The Incas also developed a complex system of land tenure and social organization, which helped to promote the widespread adoption of sweet potatoes as a staple crop.

2. The Aztecs

   The Aztecs were another ancient civilization that played a significant role in sweet potato cultivation. They cultivated sweet potatoes in the central and southern regions of Mexico, using advanced irrigation systems to control water supply and promote plant growth. The Aztecs also developed unique varieties of sweet potatoes, many of which remain popular today.

3. The Polynesians

   The Polynesians were skilled sailors and traders who introduced sweet potatoes to the Pacific Islands over 1,000 years ago. They cultivated sweet potatoes on remote islands, using techniques such as mulching and controlled irrigation to promote plant growth in areas with limited resources. The Polynesians also developed a rich tradition of sweet potato cuisine, with dishes such as poi and laulau becoming staples of their diet.
