This study aimed to determine the main effect of the application of oil palm shell ash (OPSA), Rhizobium sp., interactions in peat soils on the formation of root nodules and growth of acacia seedling and determine the best combination of treatments that resulted the best growth of acacia seedling in peat soils. This research was conducted using CRD method 4x2 with 3 replications. The first factor was four level of dose of OPSA, namely without OPSA, OPSA 2.5 tons.ha-1 or equivalent to 25 g per polybag, OPSA 5 tons.ha-1 or equivalent with 50 g per polybag, OPSA 7.5 ton.ha-1 or equivalent to 75 g per polybag. The second factor was two level of application of Rhizobium sp. namely: Without Rhizobium sp, Application of Rhizobium sp. 220 ml per polybag. The results showed that the application of OPSA increased the pH of peat soil, the number of root nodules, the number of effective root nodules, roots volume, and dry mass. Application of Rhizobium sp. increased the number of root nodules, the number of effective root nodules and dry mass. Interaction between application of OPSA and Rhizobium sp. increased the number of root nodules, the number of effective root nodules and roots volume. Combination of 7.5 tons.ha-1 OPSA with Rhizobium sp. resulted the best growth of acacia seedling in peat.
Keywords: Acacia, peat, boiler ash, Rhizobium sp.
