Little studies have about bean seed drying and is one of more critical stages in the bean seed production. Also the research was conducted to evaluate and to compare the Phaseolus vulgaris L. seedsquality dried by artificial and natural methods. The brown bean cultivar IAPAR 14, for both methods was used in 1993/94, at Instituto Agronômico do Paraná, Ponta Grossa - PR, Brazil. For the cross-flow drier the drying air temperatures used were 60°C in the superior and 50°C in the inferior camera, and the seed temperature was lower than 36°C. The bean seeds dryed in the sun were spread in a cement terrace. The main conclusions were: it was possible to dry the bean seeds with more than 25% to 13% moisture content using both methods; the artificial drying was faster than the natural conditions; the splitted seeds content increased significantly during the artificial drying; natural dried bean seeds could be used as seeds after they were stored for nine months.
