Abstract

Present investigation was carried out with three carrot viz., Carrot Florence (G1), Deb Kuroda-1 (G2), Deb Kuroda-3 (G3) and different concentration and durations of Ag-Nanoparticles were 20 ppm for 12 hrs (T2), 20 ppm for 6 hrs (T3), 15 ppm for 12 hrs (T4), 15 ppm for 6 hrs (T5), 10 ppm for 12 hrs (T6), 10 ppm for 6 hrs (T7), non-primed seeds (T0) with the objectives for enhancing the germination and vigour. Seed priming is a pre-sowing treatment which results in a physiological condition that allows seed to germinate more efficient. The laboratory experiment was carried out in seed testing laboratory, Department of Seed science and Technology, Bidhan Chandra Krishi Viswavidyalaya, Mohanpur, Nadia, West Bengal, India. From the experiment, it can be concluded that treatments over genotypes, Ag-Nanoparticles 20 ppm for soaking 6 hrs showed best performer as seeds treated with Ag-Nanoparticles 20 ppm for soaking 6 hrs observed the significant higher potential than other priming concentrations and durations. Genotypes over treatments Deb Kuroda-3 was the best genotypes. Ag-Nanoparticles 20 ppm for soaking 6 hrs showed significantly highest performance for seed quality parameter like germination percentage (95.244), germination energy (53.167), seedling vigour Index-I (854.722), and germination index (6.778). Therefore, as pre-sowing treatment Ag-Nanoparticles 20 ppm with a duration of 6 hrs is recommended for treating carrot seed for better seedling establishment.

Conclusion

Carrot seeds were treated with various concentration and duration of Ag-Nanoparticles recorded higher seed quality than control. So, it can be concluded that treatments over genotypes, Ag-Nanoparticles 20 ppm for soaking 6 hrs was best compared to other treatments. Genotypes over treatments Deb Kuroda-3 was the best genotypes. Treatments over genotypes, Ag-Nanoparticles 20 ppm for soaking 6 hrs observed the significantly best than other priming concentrations and durations. Ag-Nanoparticles 20 ppm for soaking 6 hrs showed significantly highest performance for seed quality parameter like germination percentage (95.244), germination energy (53.167), seedling vigour Index-I (854.722), and germination index (6.778). Therefore, as pre-sowing treatment Ag-Nanoparticles 20 ppm with a duration of 6 hrs is recommended for treating carrot seed for better seedling establishment.
