| Abstract | ||
| Nanotechnology is currently being employed extensively in horticulture. Enhancing production and fruit quality could be achieved by using nano fertilizers. The current study was conducted on Thompson Seedless grapevines planted on clay loam soil in a field experiment in the Pomology Department Research orchard, Faculty of Agriculture, Assiut University, Egypt, throughout the two consecutive seasons of 2022 and 2023. The study examined the effect of mineral fertilizers versus nano-fertilizers foliar application on yield and berry quality. Vines were sprayed with zinc (250 and 500 ppm), nano zinc (25 and 50 ppm), boron (2000 and 3000 ppm), nano boron (1000 and 1500 ppm), micronutrients (450 and 1000 ppm), nano micronutrients (450 and 1000 ppm), and distilled water (control). During the two seasons under study, the foliar application of all treatments to grapevines significantly improved yield and chemical characteristics of berries as compared to the control. On the other hand, spraying nano zinc at 50 ppm resulted in maximum yield, cluster weight, total soluble solids percentage (TSS %), TSS/TA ratio, and reducing sugars, as well as the minimum acidity juice (TA). Hence, the application of nano foliar fertilizers is crucial for improving the productivity and berry quality of the Thompson Seedless grape cultivar under the climatic conditions of Assiut Governorate. | ||
