Abstract:
The present experiment was conducted during 2021-22 at Green Nanotechnology Lab, UAS, Dharwad, Karnataka. This study involved standardization of priming of wheat seeds with green synthesized silver nanoparticles (AgNPs) through Ocimum sanctum leaf extract. The lab experiment comprised of ten different treatments with three replications in completely randomized design. Seed priming with green synthesized AgNPs at three different concentrations of (250 ppm, 500 ppm and 750 ppm) along with two soaking durations (4 and 8 hours). The results revealed that, AgNPs 750 ppm 4h reported significantly higher germination (92.67%), root length (11.76 cm), shoot length (18.80 cm) and increased seedling vigour index (2832) followed by AgNPs at 500 ppm for 4h and AgNPs at 250 ppm for 4h compared to control (78.00 %), (10.67 cm), (9.33 cm) and (1560) in bread wheat variety UAS-304.
