The aim of this research paper is to investigate the impact of titanium oxide nanoparticles (TiO2 NPs) on germination of Capsicum annum (Pusa Sadabahar). TiO2 Nps were prepared using Fusarium oxysporum extract and then characterized through UV- visible spectroscopy, FTIR, XRD and SEM which confirms that nanoparticles were elongated spherical with 15nm diameter. Various concentration (100-500µg/ml) of TiO2 NPs were used to study different aspects of nanoparticles on Capsicum annum. The result emphasizes the positive effects of TiO2 nanoparticles up to the concentration of 400µg/ml on germination percentage and other morpho-physical parameters such as radical length, plumule length, fresh and dry weight, total seedling length as compared with non-treated plants. Overall we found better results of using biologically synthesized NPs in chilli plants, while the significant decrease in outcome was also observed at higher concentration.
