Effect of Girdling and Potassium Fertilization on Yield Efficiency and Fruit Quality of Apricot cv. Amal
The present investigation has been carried out at El-Kanater Horticultural Research Station during both 2015 and 2016 seasons to study the effect of four levels of potassium soil applied either alone or combined with girdling treatment on some fruiting parameters and both fruit physical and chemical properties as well as leaf nutrient status of Amal apricot trees budded on Okinawa rootstock.Obtained data showed that, the investigated fruiting parameters (fruit set % and yield either kgs/tree or ton/feddan) were significantly increased with increasing the levels of K and girdled trees when compared to the control treatment. Moreover, fruit properties including both fruit physical characteristics i.e., fruit weight, volume, firmness, height, diameter and fruit shape index as well as fruit chemical properties (TSS %, acidity % and TSS/acid ratio) were significantly improved as a result of the highest soil application level of K and girdled trees as compared with the control trees. In addition to that, leaf nutrient content of some macro-elements (N, P and K) were improved by the different investigated combination treatments under study from the standpoint of statistic during both 2015 and 2016 seasons. Generally, it could be conclude that, most of investigated combination treatments of (K x G) resulted in a positive and a significant effect on all fruiting parameters, leaf nutrient contents and most fruit quality of Amal apricot fruit trees. Furthermore, the treatment of K at 1500 gm/tree x girdling gave the best and the most effective combination treatment for increasing fruiting parameters and improving both the most physical and chemical properties and leaf nutrient contents of Amal apricot trees cultivated under condition of Qalyubeia Governorate.
