This study was carried out in a private orchard at AL- Abbasyia , Najaf Governorate during the growing of season 2015 on the local sours orange fruit .

The results indicated that spraying trees with treatments caused a significant increasing in the rate of leaf aria length of branches ,total chlorophyll , percentage of dry material , length, diameter , weight of fruit, percentage of juice , percentage of peel ,peel thickness , vitamin C Total soluble solids(T.S.S) , percentage of titratable acidity (TA) and percentage of T.S.S / TA .There was significant differences between these treatments .The treatments of concentration of Hletab 3 % gave the highest rate of vegetative and fruiting characteristics on the year of studied .
