    In order to test the application of phosphate solubilizing fertilizer in the field, we selected the representative crop millet in Taitung area to carry out the effect of phosphate solubilizing bacteria on the growth of millet with different phosphorus content. The results showed that the yield of treatment one (phosphate solubilizing bacteria within organic manure) was significantly different between the low and medium soil phosphorus content areas with the control. The application of liquid phosphate solubilizing fertilizer was not significantly different in all areas. The comprehensive fertilization method was based on liquid phosphate solubilizing fertilizer, even if it was applied deep into the root system. There may be a lack of organic matter and nutrients that can sustain the survival of phosphate solubilizing bacteria for a long time, so there is no significant benefit in every treatment. The result showed that the two commercially phosphate solubilizing bacteria in this test have no any millet growth promotion in the high soil phosphorus content area, and in the lowand medium- soil phosphorus content area, the nutrients of soil are not high, so the phosphate solubilizing bacteria with organic manure can be effective.

Key words: Phosphate solubilizing bacteria, Millet, Soil fertility, Taitung area.
