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), seeds were stored in different packaging material i.e., Polythene and cloth bags under ambient conditions up to 6 months, to study the storage efficacy. The aim of this study is to draw a systematic and comprehensive picture of quality parameters on stored seed of paddy which inhance the production and productivity of paddy. Present data revealed that the highest germination percentage, seedling vigour index I and seedling vigour index II were recorded at initial month but after 6 month of storage highest germin

Conclusion

The highest germination percentage, seedling vigour index I and seedling vigour index II were recorded at initial month but after 6 month of storage highest germination percentage (86.8%) in (T3) Dry Bulk ZnO@50ppm, seedling vigour index I (5306) in (T5) Dry Bulk ZnO@250ppm and seedling vigour index II (18.75) in (T7) Dry Bulk ZnO@750ppm were recorded in polythene bag then cloth bag as compared to both the controls. Significant highest seedling emergence percentage were recorded at initial month but after 6 month of storage highest seedling emergence percentage (84.06%) in (T2) Thiram@2gm/kg recorded in polythene bag as compared to (control 1). Lowest moisture content was recorded at initial month but after 6 month of storage lowest moisture content (8.3%) in (T8) Dry Bulk ZnO@50ppm recorded in polythene bag as compared to both the controls. Significant lowest abnormal seedling and dead seed were recorded at initial month but after 6 month of storage lowest abnormal seedling (4.83%) in
