| Abstract | ||
| Experiments were conducted during two consecutive seasons of 2022 and 2023 on Ruby seedless grape cultivar grown in the experimental orchard of Pomology Department, Faculty of Agriculture, Assiut University. The following applications were carried out on each vine: Nano Zinc oxide at 5 ppm, Nano Zinc oxide at 10 ppm, Methionine at 50 ppm, Methionine at 100 ppm, Fish extract at 0.5 ml/L, and Fish extract at 1.5 ml/L The study confirmed that foliar spraying with nano-zinc and amino acids gave significant differences compared to the control in shoot length (cm), number of leaves / branch, and leaf area (cm2) in addition to increasing yield and improving the characteristics of bunches and berries. The study also confirmed improvement of the chemical properties of fruits, such as the ratio of total soluble solids, total acidity, and the ratio of total soluble solids to total acidity. The contents of sugars and anthocyanins also increased compared to the control treatment when foliar spraying with nano-zinc, methionine, and fish oil. | ||
