Potential of Phosphorus Solubilizing Purple Nonsulfur Bacteria Isolated from Acid Sulfate Soil in Improving Soil Property, Nutrient Uptake, and Yield of Pineapple (Ananas comosus L. Merrill) under Acidic Stress

Figure 1

Effects of added liquid biofertilizers containing P solubilizing purple nonsulfur bacteria and phosphorus fertilizer levels on the total phosphorus uptake of pineapple cultivated in acid sulfate soil. Bars with the same lower letters were insignificantly different; treatments were statistically different at 5%; W48: Rhodobacter sphaeroides W48; W42: R. sphaeroides W42; W48 + W42: a mixture of R. sphaeroides W48 and R. sphaeroides W42.
