Abstract
In this study, seedcoat cracking during heated air drying was investigated in five varieties of Minnesota grown soybeans. Effects of initial moisture contents, drying temperatures and time on cracking levels were evaluated. Digital image analysis (DIA) was employed to measure initial sizes and shapes of soybeans in order to evaluate the influence of physical properties of mature seeds on cracking frequency. Seedcoat cracking rates increased significantly with increase in initial moisture content of the soybeans, drying temperature and time. Rapid water loss at higher initial moisture contents led to greater seedcoat cracking. Variety, growing location, and size of soybeans had significant influence on seedcoat cracking. Statistical analysis indicates that interactions between various factors had significant influence on seedcoat cracking.
