Abstract

The aim of this research was to obtain and to observe the activity of plant growth promoting rhizobacteria (PGPR) isolated from coastal Poaceae, Phragmites karka, on stimulating paddy’s growth. The bacteria were qualitatively on three different selective media: Pikovskaya, JNFb, and tryptophan containing LB media to observe the ability of bacteria to solubilize phosphate, to fix nitrogen, and to produce indol acetic acid (IAA). The selected potential bacteria from each test were studied further as PGPR candidates on stimulating paddy growth in sterilized soil medium. The results showed that there were 6 isolates able to solubilizing phosphate, 6 isolates capable to fixing nitrogen and 8 isolates able to producing IAA. The synergy test resulted in three selected isolates (PP03, RG08 and PI05) were synergistic each other. The application of three isolates as single culture and their consortium stimulated of paddy growth significantly comparing to control (without bacteria) especially in the plant height and root length parameter. The best performance of paddy growth was achieved from consortium of 3 bacterial isolates treatment.
