<![CDATA[Phosphorus is one of the essential nutrients whose availability is very small in the soil. Research on the effectiveness test of biofertilizer phosphate solubilizing bacteria (PSB) and phosphate fertilizer (SP-36 and rock phosphate) on the availability of soil p and p content in tomato plant tissue to determine the effectiveness of SP-36, Rock Phosphate and PSB in increasing P availability soil. The study used factorial randomized block design with two factors and three replications. The first factor is a phosphate solvent bacterial isolate consisting of two levels, without isolate Pseudomonas sp. and with Pseudomonas sp. The second factor is phosphate fertilizer with five levels of control; SP-36 fertilizer 0.32 g/plant; SP-36 fertilizer 0.63 g/plant; rock phosphate fertilizer 0.41 g/plant; and rock phosphate fertilizer 0.81 g/plant. The data obtained were analyzed using Analysis of Variety and continued with Duncan Multiple Range Test (DMRT) test with 95% confidence level. The results showed that the administration of PSB isolate gave increased P-available, P tissue, plant height, wet weight and dry weight of plant and tomato plant production. The application of SP-36 and rock phosphate fertilizer gave an increase to P-available and P-tissue variables, whereas for the production of SP-36 fertilizer plants with dose of 65 g/plant gave higher yield compared to rock phosphate fertilizer.]]>
