Tanzania field trial finds soil testing and subsidies can increase fertilizer use and maize yields
URBANA, Ill. – The right mineral fertilizers applied appropriately can alleviate nutrient deficiencies in soils and increase crop yields, but most small-scale farmers in Sub-Saharan Africa do not have their soils tested to reveal these deficiencies.
Resolute scientific work could eliminate wheat disease within 40 years
URBANA, Ill. – Wheat and barley growers know the devastating effects of Fusarium head blight, or scab. The widespread fungal disease contaminates grain with toxins that cause illness in livestock and humans, and can render worthless an entire harvest. As Fusarium epidemics began to worsen across the eastern U.S. in the 1990s and beyond, fewer and fewer farmers were willing to risk planting wheat.
First dicamba-resistant waterhemp reported in Illinois
URBANA, Ill. – University of Illinois weed scientists have confirmed resistance to the herbicide dicamba in a Champaign County waterhemp population. In the study, dicamba controlled 65% of the waterhemp in the field when applied at the labeled rate. And in the greenhouse, plants showed a 5-to-10-fold reduction in dicamba efficacy compared with sensitive plants.
New summer program offers ACES undergrads hands-on rice research in the Philippines
A new summer program will allow College of Agricultural, Consumer and Environmental Sciences (ACES) undergraduates to spend six weeks in the Philippines conducting hands-on research in rice science at the International Rice Research Institute.
Nitrogen calculators not created equal, according to Illinois study
URBANA, Ill. – When deciding how much nitrogen fertilizer to apply, farmers have options. The standard tool for the Midwest – the maximum return to nitrogen (MRTN) calculator – offers a static recommendation. It is based on hundreds of field trials, but doesn't vary much year to year.
Latin American rice breeding gets a boost from genomic tools
URBANA, Ill. – How do you like your rice? Sticky, fluffy, brown, or white? These qualities, in addition to grain length, width, appearance, and other traits, are hugely important predictors of rice sales and consumption worldwide. And region matters. Rice preferences in Latin America, for example, are very different from those in West Africa, Japan, India, and elsewhere.
Comparing photosynthetic differences between wild and domesticated rice
URBANA, Ill. -- Millions of people in Asia are dependent on rice as a food source. Believed to have been domesticated as early as 6000 BCE, rice is an important source of calories globally. In a new study from the RIPE project, researchers compared domesticated rice to its wild counterparts to understand the differences in their photosynthetic capabilities. The results can help improve future rice productivity.
Sweet corn yield gain over 80 years leaves room for improvement
URBANA, Ill. – New research from the University of Illinois shows sweet corn, when planted at high densities, has steadily increased in yield since the 1930s. The historical view underscores the importance of planting modern density-tolerant hybrids at their optimal densities, and suggests an opportunity to improve density tolerance even more.
Weed goes off script to resist herbicides
URBANA, Ill. – Cementing waterhemp’s reputation as a hard-to-kill weed in corn and soybean production systems, University of Illinois researchers have now documented the weed deviating from standard detoxification strategies to resist an herbicide that has never been commercialized.
Machine learning reveals genes for nitrogen use efficiency in corn
URBANA, Ill. – Machine learning can pinpoint genes of importance that help crops grow with less fertilizer, according to a new study published in Nature Communications.
