The data online is sortable by column to aid in variety comparison and selection



The purpose of the Ohio Soybean Performance Trials is to evaluate soybean varieties for yield, and other agronomic characteristics. This evaluation gives soybean producers comparative information for selecting the best varieties for their unique production systems.



The entries for each test site were planted in a randomized complete-block design. Each entry was replicated four times and planted in plots 40 ft. long and 5 ft. wide containing four rows seeded at 140,000 seeds per acre.



Entries in Trials.  Performance of entries in The Ohio Soybean Performance Trials are published if seed will be available to Ohio soybean producers for the following planting season. All 2012 entries were submitted voluntarily by seed companies and the Ohio Seed Improvement Association. Entry fee charges were paid per entry and region.


Test by Type. Varieties are grouped, tested and analyzed by type and maturity. All normal and Liberty Link varieties are tested as a group. Roundup Ready varieties are tested in two groups (early and late) based on maturity. The same production, testing and evaluation techniques, except for weed control, were used for normal tests and Roundup Ready tests. The performance of normal & Liberty Link entries and Roundup Ready entries is not comparable statistically because they were not tested and analyzed together. Varieties should only be compared within a test group not between test groups.

Normal and Liberty Link varieties can be found in tables 3, 6, 9.  Use the table below to find varieties by type, region and maturity.



Relative Maturity.  Relative maturity is a rating designed to account for all of the factors that affect maturity date and includes variety, planting date, weather, latitude and disease. Maturity is defined as the “95% brown pods” stage. A variety with a Relative Maturity rating of 3.5 will reach the 95% brown pod stage 5 days later than a variety with a rating of 3.0.  The varieties in each table were tested as a group, and their performance analyzed and reported for that group.


Plant height was measured as a group at physiological maturity.


Seed size is reported as number of seeds per pound.



Yield. Each soybean variety was harvested when the moisture content was between 8 and 12 percent and

yields reported in bushels per acre at 13 percent moisture.


Lodging score. There was no lodging in 2012.


Protein and Oil %. Analysis was determined by near infrared transmittance technology. The test was performed by the OSU Grain Quality Lab using a Tecator Infratec whole grain analyzer calibrated with the Composition Systems Calibration developed at Iowa State University and is reported at 13 percent moisture. 


LSD. A Least Significant Difference (LSD) for yield was computed for each maturity group. LSD's are reported in bushels per acre at 13 percent moisture. Yields of two varieties within a maturity group are significantly different 90% of the time if their yields differ by more than the LSD value shown for that maturity group.


DATA USE.  Inclusion of entries in the Ohio Soybean Performance Trials does not constitute an endorsement of a particular entry by the Ohio State University, Ohio Agricultural Research and Development Center, or the Ohio State University Extension.
