An experiment was carried out in a greenhouse, from march to april/2018, in Crato-CE to evaluate the effects of biofertilizers (common and chemically rich) in substrate irrigated with different saline compositions on phytomass production of yellow pepper seedlings, success variety (952). The experiment was developed using a material or substrate from the first 20 cm of a Red-yellow Latosol. The experimental design was completely randomized in a 5x3 factorial scheme, 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 organic input; with common biofertilizer, and in soil with rich biofertilizer, totalizing 45 treatments, packed in black polyethylene bags with a maximum capacity of 3.0 kg. The biofertilizer, after dilution in a 3:1 ratio, was applied only once to 10% of the substrate volume two days before sowing. Irrigation with saline water affected the morphology and quality of yellow pepper seedlings (cv. Success) but with less intensity in the treatments that received the common and rich organic inputs, respectively.
