Zinc biofortification and yield enhancement in rice with nano- primed seeds and foliar sprays.

ABSTRACT: Zinc deficiency in rice, a staple food consumed by more than half of the world's population, poses a major challenge to food safety and nutrition. In this study, the application of biosynthesized zinc oxide nanoparticles (ZnO NPs) was investigated as a sustainable strategy to solve this problem. The laboratory experiment on seed priming was conducted with four concentrations of ZnO nanoparticles (25, 50, 75 and 100 ppm) over three soaking times (12, 18 and 24 h). The priming of 25 ppm ZnO nanoparticles (NP) over a 24-hour period resulted in the highest germination and best growth of the rice seedlings, as evidenced by increased shoot and seedling length and improved overall seedling vigor. The optimized priming treatment (25 ppm ZnO NPs for 24 h), combined with a foliar spray of 100 ppm Zn
