Abstract: |
Seven rhizobacterial strains isolated from the rhizosphere soil of purple rice cultivated in Dak Lak Province, Vietnam, were evaluated for their effects on the growth and yield of the VH1 purple rice variety under plastic-house conditions. The experiment was conducted using a completely randomized design (CRD) with three replications and nine treatment formulas. The results showed that all seven strains increased the photosynthetic pigment contents in rice leaves at the flowering stage. These rhizobacteria also strongly stimulated the growth of VH1 purple rice, resulting in increases of 11.53-19.71% in the number of tillers per plant, 13.96-37.43% in flag leaf area, and 6.03-34.61% in root length compared with the two control treatments. Moreover, the inoculated strains enhanced disease tolerance, leading to actual yields ranging from 69.31 to 88.36 quintals per hectare, which were 1.41-2.14 times higher than the controls. Overall, Stenotrophomonas maltophilia RDL1B41, Pseudomonas aeruginosa RDLN43, and Enterobacter mori RDLN105 were identified as the most promising rhizobacterial strains, with potential application in biofertilizer development for sustainable rice cultivation. |
