The Shafter Cotton Research Station, established here in 1922 by the U.S. Department of Agriculture, developed the Acala varieties, which were exceptionally well suited to the San Joaquin Valley. The quality of the Acala cottons and the marketing advantage of the one-variety cotton district, created in 1925, resulted in premium cottons with a worldwide demand. Through the continued vision and cooperative efforts of growers and researchers, production of Acala cotton became one of California's largest agricultural enterprises.
