It has been a quarter century since corn and soybeans were engineered to withstand the withering mists of the herbicide glyphosate. Initially heralded as a “silver bullet” for weed control, the modified crops and their herbicide companion were quickly and widely adopted across corn and soybean-growing regions of North America. In the years that followed, though, weeds targeted for eradication quietly fomented a rebellion. 

In a newly released TED Talk, Stephen Long a University of Illinois Urbana-Champaign professor of plant biology and crop sciences, detailed his and his colleagues’ efforts to boost photosynthesis in crop plants. He described three interventions, each of which increased crop yields by 20% or more. 

A promising new form of ammonium phosphate fertilizer has been field-tested by University of Illinois Urbana-Champaign researchers.

Three researchers in the College of Agricultural, Consumer and Environmental Sciences at the University of Illinois Urbana-Champaign have been named to the 2023 Clarivate Analytics Highly Cited Researchers list. The list recognizes research scientists and social scientists who have demonstrated exceptional influence – reflected through their publication of multiple papers frequently cited by their peers during the last decade. 

Ozone (O₃) in the troposphere negatively impacts crop growth and development, causing significant decreases in crop yield worldwide. This airborne pollutant does not come directly from smokestacks or vehicles, but instead is formed when other pollutants, mainly nitrogen oxides and volatile organic compounds, react in the presence of sunlight. In an increasingly polluted atmosphere, understanding what plants are tolerant of O₃ is critical to improving crop productivity and resilience.

Waterhemp, the aggressive weed threatening Corn Belt crop production, is throwing curveballs once again, according to researchers at the University of Illinois Urbana-Champaign.

URBANA, Ill. — The Illinois Regenerative Agriculture Initiative (IRAI) marks the successful completion of its first three years with a new name: I-Regen. The name change reflects an ongoing commitment to the future of regenerative agriculture in the Midwest. I-Regen encourages diversified value chains that balance the health and wealth of Midwest agricultural systems, creating a resilient bioeconomy that combats climate change, enhances soil and water quality, supports communities, and ensures food security.

URBANA, Ill. — Illinois farmers can now sample their fields for soybean cyst nematode (SCN) at no cost, thanks to the Illinois Soybean Association (ISA) and the

CHAMPAIGN, Ill. — A multiyear analysis tested whether management zone maps based on soil conditions, topography or other landscape features can reliably predict which parts of a cornfield will respond best to higher rates of seeding or nitrogen application. The study found that – contrary to common assumptions – crop-plot responses to the same inputs vary significantly from year to year. The most unpredictable factor – the weather – seemed to have the biggest impact on how the crops responded to these inputs.

The new findings are reported in the Agronomy Journal.
