protein content was highly significantly increased by
inoculation of the soil with 6 g/kg, whereas using the
concentrations of 2 and 4 g/kg decreased this content as
compared to the control plants. It is clear that the content
of total protein in both roots and shoots were higher in
plants grown from seeds treated with the metabolic
solution of T. harzianum prior to sowing than that of
plants grown in soil inoculated with T. harzianum. The
maximum increase in such content was recorded by
using 100 µl of the metabolic solution.
