The field experiment was conducted with the objective to determine the type of suitable bacteria to be used for cultivating tithonia as hedgerow to increase dry matter and nutrient yield of tithonia in Ultisols. There were 5 treatments ; K = without bio-agents; L=phospahate diluting bacteria (PDB); M= Azospirillium; N= PDB + Azospirillium; and O= PDB + Azospirillium + Azotobacter, using a randomized block design (RBD) and 3 replications. Those bacteria treatments were re-inoculated tothe rhizosphere of tithonia in the nursery. Then, the young tithonia was planted as hedgerow in Ultisols for 8 months, and pruned every 2 months. The results showed that the phosphate diluting bacteria, and/or its combination with Azospirillium were the suitable bio-agents for tithonia cultivation in Ultisols.
