Crops

URBANA, Ill. – Corn is planted on approximately 90 million acres across the United States every year. With all that data, it takes months after harvest for government agencies to analyze total yield and grain quality. Scientists are working to shorten that timeline, making predictions for end-of-season yield by mid-season. However, fewer researchers have tackled predictions of grain quality, especially on large scales. A new University of Illinois study starts to fill that gap.

URBANA, Ill. – Every summer, a “dead zone” forms in the Gulf of Mexico. Plumes of oxygen-robbing algae, fed by excess nitrogen coming in from the Mississippi River, kill off marine life and threaten the livelihoods of those who fish the Gulf. States bordering the Mississippi River are putting strategies in place to limit nitrogen from wastewater treatment plants, surface runoff, and agricultural fields.

URBANA, Ill. – A team of Extension researchers from the University of Illinois College of Agricultural, Consumer and Environmental sciences has published its 2018 field research results related to crop pests and diseases in Illinois.

URBANA, Ill. – Plants convert sunlight into energy through photosynthesis; however, most crops on the planet are plagued by a photosynthetic glitch, and to deal with it, evolved an energy-expensive process called photorespiration that drastically suppresses their yield potential. Today, researchers from the University of Illinois and U.S.

URBANA, Ill. - The USDA reports released on Nov. 8 contained a lower corn yield, significant revisions to Chinese corn data, and a downward revision of some major corn consumption categories. Corn prices failed to respond despite the smaller crop size projection, explains University of Illinois agricultural economist Todd Hubbs.

Wyffels Hybrids recently donated used, fully operational research equipment to the University of Illinois. The Department of Crop Sciences received a combine with a three-row corn head, as well as a four-row planter. Spare equipment parts were also donated.

When deciding which sweet corn hybrids to plant, vegetable processors need to consider whether they want their contract growers using a workhorse or a racehorse. Is it better to choose a hybrid with exceptional yields under ideal growing conditions (i.e., the racehorse) or one that performs consistently well across ideal and less-than-ideal conditions (i.e., the workhorse)? New research from the University of Illinois suggests the workhorse is the winner in processing sweet corn.

URBANA—The next time the lettuce leaves in your backyard garden turn yellow or tiny, multi-legged creatures frolic on your tomato vines help may only be a mouse click away thanks to a new feature on University of Illinois Extension’s Urban Programs Resource Network. “Common Problems for Vegetable Crops” is the addition.

URBANA -- According to a University of Illinois researcher, setting a threshold for weed tolerance in vegetable crops is the key to helping farmers decide when or even if they should apply herbicides.

"The threshold for controlling insects is determined from performing sweep nets or other means to collect and count insects," said John Masiunas, "but there isn't the same widely-accepted threshold for weeds."
