URBANA, Ill. ­– Crop scientists are the original social distancers, muses Allen Parrish, director of the Crop Sciences Research and Education Center at the University of Illinois.

“Planting season is always a demanding time of the year,” he says. “We obviously have restricted working conditions with the social distancing because of coronavirus, but for the most part that’s the nature of our work­. One person on the ground getting things ready; one person in a sprayer or planter. Those are single-operator activities, so the current conditions don’t critically hinder us.

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.

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.

CHAMPAIGN, Ill. —  Rice is a direct source of calories for more people than any other crop and serves as the main staple for 560 million chronically hungry people in Asia. With over 120,000 varieties of cultivated rice (Oryza sativa) across the globe, there is a wealth of natural diversity to be mined by plant scientists to increase yields.

URBANA, Ill. – University of Illinois scientists, with help from members of the Illinois Corn Growers Association, have developed a new, scalable method for estimating crop productivity in real time. The research, published in Remote Sensing of Environment, combines field measurements, a unique in-field camera network, and high-resolution, high-frequency satellite data, providing highly accurate productivity estimates for crops across Illinois and beyond.  

URBANA, Ill. – Only a fraction of conventional row crop farmers grow cover crops after harvest, but a new global analysis from the University of Illinois shows the practice can boost soil microbial abundance by 27%.

The result adds to cover crops’ reputation for nitrogen loss reduction, weed suppression, erosion control, and more. Although soil microbial abundance is less easily observed, it is a hugely important metric in estimating soil health.

Komorebi is a Japanese word that describes how light filters through leaves—creating shifting, dappled “sunflecks” that illustrate plants’ ever-changing light environment. Crops harness light energy to fix carbon dioxide into food via photosynthesis. In a special issue of Plant Journal, a team from the University of Illinois reports a new mathematical computer model that is used to understand how much yield is lost as soybean crops grapple with minute-by-minute light fluctuations on cloudy and sunny days.
