| Abstract | ||||
| SUMMARY This study was carried out during 2020 and 2021 seasons for examining the effect of single and combined applications of three plant extracts namely green tea extract, turmeric extract and garlic extract each at 0.05, 0.1 and 0.2% on yield and quality of Flame seedless grapes. Single and combined applications of the three plant extracts was very effective in improving some vegetative growth characteristics, vine nutritional status, yield and berry quality over the check treatment. The best plant extract in this respect was garlic extract followed by turmeric extract and green tea extract occupied the last position. Combined applications of these three plant extracts was materially favorable than using each plant extract alone in promoting these characteristics as well as the stimulation was proportional to increase in concentrations from 0.05 to 0.2% for promoting yield and berry quality of Flame seedless grapevines grown under sandy soil, it is advised to spray the grapevines three times at growth start, just after berry setting and one month later with a mixture of green tea extract, turmeric extract and garlic extract each at 0.1%. | ||||
