Abstract: An experiment was conducted to evaluate the effects silver nanoparticles (AgNPs), on different germination parameters of onion varieties Arka Pragati. AgNPs of 100 nm size in five different concentrations, viz. 0, 25, 50, 75 and 100 ppm were used as a treatment. Result reviled that 25ppm concentration of AgNPs has significantly higher percent of seed germination over all other treatments. Further, the same dose also had a positive response on seedling growth. But all other treatment had a toxic effect on seed germination and seedling growth, while the degree of toxicity was positively correlated with the strength of the suspension. AgNPs with strength of 100ppm had the lowest percentage of seed germination but there was no significant difference between 75ppm and 100ppm. Thus, 25ppm concentration of AgNPs was best as seed treatment of onion for better seed germination and seedling growth than others.
