    Nanotechnology offers transformative potential in agriculture and horticulture, revolutionizing crop production, plant health, and resource management. Its dynamic influence is particularly evident in enhancing vegetable yields through targeted nutrient delivery. Nanofertilizers, which utilize nanoparticles with higher surface tension than conventional fertilizers, provide plants with slow-release, efficient nutrient availability. This improves nutrient uptake, reduces waste, and promotes more sustainable farming practices. Nanofertilizers are specifically designed to optimize plant growth, fertility, and pollination in flowers, resulting in higher yields and improved quality in horticultural crops. By enhancing the availability and use efficiency of nutrients, nano fertilizers reduce nutrient fixation and enhance overall productivity. This review focuses on the significance of nanotechnology development, nanomaterials, and nano fertilizers, highlighting their potential to improve productivity and quality in horticultural crops. It also explores how nanoparticles can enhance plant resilience, particularly in response to environmental changes, supporting food security for the growing global population. By providing targeted, efficient solutions, nanotechnology offers promising strategies for ensuring the long-term sustainability and health of horticultural production systems. The application of nanofertilizers in enhancing both crop quality and environmental sustainability positions nanotechnology as a key innovation for the future of agriculture.

    Grapevine (Vitis vinifera L.) is one of the most economically important productive drought stress-adapted crops grown globally. Fertilization is an important agrotechnical measure, where by applying optimal doses and types of fertilizers in an appropriate period, it is possible to significantly influence the development of the grapevine, and thus the production of high-quality grapes. This research aimed to determine the influence of soil and foliar fertilizing on the chemical composition of the clusters and the resistance of the clusters to low winter temperatures of grapevine cultivar ‘Cardinal’ grown in the Tikves vineyard area, North Macedonia. In November, with the basic cultivation of the soil, the fertilizer NPK 10-20-30 was applied (500 kg∙ha-1). Foliar fertilizing was performed with 0.4%, 0.8%, 1.2% and 1.5% solution of NPK fertilizer 18-9-27+2MgO + ME (1000 mg∙kg-1Fe; 200 mg∙kg-1 B; 150 mg∙kg-1 Zn; 500 mg∙kg-1 Mn; 56 mg∙kg-1 Mo; 110 mg∙kg-1 Cu). Different concentrations of foliar fertilizing had a positive influence on the chemical composition of the clusters and the resistance of the oaks to winter temperatures in which a significantly higher (p<0.05) content at all tested temperatures in all variants was obtained compared to the control area. In the clusters of the ‘Cardinal’ cultivar, higher (p<0.05) content of nitrogen (0.98%), phosphorus (0.98%) and potassium (1.03%), as well as the lowest percentage of frozen buds (6.05%) at a temperature of –15 °C, 8.85 % frozen buds at a temperature of –18 °C and 18.10% frozen buds at a temperature of –21 °C was determined at the variant 4 (NPK 10-20-30 + 1.2% solution of NPK 18-9-27+2MgO+ME). The highest content of calcium (1.73%) and magnesium (0.51%) in the clusters was determined in the variant 3 (NPK 10-20-30 + 0.8% solution of NPK 18-9-27+2MgO+ME).
