    The present study deals with ethnobotanical survey of wild vegetables used as food and medicines in North Macedonia. For obtaining information about traditional uses of wild vegetables in North Macedonia 84 respondents were interviewed using structural designed questionnaires, from March to June 2023. 78.6 % of respondents practiced picking wild vegetables, while 94 % of respondents consumed wild vegetables. Obtained results showed that the fourteen plant species from eleven botanical families were recorded as wild vegetables. Most of the mentioned wild vegetables belong to the Polygonaceae family. The botanical family, scientific name, folk name, used plant parts, culinary and medicinal use as well as the relative frequency of citation index (RFC) of wild vegetables are shown for each of the plant species. In this research, Urtica dioica L. is the species with the highest relative frequency of citation index (0.25). Also, it was found that among the edible parts, leaves are dominant (59 %). Ethnobоtanical studies are key to finding ways to use natural plant resources, and therefore such research should be continued in the future.

    Reducing chemical pesticide use and adopting biological alternatives are key priorities in sustainable horticulture. This study compared the effects of chemical and biological treatments on stomatal density in parsnip (Pastinaca sativa L.) and evaluated associated soil microbiological changes. Field trials near Skopje included a control (untreated) plot and three treatments: (T1) foliar application of Ridomil Gold MZ 68 WG (40 g/kg metalaxyl-M + 640 g/kg mancozeb), (T2) Bacillus velezensis strain B-98, and (T3) Bacillus amyloliquefaciens strain B-62. Stomatal density was determined microscopically on both leaf surfaces, and soil microbial communities were quantified before and after the growing season. ANOVA revealed highly significant differences (p < 0.001) in lower epidermal stomatal density between the control and all treatments, with T3 exhibiting the highest value (1552 stomata/mm²). Biological treatments also increased beneficial soil microorganisms, including nitrogen-fixing and cellulolytic bacteria. The results highlight B. amyloliquefaciens strain B-62 as a promising biopreparation for enhancing physiological traits and soil health in sustainable parsnip production.

    Ethnobotanical study on the use of Sideritis scardica Griseb. in North Macedonia
    (Faculty of Agronomy Čačak, 2025)

    ;
    About 350 wild medicinal species that exist in the territory of North Macedonia are used in traditional medicine. Apart from medicinal purposes, medicinal plants are also used for culinary and recreational purposes. Among the medicinal plant species, the endemic species Sideritis scardica Griseb., whose presence has been recorded in the Balkans, has a special place. History, tradition and oral transmission of medicinal recipes speak for the daily use of this plant since ancient times. Wanting to preserve the traditional knowledge of S. scardica Griseb. from oblivion, the purpose of this research is to document its use in everyday life, especially its traditional use. As part of this research, an ethnobotanical survey was conducted in the period from June to September 2024 in North Macedonia. One hundred respondents were included in the research, and the obtained results showed that the respondents are well acquainted with this plant. The folk name Mountain tea is the most commonly used in our country. This plant is mostly used in the form of tea for recreational purposes (80%), while only 20% for medicinal reasons. Percentage-wise, Mountain tea is mostly used for the treatment of colds, followed by urinary, digestive and respiratory problems. In our country, people prefer buying the plant to collecting it in nature. This research provides data on the traditional use of S. scardica Griseb. in North Macedonia, and hence suggests that, in order to avoid the loss of traditional knowledge, greater efforts are needed to preserve and record the knowledge of use, not only for this plant but also for other medicinal plants.

    Different types of fertilizers, such as chemical fertilizers, organic fertilizers and natural fertilizers are available on the market. The type of fertilizer has a large impact on the plant production quality. The aim of this study, which was conducted in field conditions in the village Jurumleri, near to Skopje, North Macedonia, was to investigate the influence of the application of two different types of fertilizers on leaf area and stomatal density in potato. The influence of microbiological fertilizer Slavol and organic fertilizer Biohumus was investigated. Also, a control plot without any fertilizer was used. A statistically tool (ANOVA test) was used for data analyses. From the results, it can be concluded that the statistically highly significant difference were found between average leaf area of plants treated with Slavol and plants treated with Biohumus (p<0.001). Also, statistically highly significant difference between plants treated with Slavol and control plants regarding total stomatal density was detected (p<0.001). Between plant treated with Slavol and plants treated with Biohumus was noticed statistically very significant difference (p<0.01). It can be concluded that the microbiological fertilizer Slavol showed better results than Biohumus in our research.
