The experiment was carried out in the greenhouse of Sebelas Maret University Surakarta. Using a completely randomized design with 2 factors. Factor I was the inoculation of Phosphate Solubilizing Bacteria consisting of 3 levels, namely without inoculation of phosphate solubilizing bacteria (I0), Bacillus subtilis inoculation (I1), and Pseudomonas fluorescent inoculation (I2). The second factor are the type of organic material consisting of 4 levels, namely: no organic matter (B0), rice straw (B1), Tithonia diversifolia (B2), and Leucaena leucochepala (B3). The results showed that the use of Tithonia diversifolia organic matter independently proved to be the most effective in increasing available P in the soil by 261%.
