Food Security

Researchers in the School of Integrative Plant Science are advancing food security through development of improved cropping systems, management of interactions with weeds and pathogens, and enhancing food value through breeding innovation

Crop Systems

Using plant genomic diversity and field-data to maximize productivity, minimize resource inputs, and increase stress tolerance
