This study was conducted in the lathhouse of the Department of Plant Production Techniques / Musayyib Technical College during the period from 1/9/2021 to 1/6/2022 to study the effect of biofertilization and spraying with nano-fertilizer and gibberellin on the growth of Aloe vera plants. The experiment included three factors, three levels of biofertilization (without addition, azotobacter, mycorrhiza) and their symbols (E0, E1, E2) respectively, and spraying with nano iron fertilizer in three concentrations (0, 1500, 3000) mg L-1 and symbolizing them (Fe0, Fe1, Fe2) respectively, and gibberellin in three concentrations (0, 150, 300) mg L-1 and symbolizing them (G0, G1, and G2).The experiment was conducted as a factorial experiment according to Randomized Complete Blocks Design (R.C.B.D) with three replications and the averages were compared according to the least significant difference (L.S.D) test under the 5% probability level, and the results were as follows: The treatments of the addition of azotobacter and spraying with nano iron concentration of 3000 mg L-1 and gibberellin concentration of 300 mg L-1 were significantly excelled in all studied traits. It also caused the bi-interaction (mycorrhizal + nano iron 3000 mg L-1), (Mycorrhizae + gibberellin 300 mg L-1) and (Nano iron 3000 mg L-1 + gibberellin 300 mg L-1) and the triple interaction between the study factors (mycorrhizalgia + nano iron 3000 mg L-1 + gibberellin 300 mg L-1) was a significant increase in most of the studied traits.
