Biofertilizers are organic products usually obtained from an anaerobic process, evaluated mainly as phytoprotectors for agriculture, although they can improve fruit production. By this way, a field experiment was carried out in Remigio County, Paraiba State, Brazil, to evaluate the effects of two bovine biofertilizers on yield, medium mass and quality of papaya fruits (Carica papaya L.), 'Baixinho de Santa Amalia cultivar. Treatments were distributed in a randomized complete blocks design with three replications and 15 plants in each parcel, in a 2 x 5 factorial arrangement, with two biofertilizers: simple (water and fresh bovine manure) and supermagro (water, fresh bovine manure, macro and micronutrients and a protein mix), applied in soil under liquid form at five volumes, as follows: 0.0; 0.5; 1.0; 1.5; e 2.0 L cave(-1). There was no statistical difference between biofertilizers for fruit mass, yield and external and internal fruit quality variables, while between volumes differences were registered for both biofertilizers. The results, except for fruit firmness, registered positive effects of the biofertilizers on 'Baixinho de Santa Amalia' papaya cultivar in relation to yield and physical and chemical fruit quality
