Here's an article that talks about a study done on that subject.

Comparing by volume can be tricky.  An acre of wheat can yield 3000 lbs,  
while an acre of tomatoes can yield 40 tons -- obviously a gigantic  
difference by volume.  However, in terms of available energy (calories),  
the wheat has only about 1/3 less calories per acre than the tomatoes.   
Still less, but not nearly as much as the volume difference would lead you  
to believe.
