Abstract
Rhizosphere microorganisms such as phosphate solubilizing bacteria have been widely reported as bacteria that have the ability as phosphate solvents and promote growth. The purpose of this research was to isolate the indigenous bacteria from waste Maja fruit and evaluate whether these could enhance the viability of deteriorating rice seeds. The method used in the first stage of isolation, and evaluation of germination of rice seeds using a completely randomized design. It was revealed that three isolates are isolate 1-1, isolat1-2, and isolate 1-4 were able to solubilise phosphate and produce indole. The Result showed that the three isolates were able to increase the persentage of germination by up to 39,33%, the uniformity of germination by up to 40,76% and germination rate by up 10,46%/d.
