Nanotechnology, as the source of new industrial materials, has been widely used in recent years and has appeared in almost every field. Nowadays, nanoparticles are used in many areas like textiles, cosmetics, pharmaceuticals, automotive and defense (military) industries. The usage of nanoparticles has increased in recent years, but their effects on the environment are not exactly known. In this study, TiO2 nanoparticle (TiO2-NP) was applied at increasing concentrations (0, 5, 10 and 20 mg L-1) to maize (Zea mays L.) plant grown in hydroponic culture at 16 h light/8 h dark, 25/20 degrees C temperature, 60% humidity and 10 Klux light intensity for 20 days. Application of TiO2 -NP on biomass production, nitrogen (N), phosphorus (P), potassium (K), zinc (Zn), iron (Fe), manganese (Mn), copper (Cu) and chlorophyll contents were investigated. The results showed that the plants' shoot and root biomass and leaf chlorophyll contents were significantly reduced with increasing TiO2-NP applications. On the other hand, TiO2-NP applications positively affected macro- (N, P, K) and micronutrients' (Zn, Mn, Cu) concentration except for Fe. Compared to the control treatment, the concentration of Zn, Mn, Cu, N and P significantly increased with the application of TiO2 nanoparticles. Consequently, TiO2-NPs treatments have increased nutrient uptake of maize excluding iron while decreased the dry biomass of maize at high doses.
