Brief Project Summary:

The goal of this project is to provide Maryland producers with an unbiased comparison of soybean variety performance across the geographic and climatic regions of the state. It also evaluates yield difference with early planting across all varieties entered in the trial. Varieties from maturity groups 3, 4 and 5 are evaluated at four locations across the state representative of the geographic conditions. Trials include full-season and double-crop systems.

Key Benefactors:
farmers, agronomists, Extension agents

Information And Results
Project Deliverables

Varieties from maturity group (MG) III, IV, and V will be evaluated at four locations across the state representative of the geographic conditions in Maryland. A full-season test will be conducted at all four locations with a double-crop test at two locations on the Eastern Shore. Varieties from MG III and IV will be evaluated at all locations, while MG V will only be evaluated at the Eastern Shore locations. Each variety will be replicated three times per location. Four row plots will be established, at least 20 feet long using a row spacing of 30 inches, with similar maturity group varieties planted adjacent to one another. Seeding rate of 6-8 seeds per foot will be used when tests are planting and a rate of 3-4 seeds per foot will be used where seed is drilled. The center two rows of each plot are harvested with Almaco R1 research combine (Almaco Co., Nevada, IA). Grain yield, harvest moisture, and test weight will be measured for each plot. These data will be collected with a Seed Spector LRX system (Almaco Co., Nevada, IA) and recorded on Microsoft xTablet T1600. Harvest data, including yield, relative yield, moisture, lodging, and test weight will be reported for all varieties at all locations in a summary report to be available for download at the UMD MD Crops website (www.psla.umd.edu/extension/md-crops).

Final Project Results

Update:
The University of Maryland Soybean Variety trials have been completed for the 2022 growing season. Results of the trials can be found at the MD Crops page on the Department of Plant Science and Landscape Architecture website at https://psla.umd.edu/extension/md-crops. The Trials Center team, who performs the work, wrapped up harvest by late November this year and the report was compiled and published online by the beginning of December. This was the second year planting our trials with our refurbished no-till planter, which was modified and outfitted with a seed delivery system in 2021.

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
