The excessive use of nitrogen and phosphorous fertilizers led to environmental pollution and serious health issues. Nanotechnology may solve such a type of problems by providing nanomateriales of high performance. Here, we reviewed the beneficial effects of some different nanoparticles on the growth of different parts of different plants belongs to 14 different families. Nanoparticles such as CNT, Ag-NPs, TiO2-NPs, Au-NPs, S-NPs, Ag-NPs+ Magnetic field-NPs, ZnO-NPs, Fe-NPs, SiO2-NPs, RA-NPs, Zinc-NPs, Silica-NPs, Apatite-NPs, CeO2-NPs, Cu-NPs, CaCO3-NPs, Chitosan-NKP-NPs and Carbon nono-tube coated NKP+ Chitosan NPK-NPs show better growth enhancement effect on different parts of plants growth and crop production when used in proper concentration. We find that the most favorable effect of NPs was on, chlorophyll contents, root and shoot length followed by proteins contents and plant biomass.
