HERMISTON, Ore. (AP) -- There's plenty of demand for sweet potatoes and a researcher says two years of trials show it could be a good crop for Columbia Basin growers.
At a recent presentation at the Hermiston Farm Fair, Washington State University Extension entomologist Tim Waters said the crop did surprisingly well in trials near Pasco, Wash.
The 2011 and 2012 trials produced yields comparable to those in Louisiana and California, the top two sweet potato-producing states.
The Capital Press reports that sweet potatoes were for decades produced and sold in the Columbia Basin. A labor shortage triggered by World War II ended the crop's run.
