This research was perfomed with the objective of evaluating sources and levels of organic matters on productivity and the seed quality in snap-bean, to cultivate Macarrão-trepador. Two experiments were conducted in the Center of Agrarian Sciences of the Federal University of Paraíba period from April to September of 1998, one in the field and the other in the laboratory. The field experiment was carried out evaluate the productivity, whose treatments consisted of four sources of organic matters (earthoworm, chicken manure, bovine manure and caprine) and, five levels (0, 5, 10, 15 and 20t/ha of earthoworm and chicken manure and 0, 10, 20, 30 and 40t/ha of bovine and caprino manure). The experimental design of randomized blocks, with the treatments distributed in factorial scheme of 4 x 5, in four reaplications. In the laboratory, the experiment was to evaluate the quality of the seeds, the treatments were also distributed in factorial scheme 5 x 4, but the design experimental used was interily randomized, with four reaplications. The maximum productivities of seeds were obtained with the levels of 20t/ha chicken manure (3.86t/ha), 29.19t/ha bovine manure (3.46t/ha) and 20.86t/ha caprine manure (3.26t/ha). The seed germinations in laboratory were just influenced by the levels of caprine manure, by 32.49t/ha responsable for 78.2%. The field emergency increased with the levels of chicken manure and, it presented maximum value at the level of 22t/ha caprine manure (88.88%). The financial analysis economically indicated that bovine manure as the source of viable organic matters for organic fertilization of snap-bean for production of seeds, with its cost of application representing 85% smaller than the chicken manure to produce a ton of seeds, providing a true gain of 1335.8kg/ha of seeds, while the chicken manure and caprine manure provided a true gain as of, respectively, 960 and 1135.8kg/ha of seeds.
