Abstract
During the 2021 and 2022 seasons, this research was conducted in the Balat area of Afaq Farm, located in the New Valley Governorate. Evaluating the timing and location of pruning and its effect on the growth and fruiting of Naomi mango trees. The experiment was carried out in a completely randomized block design with seven treatments and using three replicates, with two trees for each treatment. The current results are as follows: Shoot length, leaf area, total chlorophyll, shoot length, fruit set, and fruit set were significantly increased due to above- or below-bud pruning in March, May, or August compared to unpruned trees (check treatment). Pruning in May or August is generally better than in March. In addition, pruning under the buds at any time is better than pruning above the buds. There were no significant differences in most of the studied traits between the use of pruning in the months of May and August. In addition, the use of no previous treatments increased productivity and improved fruit quality compared to unpruned trees. In general, pruning trees in May above or below the bud gave the highest values for these studied traits. All pruning operations led to a significant improvement in the chemical components of fruit juice in terms of higher values of total and reducing sugars and total soluble solids and a significant decrease in total acidity compared to the control treatment. The results obtained indicated a noticeable improvement in vegetative growth and fruiting characteristics because of pruning Naomi mango trees during the months of May and August, much less than buds.
