However, by going up, the concentration of
silver nitrate from 100 to 300 ppm caused a decrease in
the dry weight of plant and dry weight of inflorescence. In
contrast, a raise in the concentration of nano silver from
20 to 60 ppm has led to an improvement in those parameters
(Table 2). Raising the concentration of silver nitrate
from 100 to 300 ppm caused a decline in the seed yield,
but an increase in concentration of nano silver from 20 to
60 ppm leads to arise in the seed yield.
