Something to think about, Potatoes produce around 9 million calories per acre.
Corn produces around 7.5 million calories per acre. If we want to store corn in bulk, we can stockpile canned corn or store dried corn in mylar bags. A 14.75 ounce can of cream style sweet corn has 60 calories, a 15.25 ounce can of whole kernel corn has 60 calories – at least that is what the labels say on the cans of corn.
Rice comes in third with an estimated 7.4 million calories per acre. Rice is also a popular item to store in mylar bags. If we wanted to break it down to the details, a cup of rice contains about 216 calories.
Soybean 4th with around 2.8 million calories per acre. However, soybean leads the pack of all four in protein production per acre.

With a daily intake of 2,000 calories a person will consume 730,000 calories per year.
2,000 calories per day X 365 days in a year = 730,000 calories.
3,000 calories per day = 1,095,000 calories per year.
Lets just say 1,000,000 calories per person over the course of a year.
For a family of 4, a 1 acre plot of land planted with corn could possibly provide all of the calories needed by that family over the course of a year. But who wants eat corn everyday for a year?
There is a lot of discussion in the survivalist community about getting enough calories after SHTF. If all we wanted to focus on was calories then lets grow nothing but potatoes and corn. Hell yea, lets just stockpile canned corn and canned potatoes by the truckload. But there is this little thing called “nutrition” and “food fatigue.”
If we focus on growing the right crops after SHTF / TEOTWAWKI, calories should not be a problem.
