This work studies the effects of two drying processes on quality soybean seed. This study compares simultaneously the effects of two drying processes: the dry-aeration process and conventional drying process. Two drying temperatures (60 and 80°C) and two tempering times (30 and 120 min) were investigated. The seed quality variables analyzed were: tegument break and germinating power. Results show that both drying processes were negative effect on quality seed but dry-aeration process cause less damage. The dry-aeration process with lower temperature and higher tempering time caused less damage than conventional drying process about germinating power and tegument integrity of the soybean seed. In dry-aeration process, the highest tempering time (120 min.) shows a positive effect on soybean seed quality. For temperature analysis, the most relevant damage occurred at the highest temperature.
