Abstract: The compositionof the substrate utilized asagrowthmedium is directly related to the seedling quality, being important the conduction of studies seeking an increased understanding of its formulation for seedling production. The objective of this study was to check thepotential of the biosolid, cattle manure and coconut fiber in the evaluation of different substrate formulations for the production of seedlings of the forest species Moquiniastrum polymorphum. The experiment was conducted in structures of a forest nursery,localized in the municipality of Lavras-MG,in 110 cm³ tubesarranged in a completely randomized design constituted by five treatments with four replications of 54 seedlingsper plot. When the seedlings reached 150 days after sowing, plant height, collet diameter, height/diameter ratio,shootdry mass,root system dry mass, total dry mass and the shoot/root dry masswere measured, in addition to the Dickson Quality Index -DQI. It was found by means of the results obtainedthat for the production of seedlings of M. polymorphum, the use of substrates formulated from 20 to 60% of biosolid + 20to 60% of cattle manure + 20% of coconut fiber is recommended
