Abstract: The objective of this study was to evaluate the effects of the biofertilizers (common and enriched) in substrate irrigated with saline waters on the quality of the seedlings evaluated by the phytomass from yellow Passiflora edullis. In this sense, an experiment was carried in a greenhouse at the Center of Agricultural Sciences and Biodiversity CCAB/UFCA, Crato-CE, from October/2017 to March/2018. The substrate used was a material of the first 20 cm to depth of a Red Yellow Latosol. The experimental design was completely randomized in a factorial scheme of type 5 × 3, with three replications, referring to the electrical conductivity values of the irrigation water- 0.5; 1.0; 2.0; 3.0 and 4.0 dS m-1, in the soil without the bovine biofertilizer; in treatments with common biofertilizer and, evaluated in the soil with enriched biofertilizer, conditioned in black polyethylene bags with it a maximum capacity of 5.0 kg, totaling 60 treatments. The fermented bovine biofertilizer after dilution in non-saline and non-chlorinated water (0.5 dS m-1), in the proportion of 1-3, was applied only once to 10% of the substrate volume, two days before sowing. The salinity increase of the irrigation water affected negatively the phytomass production, but with less intensity in the treatments with enriched biofertilizer. The enriched and common biofertilizer provided higher growth and consequently higher phytomass production of passion fruit seedlings in relation to the soil without the respective input, independently of the level of salinity of irrigation water.
