Scouting shouldn't end until after harvest

Scouting is a season-long commitment, beginning before planting (measuring soil temperature and assessing condition), continues after planting (assessing plant stands and then scouting for disease, insect and weed pressure) only ending after the crop has been harvested. Late season scouting of corn can include monitoring kernels for maturity (black layer) and moisture content and checki...

Impacts of Saturated or Flooded (or Crusted) Soils on Crop Plants

The Northwestern Illinois Agricultural Research & Demonstration Center (NWIARDC) received 6.24 inches of rain in April, more than 3 inches of which fell over the last 5 days of the month. Relatively speaking the Monmouth area lucked out as further South, both Perry and Snicarte accumulated more than 5 inches, Belleville more than 6 inches, Rend Lake nearly 8 inches and Carbondale more than...

Grant Program for Farmers and Ranchers Interested in Increasing Sustainability

From soil erosion to compaction to weed management struggles, farmers know best what is may be limiting crop production or long-term sustainability in the fields that they farm. However during this period of razor-thin margins farmers may be unwilling or unable to fit the costs of experimenting with new conservation practices into their balance sheets. If you are a farmer that has an in...

Why are these corn ears so different? How might this difference affect yield estimates?

While my inclination is to joke and say that the obvious difference must be that the larger ear was grown in Illinois while the smaller ear was grown in another state (four letters, also starts with an 'I'…..), this isn't it. A estimate of yields in a field full of the more moderate-sized ear (612 kernels/ear) at an ear population of 33,000 would be 260 bu/A. While estimated  of a field...

Frost-damaged corn plants re-emerge: Will they act as weeds to their less-damaged neighbors?

Corn planting date trials. Each year, personnel at the Northwestern Research and Demonstration Center establish a replicated planting date trial. The trial established this year will tell us, given the conditions that will be experienced by the crop from planting until harvest, when was the best time to plant corn in Monmouth in 2015. Over a number of years and locations, these...
