Our study explored the compatibility of Bio-ZnO NPs foliar spray as micronutrient fertilizer and its role in addressing the Cd accumulation in contaminated soil. We found the sweet potato leaf extract was found to play an important role as stabilizing and capping agent for the green synthesis of ZnO NPs. These green synthesized ZnO NPs were found effective in supplying Zn to lettuce via foliar application. ZnO NPs supplementation through foliage had positive effects on crop growth in Cd contaminated soil and negatively affected shoot Cd content. To comprehend the mechanism of reduced Cd in shoots due to foliar application of ZnO NPs, detailed research on the transport and fixation of these metals in plant systems is required. In addition, future research will look into the effects of ZnO NPs foliar application on root Cd uptake and the relationship between root and shoot Cd and Zn accumulations.

What was accomplished under these goals?
We have initiated the research program including hiring both graduate and undergrad students and setting up the lab and greenhouse. Two sets of critical experiments have been done: 1) nanoparticle synthesis and 2) nanoparticle interaction with plants (lettuce and sweet potato). We have one conference presentation about the effect of synthesized nanoparticles used for seed priming. We also have submitted a book chapter about the effect of nanoparticles on plants.
