| Abstract | ||||
| This study was carried out during 2022 and 2023 seasons to examine the effect of spraying nano- potassium and/ or lemon grass oil, each at 0.05 to 0.2% on yield and quality of berries of Flame seedless grapevines. There was a remarkable and gradual promotion on yield expressed in weight (kg.) and number of clusters per vine as well as weight, length and width of cluster due to increasing concentrations from 0.05 to 0.2% of each nano potassium and lemon grass oil in combination rather than untreated vines. Subjecting the vines to nano- potassium and/ or lemon grass oil had beneficial effect on improving quality of berries in terms of increasing berry colorations% in the cluster, berry weight and dimensions, TSS%, total sugars, % and reducing percentage of titratable acidity over the check treatment. The promotion was related to the increase in the concentrations of non- potassium and lemon grass oil. Therefore, it is necessary to use a mixture of nano- potassium and lemon grass oil each at 0.2% three times (growth start, just after berry setting and one month later) for improving yield quantitatively and qualitatively of Flame seedless grapevines grown under Middle Egypt conditions. | ||||
