Farmers in China, Uganda move to high-yielding, cost-saving perennial rice
URBANA, Ill. – After more than 9,000 years in cultivation, annual paddy rice is now available as a long-lived perennial. The advancement means farmers can plant just once and reap up to eight harvests without sacrificing yield, an important step change relative to “ratooning,” or cutting back annual rice to obtain second, weaker harvest.
Should maize farmers in Sub-Saharan Africa store or sell their grain?
URBANA, Ill. – Many maize farmers in Sub-Saharan Africa sell their crop at harvest, often because they need funds to pay expenses. Development agencies often support or sponsor harvest-time loans that encourage farmers to store some of their grain for later sale, on an assumption that its market value will increase in months to come. But that’s not a sure bet, as a new University of Illinois study reveals.
Illinois report says native fish overlooked as invaders in U.S. waters
URBANA, Ill. – Rivers split across mountaintops and other geographic barriers may flow only a few miles from one another, but to the aquatic creatures in those waters, the separation could represent millions of years of evolutionary time. So, when an angler or a curious child moves a fish from one side of the mountain or one side of the country to the other, it’s a very big deal to the fish. Some may discover a competitive advantage in a new stream, potentially disrupting eons-old ecological hierarchies.
3,300 hidden fungi coat soybean plants: New research explains significance
URBANA, Ill. – Septoria brown spot may be the common cold of soybean diseases, but that doesn’t mean it’s entirely benign. The ubiquitous fungal disease can cause 10 to 27% yield loss, according to University of Illinois research. For many farmers, the obvious response is to fight back with fungicide, but a new U of I study shows Septoria can actually increase after fungicide application.
Bats protect young trees from insect damage, with three times fewer bugs
URBANA, Ill. – Bats help keep forests growing. Without bats to hold their populations in check, insects that munch on tree seedlings go wild, doing three to nine times more damage than when bats are on the scene. That’s according to a groundbreaking new study from the University of Illinois.
Kaiyu Guan charts the course from Blue Waters to Delta
Kaiyu Guan is a researcher with lofty goals – he hopes to monitor, model and ultimately optimize every farmland. Guan aims to achieve these goals in the coming decade or so. He’s a researcher with a mission; of helping create tools so farmers can check on and manage their crops – every single field – in real-time to maintain a healthy and productive growth cycle. But simply reaching that goal isn’t enough. Guan also hopes to achieve co-sustainability of environment quality and food security.
Learning from chickens
CHAMPAIGN, Ill. – The first thing I notice when we step through white double doors of the growers’ house is that every one of the 1,200 or so chickens in this enormous room has stopped whatever it was doing to stare at us. A few of the birds step closer, peering at our legs as if they want to peck our shoes. But they don’t. They’re just curious. Chickens, I realize, are gawkers.
Best way to estimate costs for invasive plant removal? Get out and dig
URBANA, Ill. – Plants are designed to travel. They might not stand up and walk, but many plants produce seeds or other bits that can be carried long distances by wind or animals and start growing. While that might be great news for the plant, escapes like these can disrupt natural ecosystems and be costly to remove.
But just how costly?
How genetic diversity could avoid threat of deadly disease in endangered deer
URBANA, Ill. – Chronic wasting disease, the prion disease affecting white-tailed deer and other cervids, is spreading. With documented cases in 29 U.S. states, two Canadian provinces, three Scandinavian countries, and South Korea, free-ranging and captive cervids are under threat. Efforts to conserve endangered deer against this backdrop are understandably fraught.
Rooting for ecosystem services: New U of I project goes underground
URBANA, Ill. – Decades of corn breeding efforts emphasizing yield have contributed to modern hybrids with shallower and less complex root systems than their predecessors. Because the breeding and selection of most modern hybrids has taken place in environments with high nutrient concentrations, optimal weed control, and soil moisture conditions, hybrids perform best under high input systems.
