Millets — Ancient Drought-resistant Grains — Could Help the Midwest Survive Climate Change

By Eva Tesfaye

The Midwest is known for its rows and rows of corn and soybeans that uniformly cover the landscape.

But in central Missouri, farmer Linus Rothermich disrupts the usual corn and soybean rotation with Japanese millet. He has been growing it since 1993.

“Golly, I have to think how far back that is,” he said. “I was a young man and I was looking for alternative crops to grow to make more money. We just weren't making a lot of money in agriculture then.”

Compared to his corn and soybean crops, he spends a lot less on Japanese millet. Because its growing season is shorter, it fits perfectly into the rotation of the crops he already grows. It’s working so well for him that he wants to keep the grain to himself.

“I have recommended it to other farmers, as long as it’s not my Japanese millet,” he joked, pointing out prices likely would drop if a lot of other farmers start growing it.

A climate-friendly crop 

There are several different kinds of millets. In addition to Rothermich’s Japanese millet, there is pearl millet, foxtail millet, proso millet and more. Sorghum can also be considered a millet.

Millets tend to need less fertilizer and are more resistant to insects and diseases, (although sometimes birds like to eat them.) Farmers can also use most of the same equipment for millets as they do for corn and soybeans. And while, so far, millets don’t produce the same yields as those commodity crops, Rothermich says it’s worth it.

The market for millets is not a large one in the United States, except for its use as songbird seed. However, millets could be used for livestock feed, cover crops and even biofuels. Myers said that they could even become a more popular food option as people look for gluten-free alternatives.
