The Effect of Bud Loading on the Grape Growth, Yield, and Quality Indicators of the Nrneni Grape Variety
2024
Grigoryan, B.A. | Ohanyan, A.I.
In the Armavir marz of the Republic of Armenia, the effect of the load of buds was studied on the growth, yield, and quality indicators of the Nrneni grape variety. This grape variety was created at the Armenian Agricultural Institute, by crossing the 1-17-1 (Alicant Bushe x Cabernet Sauvignon) hybrid form and the Georgian Saperavi varieties. The Nrneni grape variety is lateripening, moderately high-growing, with low frost resistance and high fungal disease resistance. Experimental vineyards were planted at a planting density of 2.5x1.5 m. The vines were formed according to a low-stem multi-arm fan-shaped formation: The load of the vines was studied at 20, 30, 40, and 50 buds. Research findings related to shoot growth, ripening, and harvest quality enable us to recommend the optimal vine load for the Nrneni grape variety in the Armavir marz region. Based on these studies, we suggest maintaining a load of 30–40 buds per vine.

2024
Grigoryan, B.A. | Samvelyan, A.G. | Mikayelyan, M.N. | Ohanyan, A.I.
The ratio of stem fruit, skin, pulp, juice, and seeds is determined by mechanical analysis. A grapevine›s ratio between these components is crucial for winemaking, both in terms of yield and quality. This work aims to determine the mechanical composition of the local, less common varieties, Voskehat and Chilar. The weight of the bunch and berries, the number of berries in the bunch, as well as the weight of the seeds and the skin of the ridges are determined. The structure of the bunch, the composition of the berries, and the indicator of the composition of the bunch were calculated: For Chilar grape varieties, this indicator was higher at 1.8, while for Voskehat grape varieties, it was 1.4. Higher juice yields mean higher efficiency of wine production and lower wine costs for technical varieties.

2024
Markaryan, S.Y. | Markaryan, A.S. | Aghasaryan, A.A. | Mazmanyan, A.G.
Seven different types of grain grinders were tested under production conditions. Grain grinders with vertical and horizontal cutting organs were selected for investment in mass and feed production. Their technical, economic parameters, and operational reliability were investigated. Based on the statistical evaluation of the operational reliability of grain grinders, the average statistical values of their readiness factor were calculated, which was Kp=0.8 for UHM-2.2, and 0.51 for HHUM-2.2. Meanwhile, it is established that the readiness factor of the machines and equipment used in animal husbandry and feed production should be no less than 0.94. All defects of nodes and machine parts were identified, also scientific and practical recommendations were made to eliminate and improve operational reliability. It has been established that in the case of identifying defects arising during the long-term operation of these grain grinders, eliminating them with appropriate methods, and finally improving their structure and function, it is possible to successfully organize their mass production and implementation in agriculture, particularly feed production.

2024
Badalyan, M.V. | Dilanyan, V.T. | Avagyan, L.S. | Aloyan, T.B.
TIn the current period of agricultural management, when the task is to obtain new breeds of farm animals following modern socio-economic, regional, and natural-geographical requirements and to improve the existing ones, the problem of using the rich gene pool of wild relatives very often arises. It should be noted, however, that the genetic potential of the Armenian Mouflon was not used during the creation of agricultural animals, particularly sheep in Armenia. This was due to several biological barriers, which are currently surmountable with the use of modern biotechnological methods, especially genomic selection. To resolve the issue, we carried out the genetic passportization and barcoding of the Armenian Mouflon kept in the Yerevan Zoo according to ISSR-PCR markers. Five of the 11 ISSR primers used during molecular-genetic research had high activity: (GA)9C, (CA)9G, (CTC)6G, (GTG)6C, and (ACC)6G. A total of 63 or 71.6 % of the 88 ISSR-PCR amplicons were polymorphic. The lowest value of polymorphic DNA fragments was recorded for (ACC)6G (59.1 %) and the highest for (GTG)6C (83.3%) primers. The number of rare alleles, which indicates the originality and homogeneity of the given population, in the experimental group were: (CTC)6G and (GTG)6C. From the analysis of the material obtained during the experimental research, it was possible to decode the genetic formula and barcode of the Armenian Mouflon, which can be used as a test to clarify the identification, origin, and evolution of the species and conduct molecular selection in the breeding processes.

2024
Dashtoyan, A.L. | Petrosyan, A.A.
A salting and ripening process is one of the main and most important steps in producing meat products, especially ground-dried and smoked ones, which undergo complex biochemical and microbiological processes and generate low molecular compounds. This ensures the quality and energy value of a finished product. The development of new methods is therefore necessary to accelerate the ripening process and improve the product›s useful properties. This study aims to develop an optimal dosage of rose hip extract that will accelerate and regulate the ripening process and saturate the high levels of vitamin C in the final product. Maturation was carried out under the same thermal conditions, the duration of maturation was determined by pH. The change in vitamin C content in salted semi-finished meat products was also determined. The research results were compared with the technical regulation of Customs Union Technical Regulations 034/2013 “Safety of meat and meat products”. By introducing this technology in the production of meat products, we will increase the shelf life of the finished product, reducing costs by reducing production costs.

2024
Hovhannisyan, Tigran | Efendyan, Paruyr | Khudaverdyan, Nane
Armenia, with its entire territory, is considered the most sensitive country to climate change. The land tax rate for agricultural lands is determined at 15 percent of the estimated net income determined by their cadastral assessment. The cadastral assessment of agricultural lands in the Republic of Armenia was carried out in 2002-2004. During the assessment, the materials of land management, soil science, geobotanical, and other studies and research conducted in the 1970-1980s were taken as a basis. The article presents the results of research and analysis conducted by the authors during 2020-2023, on the impact of climate risks on the yield and quality of crops on agricultural lands in the Republic of Armenia. As a result of the research, it turns out that among climate risks, the greatest damage to agricultural lands in the Republic of Armenia is caused by frost, hail, and drought, which affects the quantity and quality of crops from agricultural lands, and consequently the income received, which, however, does not reduce the tax burden of the landowner. As a result of the research, to modernize the assessment methodology in the process of calculating net income, it is recommended to adopt the revised calculation method developed and proposed by the authors using risk reduction coefficients (climate risks).

Bakhshetsyan, Shahane | Gevorgyan, Elyanora | Mikayelyan, Mikayel
Honey wine, also known as a fermented beverage made from natural honey, is believed to be one of the earliest alcoholic drinks created by ancient humans thousands of years ago, long before the discovery of grape wine. Our research aims to produce wine from honey collected in the Armenian mountains. A series of articles dedicated to the study of the possibility of obtaining alcoholic beverages made by fermenting natural honey (honey wine) using different types of dry active yeast and yeast autolysis derivatives. The data obtained from the research results will be interesting from both the scientific and production points of view. This will allow us to conclude that the selected yeasts can be used for producing such alcoholic beverages.

2024
Piatrouski, Sergey | Hlebus, Natali
The role of lipid peroxidation in the pathogenesis of liver diseases in sows was studied. The state of the antioxidant system in these diseases was also assessed. The liver of sows has been examined after slaughter. There were four groups formed: healthy, acute and chronic hepatosis (HS), and liver cirrhosis. An increase in the level of endogenous intoxication has established, the content of primary (diene conjugates), secondary (malondialdehyde, ketodienes, ketotrienes), and final (Schiff base) products of lipid peroxidation in the blood of sows with hepatopathy. Also noticed that sows with hepatopathy had decreased antioxidant protection, catalase activity, and concentration of tocopherol and ascorbic acid. The level of change was growing with a gravity of hepatopathy. The most expressed disturbance has been observed in sows with liver cirrhosis.

2023
Aleksanyan, V.S. | Matinyan, A.G. | Shirokov, S.N. | Trushkina, I.R.
Food security of the population is one of the main challenges of the 21st century, which, due to the events of recent years (Artsakh war, pandemic, Russian-Ukrainian conflict, sanctions, export restrictions) and their consequences, has become more acute. The stability of the grain sector in the country is of particular importance from the point of view of improving the food security in Armenia. Based on the study of international practice of state support for agricultural production, the results of analysis on the effectiveness of the state support tools traditionally used in different countries, as well as evaluating the state support for the development of grain production in RA, we have developed a model of state regulation of grain production, where the application of a number of realistic methods and measures is emphasized. The results of the studies document that, despite the government’s efforts to expand grain production, the grain sown areas are decreasing year by year, yield growth is not ensured, and the total growth is decreasing. Studying the international experience of state support for agricultural production, analyzing the results of the effectiveness of the state support tools traditionally used in different countries, as well as evaluating the state support for the development of grain production in RA for 2010-2021, we propose to revise the state regulation tools. In particular, to create a grain commission, form a guarantee and collateral price institute, set grain production and distribution quantities, strengthen contractual relations, form a commodity credit company and a grain price stabilization fund, apply commodity intervention, as well as promote economy-infrastructure intervention. We believe that the mentioned fundamental measures will contribute to the prospective development of grain production, ensure realistic results in the medium term, strengthen the cooperation between the state, production and science, as well as increase the self-sufficiency level of grain and, most importantly, will contribute to ensuring the food security of the Republic of Armenia.
