A synthesis of 89 studies across six continents has helped clarify which agricultural practices hold water when it comes to helping soils soak up precipitation — a factor critical to mitigating floods, outlasting drought and stabilizing crop yields.
A 65-year comparative analysis between U.S. yields of irrigated and rainfed crops has sounded a message to farmers, land managers and policymakers: Mind the gap. Researchers analyzed annual yields of nine crops on a county-by-county basis from 1950 to 2015.
Researchers at the University of Nebraska and Iowa State University are pursuing an elusive goal: measuring rates of sap flow in corn in real-time, actual fields, and changing weather conditions. Their data on corn water use could lead to improved drought resistance.
Researchers have now sequenced and mapped the genome of proso millet – a feat essential to raising yields of the drought-resistant crop in the Nebraska Panhandle and semiarid regions where population booms foreshadow food shortages.
After years of research a University of Nebraska-Lincoln team led by David Holding has roughly doubled the content of lysine, an essential amino acid, in both popcorn and sorghum. For sorghum it could mean a more complete source of nutrition for many in the developing world.
The past century of climate change has extended the average U.S. growing season by nearly two weeks but driven annual buildups of yield-stifling heat in the West and Northeast, says new research from the University of Nebraska–Lincoln.
While climate change is often described on a global scale, a new University of Nebraska-Lincoln study indicates changing climate trends in the Great Plains between 1968 and 2013 drove about 25% of the collective fluctuations in corn, soybean, and sorghum yields.
