The objective of this work was to evaluate substrates compost by organic residues for production of papaya tree seedlings. This research was led greenhouse in the campus of the Federal University of Acre in the period of September to December of 2006. The experiment was installed in design completely randomized with eight treatments and four repetitions, and each experimental unit was constituted of 3 plants. The substrates evaluated were: T1 = plantimax (treatment controls), T2 = compost organic + coconut peel, T3 = compost organic + bed-of-chicken + peel-of-rice carbonized, T4 = compost organic + I manure bovine + peel-of-rice carbonized, T5 = compost organic + earthworm casting + peel-of-rice carbonized, T6 = compost organic + earthworm casting + pit of triturated açaí, T7 = compost organic + earthworm casting + peel of triturated coconut, T8 = compost organic + I manure bovine + peel of triturated coconut. In all the substrates, the representatives were used in same proportions, being still added, 10% of triturated vegetable coal, 1,0 kg.m-3 limestone and 1,5 kg.m-3 of termphosphate, except in the treatment T1 (commercial substratum). The evaluations were accomplished to the 70 days after the planting, being evaluated height of plants, mass of the fresh matter of the aerial part, mass of the dry matter of the aerial part, of the root e total. It was observed that the substrata 4 and 5 presented better acting in relation to the characteristics of the mass of the fresh and dry matter of the aerial part, dry matter of the root and dry matter total, but it didn't differ of the substrate 1 (treatment control), 2 and 8, when the seedling's height was analyzed.
