URBANA, Ill. – Drought and heat put stress on plants and reduce grain yield. For some farmers, irrigation is the answer. Many of us assume the practice boosts crop yields by delivering soil water, but it turns out irrigation’s cooling effect on crops is important in its own right.

In a recent U.S.-based study, a research team led by University of Illinois scientists discovered 16% of the yield increase from irrigation is attributable to cooling alone.

URBANA, Ill. ­– Soybean production in Africa and other developing regions has the potential to alleviate hunger and boost local economies. But the transition from traditional crops such as cowpea or cassava to a major commercial crop such as soybean is fraught with challenges.

The soybean cyst nematode sucks the nutrients out of soybean roots, causing more than $1 billion in soybean yield losses in the U.S. each year. A new study finds that one type of fungi can cut the nematodes’ reproductive success by more than half.

URBANA, Ill. – Pigs have better feed conversion rates with copper in their diets, but until now, scientists didn’t fully understand why. Existing research from the University of Illinois shows copper doesn’t change fat and energy absorption from the diet. Instead, according to new research, the element seems to enhance pigs’ ability to utilize fat after absorption, resulting in increased energy utilization of the entire diet.

URBANA, Ill. -- The growing threat of drought and rising water demand have made accurate forecasts of crop water use critical for farmland water management and sustainability. But limitations in existing models and satellite data pose challenges for precise estimates of evapotranspiration — a combination of evaporation from soil and transpiration from plants. The process is complex and difficult to model, and existing remote-sensing data can’t provide accurate, high-resolution information on a daily basis.

URBANA, Ill. – University of Illinois agricultural economists will host a webinar series discussing the impact of the coronavirus on agriculture in the Midwest. The webinar series will kick off on Friday, March 20, at 11 a.m. CDT.

CHAMPAIGN, Ill. —  Like many industries, big data is driving innovations in agriculture. Scientists seek to analyze thousands of plants to pinpoint genetic tweaks that can boost crop production—historically, a Herculean task. To drive progress toward higher-yielding crops, a team from the University of Illinois is revolutionizing the ability to screen plants for key traits across an entire field.

URBANA, Ill. – Edamame may be a niche crop in the United States, but growers and processors still need the best possible information to make sound management decisions. That’s why USDA Agricultural Research Service (USDA-ARS) and University of Illinois researchers are making new plant density recommendations for machine-harvested edamame, at less than half the rate suggested by seed companies.

URBANA, Ill. – Like most invasive species, when the soybean aphid arrived in the Midwest in 2000, it brought none of its natural enemies along for the ride. So, naturally, finding itself in the soybean capital of the world, the tiny insect went bonkers. Taking advantage of a nifty ability to reproduce without mating, populations exploded and the soybean aphid quickly became the number one insect pest affecting the crop.

URBANA, Ill. – Cattle feeders choose distillers grains in feedlot diets as an inexpensive alternative to corn and soybean meal. But until now, no one had studied the effects of the common feed ingredient on bull development and fertility. With bull fertility to blame for a significant portion of reproductive failures in cow-calf operations, University of Illinois researchers decided it was worth a look.
