Abstract

The production of yellow passion fruit seedlings is common among producers. Low cost techniques to maximize and reduce the cost of production with the application of cattle manure make the production of seedlings feasible. The objective of experiment was to evaluate different concentrations of cattle manure in substrate with and without liquid the biofertilizer in the production of yellow passion fruit seedlings. The experiment was carried out at the Universidade Estadual da Paraíba, Catolé do Rocha county, Paraíba state. The experimental design was completely randomized, in a 5 × 2 factorial scheme, with 5 repetitions end 3 plants per plot. The treatments consisted of five concentrations of cattle manure (0, 20, 40, 60, and 80% of the substrate volume), without and with the biofertilizer (10 mL plant^-1). Sixty days after sowing, the following items were evaluated: plant height; number of leaves; root length; leaf area; leaf fresh mass; stem fresh mass; root fresh mass; aerial part fresh mass; total plant fresh mass; aerial part dry mass, and the Dickson quality index. The concentrations between 38 and 69% of composted cattle manure combined with the application of liquid biofertilizer increased the initial growth of yellow passion fruit plants, making its use feasible in the production of seedlings.
