Abstract
Three main factors arc believed to be responsible for considerable lecline in Manfalouty pomegranate production in Upper Egypt. Fruit racking, sunburn and pale color of fruit skin (discoloration) are serious hut disorders which render fruits unsuitable for the local market or for xporting.
Accordingly, three field experillldnts were carried out during three uccessive growing seasons of 1991, 1992 and 1993, in two pomegranate rchards. The first is located at the Experimental Station of Assiut University (clay soil) and the second is located at El-Ghorieb Experimental tation where the soil is sandy calcareous.
he first experiment:
The main objective of this trial is to minimize fruit cracking jhroughout certain treatments of soil application of ZnSO4 as follows: 1) ntreated control trees; 2) 400 g ZnSO4I tree/year applied on June; 3) 400 /tree/year on August; 4) 800 g/tree/year on June; 5) 800 g/tree/year on ugust. These treatments extended for 3 seasons. During 1992 and 1993 easons two additional treatments were applied either on clay or sandy alcareous soil. Such two treatments were; 1) soil application of 800 g nSO4/tree divided in two equal doses and applied on June and August, and 2) 1600 g/tree divided in two equal doses and applied on June and August.
flie second experiment:
The main objective is to minimize fruit cracking after leaving them xtra time on the tree after maturity waiting for best price. The treatments
