Abstract Terra preta is a black soil found in the Amazon basin in the 15th century with the main characteristics of black and loose has the nature of resistant to leaching, able to provide and maintain nutrients in a very long time, whereas in Indonesia the availability of such land has not yet existed so it is necessary to make and apply terra preta soil with mineral soil base material mixed with charcoal, bones burned with pyrolysis combustion system and other organic materials. In enriching microorganisms, mycorrhizal fungi are added which function to increase nutrient absorption, increase plant resistance to biotic and abiotic stresses, able to maintain growth and production stability. The study aims to determine the effect of the application of terra preta planting media with pyrolysis combustion systems on the growth and production of corn plants using polybags. The results showed that the application of terra preta in general had a good effect on the growth and production of corn compared to plants that only used mineral soil or control media. Application of T1: 100% terra preta treatment on observations of plant height and stem diameter showed the best treatment. On observation of the number of leaves, of wet weight and dry weight of root, canopy, corn seed, corn cob and corn husk of T5 treatment: mineral soil + 15gr mycorrhizae + 80% terra preta showed the best treatment.
