Abstract: In the process of production of seedlings the formulation of substrates that supply the nutritional needs and make available appropriate humidity tenor is relevant for the success and the reduction of costs of the producing with other inputs. In this perspective, it is known that alternative substrates are rich in organic matter, which possesses extenuating action for the harmful effect of the salinity. Therefore, it was aimed at to evaluate the effect of saline waters and formulations of substrates in the production of seedlings of yellow passion fruit plant. Experiment was driven in atmosphere protected in the dependences of the Federal University of Campina Grande, Pombal, Paraíba. The randomized block design was used in factorial outline 5 × 5, being five levels of salinity of the irrigation water (0.3; 1.3; 2.3; 3.3 and 4.3 dS m-1) and five substrates- S1 = soil; S2 = soil, goat manure and bovine manure (1-1-1); S3 = soil and goat manure (3-1); S4 = soil and bovine manure (3-1); S5 = soil, goat manure and bovine manure (3-0.5-0.5). To the 52 days after the sowing the growth analyses and quality of the seedlings were checked. The growth of the passion fruit plant seedlings was inhibited by the salinity in the irrigation water. However, the use of organic inputs in the formulation of the substratum lessens the harmful effect of the saline stress, being the best substratum, soil and bovid manure in the proportion 3-1.
