Did the recent rains delay your plans to till the soil for a 2017 soybean crop? You might be glad they did.

In 1995, a long-term research trial was established at the Northwestern Illinois Ag R&D Center (NWIARDC) to study the effects of crop rotation and tillage on corn, soybean and wheat yields and cropping system profitability. There are many factors that go into making the decision about which row crops to grow in a particular region: soil types, growing region and climate, grain prices and th...

Disease Alert: Diplodia ear mold in 2016

Symptoms and signs of Diplodia ear mold. In the past couple of weeks, symptoms of ear mold have popped up at the Northwestern Illinois Ag R&D Center. While most fields have rows upon rows of healthy-looking husk leaves enveloping plump ears, in some fields individual ears stand out as the husk leaves are a bleached or tan color ( Figure ). Upon peeling back t...

Trends in Continuous Corn and Corn-Soy Rotation Planting Dates

Although Twitter came alive this spring with reports of farmers near Pearl, IL (in Pike County) planting corn on March 8, and I spoke with a farmer in Knox County that planted corn on March 22, most people wait for the 'earliest plant' dates dictated by the USDA Risk Management Agency (RMA). RMA sets these dates based upon historical weather patterns, balancing the risks associated with frost a...

Results of a 17-year study investigating the effects of crop rotation and tillage on yield and returns

The results of a study that was initiated at the Northwestern Illinois Agricultural Research and Demonstration Center nearly 20 years ago (fall 2015) were recently summarized by University of Illinois Agronomist Dr. Emerson Nafziger. This study was designed to compare yields and returns among different cropping sequences (continuous corn, corn-soybean, continuous soybean, corn-soybean-wheat and so...

Tillage and continuous soybean production favor charcoal rot at the NWIARDC

Last week's blog post was about several soybean diseases that have been recently observed in Western Illinois. Another disease that may be affecting soybeans in Western Illinois is called charcoal rot. The fungus ( Macrophomina phaseolina ) that causes charcoal rot can cause disease in many different plants...

What is small plot research?

At the University of Illinois Research Centers we do small-plot research. This isn't research that takes place in the highly controlled environment of a laboratory or a test tube, but outdoors. A farm field is a diverse environment, with many abiotic factors (rocks and other inorganic soil components, soil nutrients, residual pesticides, temperature, humidity, wind, precipitation, etc.) and biotic...

Crop rotation, tillage and yields

In 1996, the NWIARDC established a long-term crop rotation and tillage study ( Figure ). Crop rotations included various combinations of corn, soybean and wheat including: continuous corn, continuous soybean, corn/soybean, soybean-wheat-corn, and wheat-soybean-corn. Large rotation plots are split into different tillage treatments: fall tillage and no-tillage ( Figure...
