Potatoes have great yield in terms of calorie per unit harvested. Other plants, not so much. Think about how much weight you might throw away with a pumpkin or a watermelon.
I have some family members who devoted about an acre and a half to a mix of crops, squashes mostly as they grow the best where they live, and for a family of 5 still had to supplement their diet pretty significantly.
At the same time, they ate more healthily than they ever had before, and often had too much of certain crops that they gave away or sold at the local farmer's market.
