Abstract: The research was done to aim(i) evaluating the effects of three bacteria Burkholderia vietnamiensis(X1), Burkholderia vietnamiensis(X2), Burkholderia vietnamiensis (X3) with nitrogen and phosphorus fertilizer on rice yields (ii) estimating the efficiency of the promising bacteria in improving the yield of rice crops cultivated on acid sulfate soils in the Mekong delta. Field experiments were carried out in two rice crops: summer-autumn (SA) and autumn-winter (AW) seasons in 2015 at three different sites: Long My, Hong Dan and Hon Dat districts, representative for three different acid sulfate soils. Results showed that the rice yield was highest under treatment of X3 in 2015 SA season at Hong Dan and Long My. However, at Hon Dat district, the most efficiency was in the soil treated with X1 bacterium. In 2015 AW season, the treatment of X3 bacterium in combination with 60 kgN ha-1 gave rice yields higher than the treatment of 90 kgN ha-1. The application of phosphorus fertilizer with X1 and X3 bacteria resulted in the highest yields at Hon Dat and Hon Dan district, respectively.
