| Abstract:
|
The use of PGPR is an alternative way to reduce the use of chemical fertilizers and their impact on the environment which can improve soil quality and plant productivity. This research aims to study the effect and potential of PGPR on increasing the growth of local aromatic rice plants. 17 rhizobacteria isolates obtained from the local aromatic rice rhizosphere which then were morphologically characterized (size, shape, colony edge and elevation) and biochemically characterized using the Gram and Catalase test. While 17 isolates could produce indole-3-acetic acid, 3 isolates (KBU22, KLE19, and RKGU10) were positive for producing Hydrogen Cyanide. Inoculant PGPR isolates showed significant results in promoting the germination compared to control. KLE25 isolate was superior in all parameters of plant growth in vitro although it was not significantly different from others. PGPR isolates from aromatic local rice rhizosphere can be exploited into biostimulant, biofertilizers and biocontrol agents in enhancing plant growth and attractive strategies to subtitute synthetic fertilizers which is environmental friendly and low-cost.
