> When I saw the test crop was wheat, I scrolled to see if there were any other crops, saw that there weren't, and abandoned the article because wheat has among the worst yields per area (in terms of kg of edible product per sq meters). Yes, but corn, soybeans, and wheat represent an overwhelming majority of agriculture (at least in the US). If the goal is to reduce energy use, it makes sense to focus on the things that we're making the most of. In 2013 we produced 354M tonnes of corn and 58M tonnes of wheat, and only 13M tonnes of tomatoes and and 3.6M tonnes of lettuce. The fact of the matter is that wheat—despite being low-yield—accounts for an enormously huge percentage of agriculture.
