The soybean culture in out season as a practice that consolidates in terms of an option between harvests, could also serve to the production of soybean seeds. The present work was carried out with the objective of evaluating the effect of sowing in out season, on physiological and sanitary quality of seeds of three soybeans cultivars, in west of Paraná state. For such way were conducted four assays in the year of 2005, arranged in a completely randomized block design, with each assay sown in different dates (01/15, 01/30, 02/15 and 03/15). The studied cultivars were CD 202, CD 215 and CD 216. The seeds were evaluated by germination and vigor tests (first counting and accelerated aging) and of health. The seeds produced in “out season” in the year of 2005, to the environmental conditions of the west of Paraná state were not favorable to the attainment of high physiological quality seeds
