Intercropping techniques like the Three Sisters, where maize, beans, and squash are grown in an intermixed arrangement, have sustained communities in the Americas for thousands of years and continue to be practiced around the world. In collaboration with the Catawba Indian Nation, we assessed the yield and labor demands required when farming with Three Sisters versus monoculture arrangements. Our results illustrate how farmers could use different planting strategies depending on their priorities (e.g., maximizing yield) and available resources (e.g., conserving land, seeds, or labor). Studies like these can help inform food sovereignty programs and support cultural initiatives in Native communities.
