ABSTRACT
The role of the tea commodity in the economy of Indonesia is quite strategic. Various types
of microorganisms in nature have been known to increase the benefit of the root function,
suppress disease, and accelerate plant growth. This study aimed to determine the potential
of indigenous bacteria (Azoto II-1, Acinetobacter sp., bacteria Endo-5, bacteria Endo-65
and Endo-76) on the growth of tea plants and their potential in increasing resistance to
blister blight disease. The test of microbes’ potential effect on growth and blister blight
was conducted in Gambung, West Java in an experimental field using a randomized block
design (RBD) with six treatments and each treatment was replicated four times. The composition
of the treatments was: A) Endo-5; B) Endo-65; C) Endo-76; D) Azoto II-1; E)
Acinetobacter sp.; and F) control (without microbes). Bacterial suspension was applied directly
to the soil at a dose of 2 l · ha−1. The bacterial suspension was applied six times at
1 week intervals. The results of field observations indicated that the intensity of blister blight
decreased in all treatments but did not significantly differ from the control. Meanwhile, the
results of Acinetobacter sp. treatment in tea shoots was 17.26% higher than the control.
