Reading the results
Four habits that keep a trial honest.
- Compare inside one trial. Entries in a trial share fields, planting dates and weather. Between trials, yield gaps mostly reflect the ground, not the seed.
- Mind the margin. Each report gives a least significant difference (LSD). A gap smaller than the LSD can be chance. Every trial here links to its report.
- Look for consistency. A variety that beats the average at every site, and in several trials, is a safer bet than one big win. Search a name to see all of its trials.
- One season is one season. Most of these trials are from 2024. Weather drives a lot of any single year; the reports also carry multi-year averages.
