Cover Crop Series: Mancan Buckwheat

  Estimated read time:

Mancan Buckwheat is a short-season crop that begins flowering soon after emergence. Its flowers attract many pollinators. While buckwheat, the crop, and wild buckwheat, the weed, are in the same family, they are different genera and species and are not the same. Buckwheat can be grown as a grain crop to provide an alternative to wheat flour. Buckwheat seems adapted to a wide range of soil types but maybe a little better adapted to lighter soils than heavy ones. Seeding rate was 32 pounds per acre.

These plots were drill planted in 7.5 inch rows in a no-till seedbed on a Heiden clay soil May 15, 2017, at the Noble Research Institute Headquarters Farm in Ardmore, Oklahoma. Planting depth was about 1.5 inches. Seed was placed on top of soil moisture, and 2.33 inches of rain fell over the next three days. No fertilizers, insecticides or herbicides were applied to this crop. Rainfall was below average after establishment.

About the Cover Crop Series

The Noble Research Institute is testing dozens of cover crop species with potential to help build soil health in the Southern Great Plains. This series features the cover crops we've grown on our Headquarters Farm in southern Oklahoma. These videos explore our results on establishment and growth, ground cover potential, and weed control for each crop.
