A pot experiment was carried out on the research field of the department of Biological Sciences with five treatments using varying quantities of graphene nanoparticles (500 ppm and 1000 ppm) and TiO 2 nanoparticles (25 ppm, 50 ppm and 100 ppm) along with a control. The experiment was planned using four replications. The layout used was complete randomized block design. Purpose of the study was to analyse biochemical characteristics of okra under the varied nanoparticle treatments. The experiment stated that the graphene and TiO 2 nanoparticles were advantageous to okra crop in terms of yield. Among the treatments, 100 ppm of TiO 2 nanoparticles were found to be favouring the biochemical and yield parameters in both the varieties of okra. As compare to the STAR-77 variety NAYAN-11 showed better performance in respect to biochemical characteristics and yield. Keywords: Graphene; TiO 2 ; biochemical parameters; okra.
