The phonological characteristics at the beginning and the end of flowering and maturity , the characteristics of the fruits , weight of the fruits and the small fruits,  the juiciness ratio , acidity and the percentage of soluble solids and sugars in addition to the tree productivity.The results indicated that fertilization  with mineral and organic. Fertilizers surpassed the control  with significant differences in most  tree characteristics .Fertilizer treatment with vegetable compost showed the highest  productivity of the pomegranate tree which amounted to  42.a kg , with the highest values of the fruit characteristics ( weight of fruits was 554.3 g  , juiciness  ratio was 71.3%  , weight was 204.3 ml , ratio of soluble solids was 16.7%  , sugar ratio was 6.1% ) compared to the control where it was respectively .
