Soybean cultivation because of its importance in global agribusiness, has been the target of much agronomic research. This study compared the performance of seed produced from lots of different seed sizes, during the 2006/2007 growing season. Three cultivars were used and the seed size was standardized with sieves of 5.5 and 6.5mm The experiment was carried out in the experimental area of the Federal Technological University of Parana, Pato Branco campus. After harvest, the following were evaluated : cultivar productivity, weight of a thousand seeds, number of pods per plant and number of seeds per pod. The results showed that the size of seeds used in planting did not affect the productivity of the soybean varieties studied.
