Assessing the Impact of Cover Crops on SCN Populations in Field Conditions

Pest Management Assessing the Impact of Cover Crops on SCN Populations in Field Conditions This project is using five established cover crop fields throughout Illinois to determine how different types of cover crops affect soybean cyst nematode (SCN) populations. Insights will be used to provide the state’s soybean farmers with improved management recommendations. View overview pdf Project Information How do different cover crops impact SCN populations? Could certain cover crops be used to suppress SCN populations? Statewide with emphasis on Southern Illinois There [...]

Enhancing the Profitability of Wheat-Soybean Double Cropping

In-Season Agronomy 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. View overview pdf Project Information When do winter wheat varieties suited to Illinois break winter dormancy? When do they reach maturity, or 14% grain [...]

Evaluating Leaf Nutrient Tissue Testing and Relation to Soybean Grain Yield

In-Season Agronomy 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. View overview pdf Project Information How do soybean plants accumulate and remobilize nutrients from leaves to [...]

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

In-Season Agronomy 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 [...]

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

In-Season Agronomy 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 [...]

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

In-Season Agronomy 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. View overview pdf Project Information How can we streamline data collection from the state’s variety [...]

Understanding the Importance of Cover Crop Planting Date in Illinois Row Crop Production

Conservation Practices Understanding the Importance of Cover Crop Planting Date in Illinois Row Crop Production To encourage farmers to include more cover crops within their cropping systems, this project is comparing 1) different cereal rye seeding dates and rates before soybean, and 2) different planting dates of two clover species after soybean harvest and ahead of corn. Farmers will gain better insights into cover crop planting and seeding rate recommendations and best management practices. View overview pdf Project Information What is the ideal planting [...]
