High-oil corn packs punch for pigs
URBANA, Ill. – A new high-oil corn product offers greater amino acid and energy digestibility in growing pigs, according to new research from the University of Illinois.
Team discovers invasive-native crayfish hybrids in Missouri
CHAMPAIGN, Ill. — In a study of crayfish in the Current River in southeastern Missouri, researchers discovered – almost by chance – that the virile crayfish, Faxonius virilis, was interbreeding with a native crayfish, potentially altering the native’s genetics, life history and ecology. Reported in the journal Aquatic Invasions, the study highlights the difficulty of detecting some of the consequences of biological invasions, the researchers say.

Sweet corn yield gain over 80 years leaves room for improvement
URBANA, Ill. – New research from the University of Illinois shows sweet corn, when planted at high densities, has steadily increased in yield since the 1930s. The historical view underscores the importance of planting modern density-tolerant hybrids at their optimal densities, and suggests an opportunity to improve density tolerance even more.
Weed goes off script to resist herbicides
URBANA, Ill. – Cementing waterhemp’s reputation as a hard-to-kill weed in corn and soybean production systems, University of Illinois researchers have now documented the weed deviating from standard detoxification strategies to resist an herbicide that has never been commercialized.
U of I Part of Midwest Climate Center
URBANA, Ill. -- Last week, the U.S. Geological Survey (USGS) and the U.S. Department of the Interior (DOI) finalized an agreement with the University of Minnesota and seven partner organizations — including the University of Illinois Urbana-Champaign — to form a new Climate Adaptation Science Center (CASC). The center will advance scientific research and education in response to climate change impacts in the Midwest.
Crayfish get more interesting at bigger parties, study suggests
URBANA, Ill. – In many North American lakes, a tiny clawed creature has become a big bully. The invasive rusty crayfish roams lakebeds, snapping up snails, bivalves, and water plants, cutting off food supplies for native crayfish and other animals. And when they’re feeling saucy, some mount daring raids on fish eggs, reducing sport-fish populations.
Machine learning reveals genes for nitrogen use efficiency in corn
URBANA, Ill. – Machine learning can pinpoint genes of importance that help crops grow with less fertilizer, according to a new study published in Nature Communications.
Advanced model and field data add up to better cover crop management
URBANA, Ill. – Cover crops are widely seen as one of the most promising conservation practices, improving soil health while also removing carbon from the atmosphere. But while the number of Midwestern farmers planting cover crops has increased markedly in recent years, 2017 USDA Census data show only about 5% have adopted the conservation practice. The reluctance of the other 95% may be due, in part, to a perception that cover crops require more effort and may also negatively affect summer cash crop yield.
$25M tech grant lets Illinois researchers ‘talk’ to plants
URBANA, Ill. – The National Science Foundation (NSF) announced today an investment of $25 million to launch the Center for Research on Programmable Plant Systems (CROPPS). The center, a partnership among the University of Illinois at Urbana-Champaign, Cornell University, the Boyce Thompson Institute, and the University of Arizona, aims to develop tools to listen and talk to plants and their associated organisms.
Think climate change is bad for corn? Add weeds to the equation
URBANA, Ill. – By the end of the century, scientists expect climate change to reduce corn yield significantly, with some estimating losses up to 28%. But those calculations are missing a key factor that could drag corn yields down even further: weeds.
Wetter springs and hotter, drier summers, already becoming the norm in the Corn Belt, put stress on corn during key reproductive stages, including silking and grain fill. But those same weather conditions can benefit the scrappy weeds that thrive in tough environments.
