Cover Crop Series: Emerald Okra

  Estimated read time:

Emerald Okra, believe it or not, is an excellent summer cover crop. It is tolerant of drought, thrives in hot weather and is adapted to a range of soil types. Okra makes a large plant and an impressive taproot that can break up compacted soil layers. Seeding rate was 15 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.
