In 2021, the moisture stress highlighted how seeding rates can affect plant-to-plant competition. “We saw the lower seeding rate did better this year, because it wasn’t competing with other wheat plants for soil moisture,” says Missy Carlson, vice president of research, Minnesota Wheat. “That’s something to think about. If you’re seeding at a higher rate, you could be competing with yourself for available soil moisture.” Carlson recommends growers stay within 1.3 to 1.4 million plants per acre when seeding spring wheat in 2022. “We don’t know what the season will be like, but if you’re seeding at a higher rate, around two million plants per acre, you should be safe knocking that back down to the university recommendations.” Carlson was part of the On-Farm Research Summit.
