Hemp yields have been extremely variable when this crop has been planted in new areas by inexperienced farmers. In Wisconsin and Kentucky, where only experienced farmers have grown the crop in recent years, the yields have not varied a great deal. The crop has been reasonably dependable and has not often been injured by storms or droughts.

The average yields per acre for experienced farmers are approximately 2¹/₄ to 2¹/₂ tons of air-dry retted hemp stalks; 850 pounds total fiber. Under the Wisconsin machine-milling system the yields may average 450 pounds line fiber and 400 pounds tow fiber; under the Kentucky hand-breaking system they may average 775 pounds Kentucky rough and 75 pounds tow.

If hemp is planted for seed production, the average yields per acre are approximately 15 bushels or 660 pounds, on bottom land, and 12 bushels on uplands.
