The current study assesses the effects of utilizing Bacillus subtilis, Rhizobium bacteria, and Arbuscular mycorrhizal fungus as a biofertilizer on apricot sapling cultivar Bayaa. Concurrently, the use of to promote plant growth was developed. Furthermore, three factors were used. The first component was added for soil apricot sapling by dilution suspension of Bacillus subtilis with three levels (0, 100, 200 ml.L-1) while the second factor was added by dilution suspension of Rhizobium spp. with two levels (0, 200 ml.L-1) and third factor was dilution suspension add Arbuscular mycorrhizal fungus with three levels (0, 10, 20 ml.L-1). The results demonstrate that adding Bacillus subtilis bacteria to the soil of apricot saplings at both levels (100, 200 ml.L-1) had a significant influence on the leaf area, total chlorophyll, N%,P%,Mg%, and reduced proline and peroxidase. The effects of Rhizobium bacteria at level (200 ml.L-1) on all trails under study were comparable to non-addition of Bacillus subtilis .Arbuscular mycorrhizal fungus of the treated saplings at both levels (10 and 20 ml.L-1) to the soil of apricot saplings had a significant effects on the leaf area, the increase in the heigh,total chlorophyll ,N%,P%,Mg% and reduce proline and peroxidase. The interaction among Bacillus subtilis, Rhizobium bacteria, and Arbuscular mycorrhizal fungi were effects on trails under study especially (20 ml.L-1Arbuscular mycorrhizal +200 ml.L-1 Rhizobium + 200 ml.L-1 Bacillus subtilis) treatment, it was high significant in all trails.
