The migration of young people from rural to urban areas poses a significant challenge to the sustainable development of rural communities in North Macedonia, leading to an aging population and diminished natural growth. This trend exacerbates socioeconomic inequalities, fostering social insecurity and the exclusion of rural youth. The far-reaching consequences of this migration influence both urban and rural landscapes across various developmental domains. To that end, this research aims to investigate the impact of main socioeconomic factors on rural youth migration. A survey of 550 rural residents aged 18-40 addressed was conducted using a tailored questionnaire. The data collection approach ensured nationwide diversity across all Macedonian planning regions, nationalities, genders and village types. Data processing involved the application of standard descriptive analysis and a binary logistic regression approach. Key findings show that factors such as gender, marital status, region, nationality, education, employment and having family agricultural holdings do not significantly impact rural youth migration. On the contrary, having children, household size, perceptions of employment opportunities, urban or rural lifestyle preferences and overall rating the quality of life in rural areas exhibit notable significance. These findings contribute to a greater understanding of the complexities surrounding rural youth migration. In conclusion, the logistic regression model serves as a powerful tool to pinpoint crucial factors influencing rural youth migration. These insights provide a solid foundation for shaping targeted policies, essential for retaining and supporting rural youth and fostering sustainable development in both urban and rural areas of North Macedonia.

Abstract In agricultural production, and in the specific case in viticulture production, the production of healthy food, that is the production of healthy plants and healthy and quality fruits, and especially the production of virus-free planting material, is still an actual problem. Global pollution has contributed to finding different innovative solutions in the production of healthy food and also in agricultural production and specifically in our trials in viticulture production, it is still very current of healthy and resistant plants and animals. In addition to the application of genetics and the selection of varieties, the choice of nutrition for the plant and the choice of soil improvers (part of the medium where the plant grows) are very significant in the problem. In particular, our investigations are aimed at improving the properties of the soil during the cultivation of rootstocks (mother plants) in viticulture production. The tests were carried out in the period 2017 - 2019, in the Skopje Vineyard. Grapevine rootstocks introduced in the Republic of North Macedonia were randomly selected. A significant segment in this treatment is that our "new formula" of the mineral zeolite, which is currently being tested in our laboratory, was used. This agent has proven to be very safe for use as a preparation for improving the properties of the soil, and also as an effective agent for protecting and improving the resistance of the grapevine rootstocks to diseases and pests. The treated plants had a better habit and better resistance to external conditions. This preparation is very suitable for use in organic production.

ABSTRACT Our studies included some autochthonous and regional grape varieties grown in the Republic of North Macedonia. The autochthonousvarieties were examined -White winter, Konchanka, Stanushina, Ohrid black and Ohrid white, and the regional varieties -Vranec, Prokupec, Smederevka, Zilavka and Zupljanka were examined.The tests were divided into three methodological units. The first method was applied to all varieties -data collection, history and comparison with other tests.The second method was performed on all varieties -ampelographic identification because we had samples from all varieties. In some of the varieties, the third method was performed, that is, genetic (DNA) identification was made in the period from 2010 to 2020 in different examination centers and at different times. The results are compared with the results of a study by Professor M. Aradhya of the USDA Research Center, Davis CA, USA. He has performed a wide range of genetic identification on a number of autochthonous varieties in Europe and Asia, including varieties in the Balkans.With the second method of examination -ampelographic identification according to O.I.V. descriptors we got the most realistic results. An ampelographic description of certain characteristics of the individual organs of the vine was performed and it was concluded that the varieties according to their anatomical and physiological characteristics belong to 2 groups: ecological-geographical group Black Sea varieties, subgroup Balcanica and ecological-geographical group Eastern varieties, subgroup Antasiatica.

ABSTRACTThis paper describes the experiments performed on the Muscat Hamburg variety in the Skopje vineyard. Initial examinations were made in 2013-2014 in the collection plantations of the Agricultural Institute where the Muscat Hamburg variety was grown. In the then plantation were found 3 individual grapevines(units)in which differences in morphological and physiological characteristics were identified.Such grapevines are marked as individuals, monitored and taken from them for propagation material (they are vegetatively propagated by individual producers, and the seeds are used for laboratory tests). In fact, the phenotypic variability of the variety was monitored. In the following years, from 2013-2019, phenotypic variations were observed in other individualplantations and individual grapevines in the conditions of the Skopje vineyard.Most of the changes in the individual units of the Muscat Hamburg variety are manifested in the bunch, grain, fertilization, phenology, frost resistance and some technologicalcharacteristics. For example, in these units the grape is more compact, with better fertilization, darker color, the phenological feature of maturation takes place earlier and so on. Freezing resistance of these units is higher.They have the potential for better technological characteristics that would be used further for better product quality -wine, spirits and more.These units are the basis for obtaining improved properties in clonal selection and hybridization.

Abstract In R.N. Macedonia has a large number of autochthonous or domestic varieties (cultivars) of grapevine that are grown as individual vines or in small, limited plantations. Until the beginning of the 20th century and before the phylloxera attack in our country, native varieties were much more represented. Autochthonous varieties existed and were cultivated for a long time in several vineyards and were characterized by stable and significant properties. These varieties are adapted to the environmental conditions where they are grown and are carriers of stable genes that can be used in further selection and hybridization to obtain new grape varieties. Therefore, it is very important for a country (region) to have autochthonous varieties in its assortment.In this paper, we considered four autochthonous grape varieties - two table varieties (Konchanka and white winter) and two wine varieties (Ohrid white, Ohrid black). We tried, according to the ampelographic description and certain characteristics of the reproductive system, to determine their origin. According to the phenotypic characteristics that refer to the centers of origin of the varieties, the studied varieties - Konchanka and White winter belong to the Eastern varieties convarietas orientalis, subconvarietas antasiatica, and the studied varieties Ohrid white and Ohrid black variety belong to the Black Sea - Balkan varieties convarietas. pontica, subconvarietas balcanica. Among the examined varieties, the properties from the second group of descriptors are described in detail according to the proposals of O.I.V. According to some codes (characteristics) there is a big difference between varieties. Also, for a more detailed differentiation of the varieties, cytological properties were examined - pollen germination and vitality, number of chromosomes in mitosis and meiosis, ploidy level, percentage of fertilization (fecundation), self-fertilization (autogamy) and cross-fertilization (xenogamy). The statistical processing of the ampelography data is according to a cluster program (SPSS) that works on the binary similarity or dissimilarity as measures used to group the data and further form a clear dendogram display.

Aromatic profile of Macedonian and Bulgarian red wines from local variety Vranec and hybrid variety Kaylashki Rubin
(2022)
Dimitar Dimitrov; Dushko Nedelkovski
Introduction. The aim of the present study was to define the aromatic profile of Bulgarian and Macedonian red wines obtained from the local variety Vranec and the hybrid variety Kaylashki Rubin. Materials and methods. Gas chromatographic (GC MS) study to define the aromatic profile of red wines from the local variety Vranec (grown in the Republic of Macedonia) and the hybrid variety Kaylashki Rubin (grown in the Republic of Bulgaria) was conducted. Results and discussion. 1-pentanol was dominated in the fraction of higher alcohols in both wines. Other aroma compounds identified were 1-propanol, 2-propanol, 1- butanol, 1-hexanol, and 3-methylthio -1-propanol. The wine of the Vranec variety showed greater complexity in terms of this fraction, as in it 3-hexen-1-ol was identified, which was not present in the wine of Kaylashki Rubin. High amount of the aromatic alcohol – phenylethanol – was identified in both wines. This compound had great importance for their floral aroma. The ester fraction of the two wines was diverse, represented by isopentyl acetate, ethyl caprylate, ethyl hexanoate, ethyl decanoate and diethyl malate. The Vranec wine showed greater ester complexity, as in it two more ester representatives were identified – ethyl-2-hydrobutyrate and 2-hydroxy-3-methyl-diethyl ester. In both wines, one fatty acid was identified – heptanoic acid, in very low concentrations. According to the panelist both wines were very harmonious in their own way and had their typical notes as expected for the both varieties. In overall, the descriptive analyses confirmed the components determined by the GC MS and gave a clear view about the aroma profile of both varieties. Conclusions. Both wines showed a diverse, balanced aromatic profile, each of which, based on the peculiarities of its volatile composition. Meanwhile, each wine had individual aromatic properties.

Investigation of organoleptic characteristics and determination of some biochemical compounds content in the fruit of eight traditional pomegranate (Punica granatum L.) varieties and types: Lifanka, Bejnarija, Karamustafa, Ropkavac, Valandovska kisela, Lifanka clone, Zumnarija and Hicaz, from Valandovo area (North Macedonia), was performed. Fruit from Valandovska kisela and Hicaz varieties are characterized with the lowest value of pH and also with highest content of citric acid. The content of fructose sugar prevails over the content of glucose in 1,1 ratio. Anthocyans are the most common in fruits from Hicaz variety. The Valandovska kisela variety has the highest content of phenols. The fruits from Ropkavac and Zumnarija varieties have the highest content of flavan-3-ols which give them a characteristic flavor. According to organoleptic evaluation of external fruit appearance, the best ranked is the Karamustafa variety. According to the internal characteristics, i.e. the fruit aril, again stood out as the best the Karamustafa variety, by all parameters. The respondents are pointed out also Ropkavac and Bejnarija varieties in evaluation of aril flavor and aroma, such as very good varieties, especially by the aril juiciness. According to all organoleptic (external and internal) characteristics, the highest ranked is Karamustafa variety which is recommended as a perspective variety of pomegranate for spreading in R North Macedonia
