The presence of nanoparticles in the medium and the possibility of their absorption and displacement by the plants is the motive of this research. Graphene oxide carbon nanotube is one of the most important members of the Graphene family. In recent years, the effect of these nanotubes on food products has been studied by researchers. In this research, seeds of soybean variety Koars were evaluated at 6 levels (0, 100, 200, 400, 800, 1600 mg/L) of Graphene oxide nanoparticles in a completely randomized design with three replications. Microscopic examinations revealed the presence of these nanoparticles in the skin of the seeds and in the seedlings in the epidermis and the outer layers of the root hair. Incremental growth parameters were observed including root length, fresh weight and root dry weight under 400mg/l treatment. These findings can help improve the quality of fertilizers using nanoparticles
