Crops

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.

Over the past decades, Brazil has become the world’s leading soybean producer, as well as the leading consumer of pesticides. Despite concerns about potential public health consequences, little is known about the effects of pesticide exposure in the general population.

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 Plant Clinic, a service of University of Illinois Extension, part of the College of Agricultural, Consumer and Environmental Sciences (ACES) at the University of Illinois Urbana-Champaign. 

As the world focuses on not only solving the climate crisis but also sustaining the world’s food supply, researchers need tools to evaluate how atmospheric pollutants affect crops. Over the past decade, the agriculture community has turned to solar-induced chlorophyll fluorescence (SIF) measurements to detect stresses on plants.

URBANA, Ill. — As a source of protein and biodiesel for cleaner renewable energy, soybean is an important crop worldwide. But is it performing to its full potential? An ambitious effort led by the University of Illinois Urbana-Champaign and the U.S. Department of Energy Joint Genome Institute (JGI) will sequence 400 soybean genomes to develop a “pangenome” — an attempt to characterize all the useful diversity in the genome to create an even more robust and resilient crop.

The College of Agricultural, Consumer and Environmental Sciences (ACES) welcomed dozens of international guests to the Crop Sciences Research and Education Center on August 28 to learn about the latest research in sustainable agricultural production, human dimensions of agriculture, and information management from its renowned faculty.

URBANA, Ill. — A new analysis from the University of Illinois Urbana-Champaign and the USDA-Agricultural Research Service (ARS) has identified the top factors accounting for yield variability in processing sweet corn (used for canned and frozen products), including one within the control of processors. 

URBANA, Ill. — For those whose primary experience with corn is the butter-drenched cob variety, it might come as a surprise that other forms of sweet corn are in trouble. A new University of Illinois Urbana-Champaign analysis shows sweet corn production for frozen and canned products has been steadily shrinking in the U.S. over the past 27 years, particularly in rainfed portions of the Midwest. 

URBANA, Ill. — As summer 2023 marches on, so do the events of Agronomy Days at the University of Illinois Urbana-Champaign, a season-long series providing practical, research-based information that can improve yield, input management, and sustainability on the farm. 

URBANA, Ill. — Bioenergy crops such as miscanthus and switchgrass provide several environmental benefits, but low returns and profit risks are barriers for investment by farmers. A new study from the University of Illinois Urbana-Champaign shows that carbon mitigation payments could increase net returns and reduce income risk, potentially enticing more farmers to grow these crops.
