Aceh Patchouli (Pogostemon cablin Benth), an essential oil crop, has been famous for a long time. The best quality patchouli producing area in Indonesia is Aceh Province. Trichoderma harzianum is one of the PGPFs that has been successfully used on a commercial scale while Bacillus thuringiensis as a plant growth-promoting rhizobacteria (PGPR). Improving plant growth, one of its roles, especially seed germination, and shoot elongation. The use of these two microbes indicates that plants grow well and healthy, this is part of the efficiency of plant disease management. In connection with the large number of patchouli plants in Blang Tingkeum Village, Mukim Lamteuba, Seulimum District, Aceh Besar, it is necessary to know whether Application of T. harzianum and B. thuringiensis in the field can increase the growth of aceh patchouli plants (Pogostemon cablin Benth), Plant height, number of shoots, and crown width were observed. The study used a non-factorial Randomized Group Design with 3 treatments and 7 blocks. PGPR and PGPF from both microbes are concluded to play a role in increasing plant growth and production based on the parameters mentioned above. © Published under licence by IOP Publishing Ltd.
