In-Season Agronomy


Projects in our In-Season Agronomy category span the decisions you make each year related to rotational crops, variety selection, planting strategies, nutrient management, weather challenges, etc., all with the goal of sustainably maximizing yield and profit.


University of Illinois Crop Science Variety Trials – Protein, Oil and SCN Resistance2024-04-09T14:44:29-05:00

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.

An Economic Evaluation of the Impacts of Site-Specific Management for Increasing Soybean Production in Southern Illinois2023-12-20T16:22:26-06:00

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.

Evaluation and Commercialization of SOYLEIC Varieties in Illinois2023-12-20T16:20:02-06:00

To help Illinois soybean farmers capitalize on market opportunities for high oleic, low linolenic (HOLL) soybean oil, this project continues the breeding efforts to select and license varieties that combine competitive yields with the value-added SOYLEIC™ trait.

Evaluating Leaf Nutrient Tissue Testing and Relation to Soybean Grain Yield2023-12-20T16:26:04-06:00

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.

Enhancing the Profitability of Wheat-Soybean Double Cropping2023-12-20T16:22:58-06:00

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.

Injury Potential to Very Early-Planted Soybean from Various Soil-Residual Herbicides / Active Ingredients2023-12-20T16:23:32-06:00

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.

Are you a farmer or advisor?

If you’re a farmer or advisor, we invite you to take our Soybean Production Concerns Survey linked below to help guide future ISA research efforts. We also encourage you to contact us below with specific production challenge research ideas.

Are you a researcher?

If you’re a researcher interested in working with ISA on a project, we encourage you to contact us with your ideas. The RFP will open in early March. Contact us below to be added to the mailing list for more information.
