      3.3.2.2 Effects of Zn NPs Used in Agar Media and Hydroponic Application

      Zn NPs can promote early plant growth through agar media or hydroponic applications. Ramesh et al. (2014) found a substantial increase in chlorophyll and protein content in wheat through agar application of ZnO NPs (20–50 nm) between 250 and 2000 mg/L with minimal or no toxic effects. Mung bean and chickpea are grown in agar media at 20 and 1 mg/L, showed an increase of root length, root biomass, shoot length, and shoot biomass by 42 and 53%, 41 and 37%, 98 and 6%, and 76
