However, rice plants treated with T. harzianum at
108 spore ml1 had the lowest DS values on days 14
and 21 after treatment and the lowest DI values on
days 7, 14, and 21 after treatment. They also had the
lowest pathogen incidence on the resulted grain, the
highest grain yield, and total grain carbohydrate and
protein. Table 2 showed that while there were no
significant differences in DS in any treatments 7 days
after the initial application, there were significant
differences with regard to the DI. However, 14 days
after the initial application, significant differences in
DS were observed between the rice plots. Plots
treated with T. harzianum at 108 spore ml1 or
Hinosan showed the lowest DS (2.8), while those
treated with T. harzianum at 108 spore ml1 showed
the lowest DI. 21 days after the initial treatment, the
rice plots treated with T. harzianum at 108 spore ml1
or Hinosan showed the lowest level of DS (2.5),
while those plots treated with T. harzianum at
108 spore ml1 showed the lowest DI (46.9%). There
was no correlation between DI and DS since disease
can occur with high percentage on the plant even
although its severity may be low.
Table 3 shows that treatment with T. harzianum at
108 spore ml1 or Hinosan produced the highest
number of filled grains per panicle, the lowest
number of unfilled grains per panicle, the highest
panicle weight, the highest 1000 grain weight, and
the highest grain yield compared to the untreated
control. On the other hand, there is no significant
difference in the grain yield between the Hinosan and
T. harzianum at 108 spore ml1 treatments. Fig. 4
shows that treatment with T. harzianum at
108 spore ml1 or Hinosan gave the minimum
pathogen incidence (3 and 4%, respectively).
