Abstract The purpose of this research was to determine the effect of PGPR application, the effect of Trichoderma sp. application, and the effect of the interaction between the application of PGPR and Trichoderma sp. on the growth of oil palm seedling. The research was conducted at the Plant Protection Laboratory and the Field Laboratory of the Departement of Agricultural Production, Jember State Polytechnic. While the research time is Mey 2022 to October 2022. The study used a Randomized Block Design (RBD), with 1 (one) treatment factor, that are: (1) without PGPR and Trichoderma sp. application; (2) PGPR application (density 10 6 CFU); (3) Trichoderma sp. application (density 10 9 spores/ml); and application of PGPR (density 10 6 CFU) + Trichoderma sp. (density 10 9 spores/ml). Each treatment combination was repeated 6 times. Data analysis with F test 5%. The parameters of growth of oil palm seedlings observed were number of leaves, stem diameter, seedling height, and the root volume. The result of the research that the application of PGPR and Trichoderma sp. does not have a significant effect on growth of oil palm seedling, but tends to be better than the control.
