Title: INFLUENCE OF NANO FERTILIZATION ON THE CHEMICAL COMPOSITION AND BIOACTIVE COMPONENTS IN GRAPEVINE. Authors: Stojanova, Marina; Đukić, Dragutin; Stojanova, Monika; Kaya, Yalcin; Mandić, Leka Abstract: Nanofertilizers represent a major advancement in agriculture, offering enhanced nutrient transport and regulation, resulting in improved plant growth and crop yield. Essential nutrients such as nitrogen, phosphorus, potassium, and micronutrients are crucial for healthy plant development, and the application of nanofertilizers has demonstrated improved soil properties, better water retention, and increased plant resilience to stressors. This study investigated the effects of a newly developed organic nano NPK+Zn fertilizer on the nutrition of the ‘Cardinal’ grape variety, focusing on its influence on the chemical composition of grape leaves and the bioactive compound content in grape fruit. The experiment included four variants: 1. Control (untreated); 2. NPK mineral fertilizer (soil); 3. Nano NPK + Zn (3 g l-1 foliar); and 4. Nano NPK + Zn (5 g l-1 foliar). Treatments were applied four times during the vegetation period: 15 days before and after flowering, during grain growth, and at veraison. Results showed that Nano NPK fertilization led to a higher (p<0.05) concentration of key nutrients and bioactive compounds in both leaves and grape bunches compared to the control. Notably, the 3 g l-1 concentration of the Nano NPK + Zn foliar treatment yielded the highest (p<0.05) content in the examined parameters. While the findings indicate the promising potential of Nano NPK fertilization to enhance grapevine nutrition and fruit quality, further research is necessary to assess long-term effects on soil health, grapevine longevity, and the sustainability of agricultural practices. This approach may offer a more sustainable alternative to conventional fertilization methods.

PHYTO- AND PEDOBIONT YEASTS OF PLANTS

Title: PHYTO- AND PEDOBIONT YEASTS OF PLANTS Authors: Mandić, Leka; Bošković, Ivana; Stojanova, Monika; Stojanova, Marina; Đukić, Dragutin Abstract: This paper contributes to the study of yeast communities in the rhizo- and phyllosphere of plants, as these communities have not been sufficiently investigated in terms of the influence of various ecological factors and root exudates. The surface of the underground and aboveground parts of plants significantly differs in the composition of dominant epiphytic yeast species. Eurybiontic and phytobiontic yeasts dominate in the phyllosphere, while pedobiontic yeasts prevail in the rhizosphere. Seasonal changes in the abundance and qualitative composition of yeast communities in the rhizosphere are considerably more stable (synchronized) than those in the phyllosphere.

NITROGEN FIXATION IN THE GASTROINTESTINAL TRACT OF RODENTS

Title: NITROGEN FIXATION IN THE GASTROINTESTINAL TRACT OF RODENTS Authors: Đukić, Dragutin; Bošković, Ivana; Stojanova, Monika; Stojanova, Marina; Rankova, Zarija; Šarčević, Ljubica Abstract: This review paper presents a comprehensive overview of the presence of nitrogen-fixing activity in various parts of the digestive tract and intestinal content in the red-backed vole and the common vole. Research has shown that nitrogen fixation, the process of converting atmospheric nitrogen into forms available for biological use, does not occur uniformly across all segments of the digestive system. The highest level of nitrogen-fixing activity is observed in the wall of the large intestine, indicating the importance of this part of the gut as a site of intense microbial activity. In contrast, the lowest level of activity is recorded in the wall of the forestomach, likely due to unfavorable conditions for the development of nitrogen-fixing microorganisms in this part of the system. Furthermore, nitrogen-fixing activity in the contents of all intestinal segments in voles is significantly higher compared to control groups, confirming the presence and activity of a specific microbial community. These findings suggest that gut microorganisms in rodents play an important role in nitrogen supplementation, which may be crucial for the nutritional strategy of these animals, especially given the low nitrogen content of plant-based food sources. This paper contributes to a better understanding of microbiological and biological processes in the digestive tract of rodents and opens the way for further research in the field of their ecology and nutritional adaptation.

EXPLORING NANOFERTILIZERS: INNOVATIONS FOR PRECISION AGRICULTURE AND NUTRIENT MANAGEMENT

Title: EXPLORING NANOFERTILIZERS: INNOVATIONS FOR PRECISION AGRICULTURE AND NUTRIENT MANAGEMENT Authors: Stojanova, Monika; Đukić, Dragutin; Stojanova, Marina; Semenov, Aleksander; Lalević, Blazo Abstract: Nanofertilizers mark a significant breakthrough in agricultural practices, offering innovative solutions for nutrient transport and regulation from the soil to plants. Essential nutrients like nitrogen, phosphorus, potassium, sulfur, calcium, magnesium, manganese, copper, zinc, iron, and molybdenum promote healthy plant growth and ensure successful crop production. Fertilization has been a core agricultural practice since its origins, driven by the need to boost crop yield and quality. The advent of nanofertilizers introduces a transformative shift, paving the way for next-generation fertilizers. These advanced solutions are not only cost-efficient but also enhance soil's chemical and physical properties, such as improving water retention. Additionally, plants treated with nanofertilizers demonstrate increased yields, superior quality, and enhanced resilience to both biotic and abiotic stress factors. This review aims to underscore the significance of nanofertilizers in modern agricultural practices by comparing them with conventional fertilizers, emphasizing their advantages, their role in improving crop quality and productivity, and their potential contribution to environmental sustainability.
