The higher concentration of Silver nanoparticles 0.5 mM showed a slightly effects on seed germination percentage and vigour index in tomato seedlings. Silver nanoparticles at concentration of 0.12 mM were less toxic to the tomato, faba bean and barley seedlings. It also reduced the disease incidence.

The interaction effect of different temperature and storage package types showed significant differences in associated seed borne fungi and chemical composition of the stored seed compared with the seeds in the control treatment stored at ambient temperature determined at zero time of storage.
