Background: Cow urine contains a growth stimulating substance IAA (Indole Acetic Acid) and is a compound from the auxin group. IAA has a good effect on plant growth. Arbucular mycorrhizal fungi have an important role for plants to overcome Al poisoning in marginal soils. Many of the marginal lands in Jambi Province are former coal mining areas. The role of AMF will be better if organic matter is added as a source of nutrition. Therefore, a study was conducted on the effect of a combination of biourine treatment with arbuscular mycorrhizal fungi on the growth and yield of forage in former coal mining areas.Methods: The experiment was conducted in a randomized block design, with six treatments and three replications. The treatments consisted of: (A) biourine 0% + AMF 0 g / clump (control), (B) biourine 0% + AMF 20 g / clump, (C) biourine 30% + AMF 0 g / clump, (D) biourine 30% + AMF 20 g / clump, (E) biourine 45% + AMF 0 g / clump, (F) biourine 45% + AMF 20 g / clump. The variables observed were leaf width, number of leaves, plant length, number of tillers and yield of dry forage. Result: The results showed that the treatment had a significant effect (P less than 0.05) on leaf width, number of leaves, plant length, number of tillers and yield of forage dry matter. The conclusion in this study is that E treatment (biourine 45% + AMF 20 g / clump) is the best.
