Abstract: Experiment was conducted to evaluate the effects biosynthesized silver nanoparticles (AgNPs) and copper nanoparticles (CuNPs) on different seed quality parameters of chilli variety Arka Lohit. Nanoparticles with different concentration, viz. 10, 25, 50, 75, 100, 200, 400 ppm along with raw silver solution, plant sample 2%, Silver nitrate 0.1mM and Bavistin-2g/lit. Results revealed that 400ppm of silver has significantly higher percent of seed germination (73.66%), seedling vigour index (1363), seedling dry weight (0.31 g), shoot (6.33 cm) and root length (12.16 cm) over all other treatments but there was no significant difference between silver nitrate, Bavistin, plant sample and raw silver solution. CuNPs results reviled that 50ppm of copper concentration has significantly higher percent of seed germination (75.33%), seedling vigour index (1327), seedling dry weight (0.32 g), shoot (5.96 cm) and root length (11.66 cm) over all other treatment. But at higher concentration treatment had a toxic effect on seed germination and seedling growth Thus, 400ppm concentration of AgNPs and 50ppm concentration of CuNPs was best as seed treatment of chilli for better seed germination and seedling growth than others.
