Sweet potatoes (Ipomoea batatas) have emerged as a globally significant commodity, valued for their nutritional density, climate resilience, and versatility across food, feed, and industrial applications. Unlike regular potatoes, sweet potatoes offer higher beta-carotene content (especially orange-fleshed varieties) and thrive in marginal growing conditions.
