Nanomaterials possess unique features and their properties differ significantly from bulk material. This is mainly due to their nano- size which renders them high surface energy, large surface area, and spatial confinement. These properties do not usually occur in a bulk material. The size and surface area of any material determine how it interacts with any biological system. The decrease in size of the material increases the surface area and enhances its ability to react with any surface with which it comes into contact [1]. It has been observed that the efficiency of various biological systems depends on the size of the material. Because of the above- mentioned properties, the nanomaterial is currently employed in heavy- metal remediation, electronics, gene therapy, drug delivery, tissue culture engineering, crop bio- fortification, and crop protection [2, 3]. Nanobiotechnology provides a promising contribution to agriculture which could lead to new ways to overcome the various problems of the agriculture sector. Keeping in mind the magnificent properties of nanomaterials, plant researchers are using them as nano- fertilizers for crop protection and production. Green nanotechnology has revolutionized the agriculture sector all around the world. Meanwhile, the different concentrations of nanomaterial- based nano- fertilizers have been having
