Abstract

The studies were carried out on paddy variety Pusa Basmati 1509 at ICAR- Indian Agricultural Research Institute, New Delhi during 2020-21 with the objective to study the effect of nanoparticles on seed quality parameters. The goal of this study is to draw a systematic and comprehensive picture of quality attributes on seed of paddy which enhance the production and productivity of paddy. The seeds were dry dressed and infused with each of nano and bulk forms of Zinc oxide, Titanium oxide, Silicon dioxide @ 50, 100, 250, 500 and 750ppm along with the two controls i.e., untreated and treated with recommended PoP (Thiram treated @2g/Kg of seeds) and were evaluated for various seed quality parameters Present investigation revealed that, the highest radicle emergence percentage (95.3%) and numerically highest field emergence percentage (97.3%) was recorded in Dry Nano ZnO@250ppm as compared to both the controls. Highest germination percentage (94.7%) in Dry Bulk ZnO@50ppm and highest average

Conclusion

The highest radicle emergence percentage (95.3%) and numerically highest field emergence percentage (97.3%) was recorded in Dry Nano ZnO@250ppm as compared to both the controls. Highest germination percentage (94.7%) in Dry Bulk ZnO@50ppm and highest average shoot length (33.3 cm) in Dry Bulk ZnO@100ppm were recorded as compared to both the controls. Significant highest average root length (40.5 cm), average normal seedling length (67.5 cm) and highest seedling vigour index I (6129) was reported in Dry bulk ZnO@250ppm as compared to both the controls. Significant highest seedlings dry weight (0.2603g) and seedling vigour index II (23.4) was reported in Dry Bulk Zno@750ppm as compared to both the controls.
