Abstract:
The present study was carried out on paddy variety Pusa Basmati 1509 at Indian Agricultural Research Institute, New Delhi during 2020-21 with the objective to study the effect of nanoparticles on seed storage potential. 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). Present data revealed that, the highest total dehydrogenase activity (0.766) was reported in (T6) Dry Bulk ZnO@500ppm as compared to both the controls. lowest total pathogen infection (8.3%) and penicillium sp. infection (1%) was investigated in (T7) Dry Bulk ZnO@750ppm as compared to both the controls and the lowest Rhizopus sp. infection (3%) was recorded in (T6) Dry Bulk ZnO@500ppm and lowest Aspergillus sp. infection (2.3%) was recorded in (T8) Dry Nano ZnO@50ppm as compared to both the controls.
