To test whether permanent beds can grow onions well with only shallow tillage (1.5 inches) as compared to deep and shallow tillage.

In a Nutshell

• Jeff found no difference in onion yield (weight) between the tillage treatments.
• Seeing no adverse effects from using only shallow tillage gives Jeff confidence to try more minimum tillage for bed preparation in the future.
• Yankee variety outperformed Norstar by an average of 20% more by weight.
