Abstract
:  Citrus fruits have the majority importance of fruit crops in Egypt.  Limes come next to both of oranges and mandarin, whereas lime trees are grown mainly in new reclaimed sandy soils for favorite production and exportation potential.  This study was carried out during two seasons 2003 and 2004 on organically fertilized Egyptian lime trees grown in reclaimed sandy soil of the experimental station in El-Ghoraieb region, Faculty of Agriculture, Assiut University.  The objective of this investigation was to improve fruit quality of organically fertilized Egyptian lime trees by using both of GA3 (0, 5 or 10 ppm, sprayed 2 weeks after fruit set) and Nitropine (strains of nitrogen fixing bacteria) or Phosphorine (phosphate dissolving bacteria) at rate of 100 g/tree, each applied at fruit set.  The obtained results of this study showed that spraying GA3 alone and both of Nitropine or Phosphorine induced significant improvement of physical and chemical characteristics of mature fruit.  Phosphorine was more effective in improving fruit quality than Nitropine.  Moreover, the combination between GA3 (10 ppm) and Phosphorine gave the best results in this connection, specially for fruits that were harvested at the 3rd harvest date.  Therefore, it could be recommended to spraying GA3 (10 ppm) combined with 100 g of Phosphorine/tree to organically fertilized trees and fruits should be picked at the 3rd harvest date (at the 2nd or 3rd week of August) for improving fruit quality of Egyptian lime under the same conditions of this study.
