This paper reports the effect of growth-promoting bacteria of endophytic and rhizospheric origin on the seed germination process of upland rice variety Ilongkari. Seed germination is the most crucial event in the plant life cycle which determines how the seedling will establish relates to grow and yield. We aimed to determine the effect of Plant Growth Promoting Bacteria (PGPB) isolated from rice plant and the rhizosphere and evaluate their efficiency in stimulating the seed germination process. The experiment was designed in completely randomized design (CRD) with three replicates and carried under laboratory condition in perti dishes with filter paper. Endophytic bacteria Bacillus subtilis RHS 01, Microbacterium testaceum MK LS01 and rhizospheric bacteria Bacillus cereus ABT J11, Bacillus sp. ABT J45 were selected for the study. While the individual treatments with both endophytic bacteria (T1, T2, T3) and rhizospheric bacteria (T4, T5, T6) enhanced the germination process in rice seeds and significantly increased the seedling vigor over that of the control (TW and T0) , it was the combined effect of both (T7) that had significantly greater effect over all the other treatments.
Key words: Endophytes, Rhizospheric bacteria, Plant growth promotion, Seed germination, Seedling vigor.
