Which crops did River Yuman peoples grow along the Colorado River?

The River Yuman peoples—including the Mojave, Quechan, Cocopa, and Maricopa—cultivated several varieties of corn (maize) in the fertile bottomlands along the Colorado River. In addition to corn, they grew beans, pumpkins, melons, and various grasses.12

These groups relied on the river's annual spring flooding, which deposited fresh silt and provided the necessary moisture for their small, irregular fields in an otherwise arid desert climate. These agricultural harvests were further supplemented by fishing, hunting small game, and gathering wild fruits and seeds.12
