Abstract:
Groundnut (Arachis hypogaea L.) is referred as ‘King of Oilseeds’. Time immemorable, silver and copper have received substantial attention to enhance the seed quality through seed nano priming. The laboratory experiment was conducted to investigate the effect of green synthesized silver and copper nanoparticles on seed quality parameters in groundnut JL-24 and Dh-256 varieties during 2022-23 at the Department of Seed Science and Technology, University of Agricultural Sciences, Dharwad. The experiment was laid out in Factorial completely randomized design with three replications and nine treatments viz., For T₁, T₂ and T₃ - seeds were primed with silver nanoparticles of concentration 200, 300, and 400 ppm respectively for 1 h. T₄, T₅, and T₆ – seeds were primed with copper nanoparticles of concentration 100, 200, and 300 ppm respectively for 1 h. T₇ and T_{8 -} Seeds primed with 1mM AgNO₃ and 1mM CuSO₄, T₉ – Hydroprimed. Results revealed that among treatments seeds primed with silver nanoparticles 400 ppm recorded higher germination (%) (95.83%), Seedling Vigour Index-II (415), Seedling Dry Weight and lower Electrical Conductivity and seeds primed with 300 ppm silver nanoparticles recorded higher Seedling Vigour Index I, shoot and root length compared to control. Overall, Dh-256 recorded higher seed quality parameters. For germination percent, seedling length, Seedling Vigour Index I, Seedling Vigour Index II, Seedling dry weight and Electrical conductivity interaction between treatments and genotypes was significant.
