| Abstract | ||||
| The present investigation was conducted during consecutive seasons (2022 and 2023) on 5-year-old “Aggizi Shame” and “Manzanillo” olive trees, which were planted at 6 x 5 m in sandy soil in a private orchard on Western Asuit Road, El-Menia Governorate, Egypt. The study focused on the effect of different seasonal or fruiting pruning models on vegetative growth, flowering characteristics, yield, fruit physical parameters, and the percentage of oil content in the olive trees. Most pruning models coincided in their timing of flowering at the beginning and end of the two studied seasons in Aggizi shame and Manzanillo cvs., except the free vase model, which was slightly later in Aggizi shame and Manzanillo, and introduced the shortest flowering period. The free vase model recorded the best values for vegetative growth parameters and physical fruit characteristics, followed by the modified spherical model, which demonstrated the superiority in fruit set, yield, and oil percentage, particularly in the Manzanillo cultivar. As a result, we recommend the modified spherical model, which combines the benefits of the free vase model, where light is relatively available to the interior shoots, and the spherical model, which protects buds and flowers when temperatures rise, particularly in olive-growing areas, which suffer from high temperatures | ||||
