Farmers across the Corn Belt are eager to start planting corn or are in the early stages of planting their 2013 crop. If cool, wet weather continues, planting will be delayed for many growers and prompt questions about switching to earlier-season corn hybrids....More

The latest Crop Progress Report from USDA puts overall corn planted at just 5%. This is only 1 point ahead of last week, and is 26 points behind the five-year average. (Is it necessary to mention that last year nearly half of the overall corn crop was in the ground? Probably not.)...More

Modern hybrids absorb more than half of their final N content after flowering. In fact, they absorb 27% more total N from the soil after flowering than hybrids grown between 1950 and 1990, says a newly released Purdue study. Today’s hybrids absorb more grain-N during grain fill, as opposed to N being remobilized from plant leaves and stems. The higher amount and duration of N uptake contributed to better grain yields, even as actual grain N concentrations decline; hybrids are much more efficient. But as corn plants increase N use, they increase their uptake of other nutrients....More

Carter Charles manages insects and weeds in his corn fields near Cyrus, Minn., without the benefit of genetically modified seeds....More

A historical analysis of corn research shows that new hybrids are taking up more nitrogen than older plant varieties after the crucial flowering stage – a clue as to how plant scientists will need to adapt plants to increase yields....More

Mistakes made during crop establishment are usually irreversible, and can put a ceiling on a crop's yield potential before the corn plants have even emerged. The following are some proven practices that will help get a corn crop off to a good start....More

Applications of liquid manures have the potential to provide nitrogen (N) that can be counted toward meeting the needs of the corn crop and substituting for 28% or other fertilizer N sources. Research on the application of manure preplant or sidedress to corn has been ongoing in Ohio for several years....More
