Sunflower is one of the most prominent oil seed production source around the world. Especially in the shadow of global warming and rapid population growth, the demand for its use will increasingly continue due to its tolerance to different environmental conditions, including drought. Although Turkey is one of the leading countries in sunflower cultivation, it still imports a significant amount of sunflower oil to meet the local demand. However, increasing the yield in crop production is possible via environmentally friendly alternatives. In many studies, nanoparticle treatment with appropriate dosages instead of pesticide and chemical fertilizer utilization, have been proved to positively affect the plant growth and crop yield. Furthermore, these nanoparticles can be synthesized via green synthesis by using plant leaves as natural reducing agents. Fe and Zn are essential elements for plants having several roles in vital metabolic activities such as respiration, photosynthesis, chlorophyll and auxin synthesis etc. Although Ti has not an essential role in plants, there are many study indicating that TiO2 nanoparticles improve seed germination, resistance to biotic stress factors and crop yield in several plants. In the light of all this information, in this study, plant mediated green synthesis of Iron Oxide(Fe3O4), Zinc Oxide(ZnO) and Titanium Dioxide(TiO2) nanoparticles by using Laurus nobilis leaves was performed to investigate their effect on local sunflower species. Dynamic light scattering (DLS) analysis and Transmission electron microscopy (TEM) images revealed that nanoparticles with varying size distribution between 5-200 nm were successfully synthesized. After that, the effects of nanoparticles on growth parameters of sunflower plants were examined in hydroponic conditions. Plant groups treated with 1 - 5 ppm Fe3O4 nanoparticles gave higher values in terms of average root length, fresh weight, number of leaves and leave surface area compare to others and the control group.
