Nanotechnology has come a long way showing major contribution in the field of agriculture and food production. The use of nanoparticles (NPs) is increasing day by day since they possess better solubility, enhanced magnetic and
optical properties, and better surface to charge ratio. The affirmative effects due to use of NPs has been explained including enhanced germination, increased root and shoot length, and overall increase in plant biomass along with improvement
in physiological parameters like photosynthetic activity. Recently, toxicological effects of NPs in agriculture have become
matter of concern. The current review focuses on the generation of reactive oxygen species (ROS), oxidative damage and
defense mechanism in response to phytotoxicity caused by the use of NPs. The other aspects included in this review include the effect of NPs on macromolecule concentration, plant hormones and crop quality. The review also discusses
about the future prospects of NPs on plant phytotoxicity and growth. Further, it also discusses about the possible measures
which can be taken for plant protection and growth while using NPs in agriculture.
