Impacts of Woody Residue Amendments and Compost on ‘Beauregard’ OrangeFleshed Sweet Potato ( Ipomoea batatas L.)

Orange-fleshed sweet potatoes (OFSP) are valued for their bioactive compounds andability to thrive in nutrient-poor soils. This study investigated the short-term effects ofwoody residues and compost on OFSP, focusing on plant growth, storage rootproduction, and bioactive compounds. Conducted in a co...
