Beans/legumes (soybean could be high), sweet potatoes and manioc as well as
sugar beet are up there for the non grass.  Potato may take top spot
though.  I assume this is world wide you are asking about.

Depending on whether banana is considered a grass, it is on the longer list
as is sorghum but I think Sugarcane takes top spot and may be in the top 10.

Calorie-wise, the top 10 are (or were 10 years ago) in order: Wheat, rice,
corn, potato, sweet potato, manioc, sugarcane, sugar beet, bean,
soybean.  Though that doesn't necessarily reflect economic importance, I
suspect there is decent correlation (?)
