Impact of Mesoporous Nano-Silica (SiO₂) on Seed Germination and Seedling Growth of Wheat, Pea and Mustard Seed.

Wide range of nanomaterial applications is helpful to promote sustainable agriculture to the point of nanolevel. With regard to this, biocompatible silica nanoparticles have been used as a nanopriming agent for enhancing seed germination in rabi crops like wheat, pea and mustard. The current study was carried out in a completely randomized block design with four replications. One part of nanosilica (8 g/L) and three parts of Gibberellic acid (GA₃) loaded nano-silica (100 ppm, 125 ppm and 150 ppm) were used for the experimental purpose. The result showed positive significant effect of nanopriming with nano-silica and GA3 loaded nano-silica on seed germination percentage, shoot and root length, seedling length, fresh weight, dry weight and vigour index-I and II at
