As a result of the persistence of some UI corn researchers, today's sweet corn not only lives up to its name in taste, it maintains its high quality for more than a week, long enough to get it into stores and onto dinner tables. Jerald "Snook" Pataky, UI plant pathologist in the College of Agricultural, Consumer and Environmental Sciences, has researched the history of UI’s contribution to the existence of today's supersweet corn and will be one of the featured speakers at Agronomy Day on Aug. 21. sCorn better used as food than biofuel, study findsJun 20, 2017 9:00 am5083 views Corn is grown not only for food, it is also an important renewable energy source. Renewable biofuels can come with hidden economic and environmental issues, and the question of whether corn is better utilized as food or as a biofuel has persisted since ethanol came into use. For the first time, researchers at the University of Illinois have quantified and compared these issues in terms of economics of the entire production system to determine if the benefits of biofuel corn outweigh the costs.Cahokia's rise parallels onset of corn agricultureMay 14, 2020 8:15 am4932 views Corn cultivation spread from Mesoamerica to what is now the American Southwest by about 4000 B.C., but how and when the crop made it to other parts of North America is still a subject of debate. In a new study, scientists report that corn was not grown in the ancient metropolis of Cahokia until sometime between A.D. 900 and 1000, a relatively late date that corresponds to the start of the city’s rapid expansion.Scientists tweak photosynthesis to boost crop yieldNov 17, 2016 1:00 pm4756 views Researchers report that they can increase plant productivity by boosting levels of three proteins involved in photosynthesis. This confirms a hypothesis some in the scientific community once doubted was possible.Many Midwestern retailers sell mislabeled invasive vinesJan 8, 2018 9:00 am4688 views Gardeners hoping to celebrate the beauty of American bittersweet – a native vine that produces orange berries in the fall and is used for wreaths – may be unwittingly buying an invasive bittersweet instead. That’s because many Midwestern retailers are selling oriental bittersweet with labels misidentifying it as the native plant, researchers report. These sales are occurring in stores and online.Agricultural fungicide attracts honey bees, study findsJan 8, 2018 9:30 am4582 views When given the choice, honey bee foragers prefer to collect sugar syrup laced with the fungicide chlorothalonil over sugar syrup alone, researchers report in the journal Scientific Reports.Ag robot speeds data collection, analyses of crops as they growMar 12, 2018 8:45 am4139 views A new lightweight, low-cost agricultural robot, developed by a team of scientists at the University of Illinois, could transform data collection and field scouting for agronomists, seed companies and farmers.
