Abstract:
The lab experiment was conducted to standardize the concentration of biosynthesized iron nanoparticles (Fe NPs) for seed priming in wheat, which was synthesized through Actinobacteria and Pseudomonas were carried out at Green nanotechnology lab, UAS, Dharwad, Karnataka during 2021-22 in completely randomized design with three replications. The results revealed that, wheat seeds primed with biosynthesized Fe NPs through Actinobacteria (T₆) and Pseudomonas (T₁) at 250 ppm recorded significantly higher germination (97.00 and 96.67%), root length (15.62 and 14.80 cm), shoot length (12.83 and 12.57 cm) and seedling vigour index (2759.65 and 2645.86) respectively, which was on par with Fe NPs seeds priming at 500 ppm biosynthesized through Actinobacteria (T₇) and Pseudomonas (T₂) when compared to control (87.00%, 11.87 cm, 9.80 cm and 1885.29, respectively) (T₁₁).
