Injury Potential to Very Early-Planted Soybean from Various Soil-Residual Herbicides / Active Ingredients

While interest in planting soybeans earlier continues to increase, concerns around preemergence (PRE) herbicide injury to emerging seedlings continue to linger. Early planting often means cold, wet soil conditions that can delay seed germination and prolong plant emergence. These conditions can reduce the plant’s ability to metabolize PRE herbicides and result in crop injury. This project will test several herbicides and classes of chemistry to better understand which are more prone to cause crop injury under early planting conditions. Learn More

Enhancing the Profitability of Wheat-Soybean Double Cropping

Double cropping soybeans after winter wheat is an attractive approach to enhancing profitability in Midwest crop rotations and improving soil health. To capitalize on this cropping system, this project will identify high-yielding winter wheat varieties that can be harvested earlier and enable earlier planting of double-crop soybeans to maximize soybean yield potential.

Evaluating Leaf Nutrient Tissue Testing and Relation to Soybean Grain Yield

Because soybeans are able to remobilize, or redistribute, nutrients from lower to newly developing nodes, more information is needed to understand which nutrients and in what quantities are made available to new nodes. This project will use tissue testing to gain these insights and help establish more accurate and timely in-season nutrient recommendations to maximize soybean yield. Learn More

An Economic Evaluation of the Impacts of Site-Specific Management for Increasing Soybean Production in Southern Illinois

To help close the soybean yield gap between average and record yields, this project will break down management practices based on the specific needs of different areas within a field. It will define the yield variability within a field as high, medium and low; identify seeding rates that can help optimize yield; better understand the role biologicals can play in crop nutrient utilization; and evaluate the economics of site-specific management compared to whole-field management practices.

University of Illinois Crop Science Variety Trials – Protein, Oil and SCN Resistance

In addition to using the SCIO CNST NIR technology on the combine to determine the protein and oil content of each tested variety, soil samples will be collected at harvest to assess population levels of soybean cyst nematode (SCN). Data will be shared with Illinois farmers through several methods, including the UI Variety Trial website. Learn More
