Biofertilizer appears as an alternative to replace the use of synthetic stimulant by family farmers in pig bean seeds. These are used in agricultural cultivars providing greater seedling vigor. In this context, the objective was to evaluate the concentrations of biofertilizers as a biostimulant in the germination of pork beans. The experimental design adopted was the completely randomized, in a 2 x 5 factorial scheme, referring to two types of biofertilizers (the base of bovine manure and the base fruit residue) and five concentrations of biofertilizers (0; 25%; 50%; 75% and 100%) in immersion for 10 minutes. The germination speed index, total germination, length of primary and hypocotyl root, width and length of cotyledons and fresh and dry matter of the root, hypocotyl and cotyledons were evaluated. The use of biofertilizer based on fruit residue stimulated the rate of germination speed, germination, primary root, fresh root material and dry matter of the root and hypocotyl of C. ensiformis seeds, however the concentrations do not affect the variables. The application of biofertilizer based on bovine manure provided a significant increase in the size of the hypocotyl, width and length of cotyledon and fresh and dry matter of cotyledons, as well as the concentrations of 50 and 75% of bovine biofertilizer applied to the seeds of C. ensiformis promoted the accumulation of cotyledon fresh matter.
