Yield and Size of Direct-Seeded Onions in Southern Minnesota with Three Row Arrangements

March 02, 2026
🧅 We’re excited to share the results of last year’s Direct-Seeded Onion Project.
➡️4 long-day storage onion varieties all performed similarly
➡️3 row arrangements performed similarly (size uniformity was not impacted)
➡️Weighted category means is easy, but direct measures of size or variability are probably best
 
With adequate irrigation and weed control, and favorable weather, it’s possible to direct-seed onions and get yield comparable to transplanted in clay-loam soil.
