterial diseases in plants of the Viburnum L. genus, such as selecting more disease-resistant varieties, collecting and destroying fallen leaves and branches after pruning, and following agricultural techniques and gardening practices. For chemical control, copper-based bactericidal preparations, such as copper hydroxide or copper sulfate can be used, which are recommended for use in autumn and spring before budding. Performing these actions will help to prevent the manifestation of bacterial diseases in plants. It is proved that in the conditions of the Northern Forest-Steppe of Ukraine in the system of fruit gardening, it is advisable to grow high- and medium-resistant genotypes of Viburnum vulgaris of the Institute of Horticulture of the National Academy of Agrarian Sciences of Ukraine against bacterial leaf spotting.
