In this project, silica nanoparticle technology was used to boost drought stress tolerance in cotton. Silica nanoparticles with different sizes and shapes have been synthesised. The silica nanoparticles were then coated on cotton seeds. Various concentration of nanoparticles to be used for seed coatings have been tested. Silica nanoparticles/seed mass percentage of 0.6% were found to have the best effect on seed germination and plant development and potentially reduce the irrigation water for cotton growers. The work of this project is known and invited to do showcase at evoke2024 and two international conferences in American. The researcher of this project was selected to be one of 30 global Sustainability Stars recognised by American Chemical Society.
