Asparagus planting depth - old vs. new method?

I have a question regarding the proper depth for planting asparagus. IÂve read conflicting information, some of it old and some of it new.

One source printed in 1981 ("Grow the Best Asparagus" by Michael Higgins, Storey Publishing) says that you should vary the depth from about 18 inches to 5 inches to spread the harvest over a longer period. The theory was that the shallower planted crows would come up first and the deepest planted crows would come up last.

The other source printed in 1994 (Ohio State University Extension Fact Sheet) says you should plant them no deeper than 5 or 6 inches. It goes on to say that "research shows that the deeper the crowns are planted, the more the total yield is reduced".

So whatÂs the real story here? Is the more modern method the way to go? Or does planting at different depths do what it is supposed to do (spread out the harvest)? Does anyone have any first hand evidence on this topic?

Thanks!

Bart
