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...

Oats research at the Northwestern Research Center

In any given year oats are typically the first crop to emerge at the Northwestern Illinois Agricultural Research and Demonstration Center (NWIARDC) in Monmouth. Oats were planted in 2015 on April 1 and as of April 17 have between one and three leaves ( Figures ). For the past 28 years, Dr. Fred Kolb has worked at...

We're off and running!

Soil conditions and weather was cooperating enough at the Northwestern Illinois Agricultural Research and Demonstration Center (NWIARDC) to both begin spring nitrogen applications and sow the first corn on April 1. As is the case most years, the first corn planted on the NWIARDC is planted earlier than both the USDA-RMA earliest planting date of April 5 and most local farm fields. Each...

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...

Year-round planning and careful herbicide selection required for fall cover crops

It seems as if cover crops have gotten a lot of press attention in the past several years, reaching a crescendo each year right before the time that they are established – late-summer to early fall. Unfortunately, decisions that were made at the beginning of the season can affect how well certain cover crops establish months later. Application rates listed on herbicide labels were developed in...
