Washington State Sweetpotato Research Looks Promising

Washington State University reports that scientists testing sweetpotato as a potential crop for Washington have achieved better yields than in southern states. Researchers say the sweetpotatoes grow bigger and faster with longer daylight in the Pacific Northwest. They used biodegradable plastic mulch to warm the soil to encourage production. The crop could provide producers with another crop to add in rotation—one that also produces a nutritious and high-value product. In addition, the edible sweetpotato vines could be used as a dairy feed. One potential threat to the crop is wireworm, and researchers are testing varieties for resistance.
