الملخص EN

The present study was conducted at the Farm of Faculty of Agriculture of Dohuk University on olive young trees (Olea europaea L) 4 years old, the trees were sprayed two times during the growing season 2014 first, 2 week after growth beginning and second, month after one with three concentrations of Algamix (0, 5 and 10 ml.L-1 ) and three concentrations of iron Fe2(SO4)3.H2O (0, 150 and 300 ml.L-1) in order to study their effect on growth, nutritional status of olive tree cv.

Arbegonia.

Results indicate that foliar spray of Algamix at 10 ml.L-1 and Fe at 300 ml.L-1 significantly increased all vegetative growth characteristics (leaf area, Total leaf chlorophyll, leaf dry matter and protein in leaves) and leave nutritional status (N, P and K) .

The interaction between 10 ml.L-1 Algamix and 300 ml.L-1 Fe tended to be more effective from other interactions in increasing all traits undertaken in this study.
