Abstract: | The present greenhouse study was undertaken to evaluate the effects of co-inoculating methylotrophic Methylobacterium oryzae CBMB20 along with nitrogen-fixing Azospirillum brasilense CW903 or a phosphate solubilizing bacterium Burkholderia pyrrocinia CBPB-HOD on the growth and nutrient uptake of tomato, red pepper and rice. Seed inoculation and soil/foliar application of the bacterial strains alone or under dual inoculation increased the plant growth in terms of shoot or root length and increased the nutrient uptake in the plants studied compared to uninoculated control plants. Co-inoculation of M. oryzae CBMB20 with A. brasilense CW903 or B. pyrrocinia CBPB-HOD improved the N and P concentration of plants, while the results varied among the plant species tested. Also, co-inoculation of the bacterial strains increased the activity of nitrogenase, urease and phosphatase enzymes in soil when compared to uninoculated control or individual inoculations. Though the inoculation effects were analyzed at an early stage of plant growth, the results conclusively suggest that M. oryzae being compatible with other microorganisms in the rhizosphere can potentially be used as individual inoculant or co-inoculated with other plant growth promoting bacteria to increase the production in sustainable agricultural systems. |
