Increasing Plant Health using Plant Growth Regulator from Rice Rhizobacteria

Plant health is a very important factor in the agriculture system. The presence of plant hormones such as Auxin, gibberellic acid, and siderophores with variation numbers in the plant gives different effects on plant health. Related to the environment rich with rhizobacteria, they have a unique function because rhizobacteria can produce a chemical compound known as Plant Growth Promoting Rhizobacteria (PGPR). The purpose of the research is to study the production of auxin, gibberellic acid, and siderophore from rice rhizobacteria as the source of potential hormones for plant growth. Ten rhizobacteria isolates have been isolated from the rice rhizosphere. They are potential candidates as biofertilizers and biopesticide agents. The hormone production from each isolate was tested by spectrophotometric methods: Auxin at a wavelength of 535 nm with Salkowski's reagent, gibberellic acid at 254 nm, and siderophores at 560 nm with Hardaway's reagent. The results showed the highest auxin hormone was obtained from isolate 10 (3.374 ppm), the highest gibberellic acid from isolate 4 (3.960 ppm), and the highest siderophores hormone from isolate 2 (2.910 ppm). The conclusion of the research is, plant growth regulator from rice rhizobacteria has the potential increasing plant health.
