Bamboo Biochar and Zinc Oxide Nanoparticles Improved the Growth of Maize (Zea mays L.) and Decreased Cadmium Uptake in Cd-Contaminated Soil

Cadmium (Cd) has attained top priority among all the toxic trace elements, and it easily accumulates in human body through various pathways. The current pot study was focused on impacts of foliar spray zinc oxide nanoparticles (ZnO NPs) (0, 50, 75, 100 mg·L−1), alone or combined with soil-applied bamboo biochar (1.0% w/w), maize growth Cd Zn accumulations grains under Cd-contaminated soil. results showed that maize-growth, photosynthesis, gas-exchange attributes were accelerated by foliar-applied ZnO NPs, this effect further enhanced application combination NPs. All amendments decreased electrolyte leakage (EL) malondialdehyde (MDA) hydrogen peroxide (H2O2) contents, they activities antioxidant enzymes leaves roots more than control. concentrations shoots 74.55%, 66.38%, 76.19% after a mg·L−1 concluded NPs is feasible strategy for safely growing crops soils.
