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 28 ft. long and 5 ft. wide containing four rows seeded at 150,000 seeds per acre. Previous crop was corn.


Entries in trials. Performance of entries in The Ohio Soybean Perfor-mance Trials are published if seed will be available to Ohio soybean producers for the following planting season. All 2013 entries were sub-mitted 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 tech-niques were used for normal tests and Roundup Ready tests. The per-formance of normal & Liberty Link entries and Roundup Ready entries is not comparable statistically because they were not tested and ana-lyzed 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. Relative maturity was submitted by seed companies.

Maturity Date. Maturity date is the calendar date when soybean reached the “brown pod” stage. The varieties in each table were tested as a group, and their performance analyzed and reported for that group.

Lodging score. There was no lodging in 2013.

Seed size is reported as seeds per pound.

Protein and oil % Analysis was determined by near infrared transmit-tance technology. The test was performed using a Tecator Infratec whole grain analyzer calibrated with the Composition Systems Calibration de-veloped at Iowa State University and is reported at 13% moisture.

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% moisture. Yield data from the Delaware County location is not included in this report due to variability caused by excessive precipitation.

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


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.
