| Abstract: | The inhabitants of eastern Sonora were reported by the Spaniards to be more populous and culturally more advanced than other groups in northern México and the southern portion of the American Southwest at the time of Spanish contact. They were also reported to have possessed a well developed agricultural complex. In spite of their achievements, the ancient people of this region have been the subject of few studies because of perceived data limitations. Although they are sparse, data are sufficient to reconstruct the agricultural base. Historical documentations, archaeological remains, and ethnographic analogs indicate that these people relied on a variety of cultivars and agricultural techniques. In addition to dry farming maize, beans, and squash, they also double cropped and irrigated through intricate canal systems. With such elaborate practices and techniques, enough was produced to feed a population of nearly 100,000 and to support a culture that was the only one in the region to be at its zenith when the Spaniards arrived. |
