The population growth compelled to the increase of food s production, demanding bigger productivity, consequently it caused bigger quantity agro-industrial s residue per area. If they are treated and reutilized inadequately they can cause environmental problems. The utilization of these agricultural residues through simple process as decomposition can solve the big environmental problem generated and aggregate value to the producers. The major point of this study is to evaluate the development from passion fruit saplings on different substrata stemmed from decomposition of swine s excrements and vegetable residues. In order to do that were utilized the following vegetable residues: coffee s peel, rice s peel, cane pulp and eucalyptus s sawdust. The treatments utilized were substrata on the portion of 100, 75, 50 and 25% of organic compound stemmed from decomposition and the remainder was filled with soil. Thus, the treatments of: 1 to 4 utilized the compound stemmed from swine s excrements and rice s peel, 5 to 8 utilized compound stemmed from swine s excrements and coffee s peel, 9 to 12 utilized compound stemmed from swine s excrements and cane pulp and 13 to 16 utilized compound stemmed from swine s excrements and sawdust. Also it was utilized one treatment which the composition is known on the market, being 30% of bovine dung and 70% of soil to compare with others treatments. The delimitation used was on blocks called DBC, factorial essay 4x4+1. The factor A was the substratum s type and the Factor B was a proportion of the substratum plus standard treatment. Saplings were evaluated after 60 days of planting. Were evaluated green and dry bulk from aerial part and radicular system. Also were evaluated length from aerial part and radicular system and number of leaves from passion fruit s saplings. The statistics analyses made were: the test Scott-Knott (p<0,05) to the Factor A, regression to the Factor B and contrast to the additional treatment. The treatments shaped by swine s excrements compound and coffee s peel represented better physical/chemistry characteristics. The swine s excrements and rice s peel on the portions of 75 to 100% of organic compounds had better results in almost all characteristics of substratum passion fruit saplings.
