Final answer:
Indigenous tribes of the Americas, including the Maya, Aztec, Inca, Iroquois, Mississippian, and Pueblo cultures, cultivated corn before the arrival of Europeans. They employed techniques such as the Three Sisters method, showcasing their advanced agricultural know-how.
Step-by-step explanation:
The peoples who cultivated corn in the west before Europeans arrived in America were the Indigenous tribes of the Americas. Essential to many Native American cultures, corn, also known as maize, was a staple crop and a cornerstone of their agriculture. The practice of growing corn dates back thousands of years. Notable civilizations such as the Maya, Aztec, and Inca in Central and South America, and the Iroquois, Mississippian, and Pueblo cultures in North America developed sophisticated farming techniques to cultivate this important crop.
Corn was often grown in conjunction with other crops like beans and squash, a method known as the Three Sisters, which provided a balanced diet and supported sustainable soil fertility. These agricultural practices reflect the deep knowledge and connection these peoples had with the land.
