Zinc and Iron Nanoparticles Using Cow Manure and Their Application as Nano Nutrients

This work investigates the environmentally sustainable production techniques for Zinc (Zn) and Iron (Fe) nanoparticles with a focus on their use as Nano-fertilizers to improve plant growth. Using nanotechnology, which is defined as the manipulation of matter at the nanoscale (1-100 nanometers), will achieve maximum efficiency in terms of nutrient delivery through agricultural practices. The study produced Zn and Fe nanoparticles using cow manure extract in the green synthesis method. Characterization was confirmed through UV-Vis and photoluminescence spectroscopy to achieve nanoparticles. The Nano-fertilizers were applied to chilly and tomato plants, leading to significant increases in chlorophyll content and other parameters like flowers, fruits, leaves, fruit size, clearly showing the potential to improve plant growth and yield.
