Seed quality is critical factor for seed germination and plant development. This study was carried out by priming of rice seeds with different concentrations (0, 25, 50, 75, 100, 125, 150, 175 and 200 ppm) of biosynthesized silica nanoparticles. Silica nanoparticles ( nm) were biosynthesized by using rice husk as waste material. | Effect of rice husk silica nanoparticles on rice Oryza sativa L. Seed Quality
