Methods

This study was designed to compare corn hybrid performance using farms in the three-county area. Companies submitted two hybrids for evaluation. Due to the number of submissions (44), this trial was split into two groups. The split was made based on maturity information given by the companies with the shorter-season submission from each representative being placed in this group. Maturity ranges in this group were 106- to 113-day hybrids.

Hybrids were randomly planted side by side at each location. No check/tester hybrid was used. Each of the four farms was used as a replication. The hybrids were planted in six-row, field-length strips. Strip length ranged from 397 feet to 1,142 feet. All hybrids were planted with the cooperator's planter. Fertilizer, herbicides, and insecticides were applied according to the cooperator's crop management plan and were all within recommended cultural practices for obtaining optimum grain yields.

1 Yields followed by the same letter are not significantly different at P = 0.05. (F = 1.97, CV = 6.68%) LSD = 15.92
2 Population means were not significantly different overall at P = 0.05. (F = 1.08, CV = 9.37%)

Summary and Notes

Fifteen miles was the longest distance between any two fields for this trial. Fifteen hybrids ranging in yield from 167 to 182 bu/A were statistically the highest-yielding performers in this trial.
