The Yangshao culture developed millet-based agriculture in the Yellow River Valley's middle reaches between approximately 5000-3000 BCE. Farmers initially cultivated broomcorn millet, then shifted to foxtail millet as climate conditions changed. Archaeological evidence indicates they used crop rotation, field management, and early manuring practices. This agricultural system supported permanent settlements with painted pottery and organized village structures. The millet farming innovations enabled population growth and provided a foundation for later Chinese agricultural development through adaptation to mid-Holocene environmental changes.
