The future of agriculture depends on the recruitment of skilled and forward-thinking professionals prepared to confront evolving issues such as seed engineering, climate adaptability, and disease tolerance. The program benefits from SIU’s ideal proximity to vast Midwestern farmlands and crossroads-climate patterns. Because of the importance of the soybean to US agriculture, we emphasize soybean production, from soil science to plant genetics and crop yield management, we leave no research field untilled in pursuit of maximum performance, sustainability and quality.
