Abstract— One of the most important pulse crops in India is green gram (Vigna radiata L.). Pre-sowing seed priming is a promising strategy to provide value-added solutions that influence the yield and quality of the seed. For selecting the appropriate doses of Ag-nanoparticle and GA3, three doses were taken for each chemical and eight genotypes of green gram were selected. The doses of Ag-nanoparticle were 10 ppm, 20 ppm and 50 ppm and for GA3 50 ppm, 100 ppm, 150 ppm. Eight genotypes of green gram were soaked with three doses each of GA3 and Ag-nanoparticle solution for 6 hours. The laboratory experiment was conducted in seed testing laboratory, BCKV, West Bengal during 2019. Germination percentage and vigor were observed to determine the changes in seed quality after priming with different doses GA3 and Ag-Nanoparticle. While considering treatments over genotypes for GA3, significantly highest germination percentage (99.16) and vigour index (2017.937) were observed when it was primed with 50 ppm GA3. In case of Ag-nanoparticle significantly highest germination percentage (99.31) and vigour index (2102.632) were recorded for 20 ppm, when the average was made over genotypes. So, Ag-Nanoparticle @ 20 ppm and GA3 @ 50 ppm were proved to be appropriate dose in green gram for quality seed production.
Keywords— Green gram, Ag-Nanoparticle, GA3, Seed priming.
