Since 1905, the Department of Agricultural Engineering, now the Department of Agricultural and Biosystems Engineering (ABE), has been a leader in providing engineering solutions to agricultural problems in the United States and the world. The department’s original mission was to mechanize agriculture. That mission has evolved to encompass a global view of the entire food production system–the wise management of natural resources in the production, processing, storage, handling, and use of food fiber and other biological products.
History
In 1905 Agricultural Engineering was recognized as a subdivision of the Department of Agronomy, and in 1907 it was recognized as a unique department. It was renamed the Department of Agricultural and Biosystems Engineering in 1990. The department merged with the Department of Industrial Education and Technology in 2004.

Abstract
Field data on crop susceptibility factors (CS) and stress-day factors (SEW30) were reviewed and evaluated. The effects of CS factors and their corresponding values of normalized crop susceptibility factors (NCS) on the relationship between stress day index (SDI) and relative yield (RY) were evaluated. Different sets of CS and NCS values for corn, obtained from different locations in the world, were also compared. The results of this study indicate that the relationships developed between SDI and RY by using CS factors will be significantly different from the ones developed by using the corresponding NCS factors. Also, the use of CS values from other locations could be acceptable for calculating the SDI values for drainage design if local data on SEW30 factors are available.
