In ancient China, the development of agriculture was largely defined by regional environmental conditions, leading to the cultivation of distinct primary crops in the north and south.12

Northern China

In the drier, cooler regions of northern China, particularly within the Yellow River catchment, agricultural communities focused on crops well-adapted to shorter growing seasons and arid climates. The most important crops included:12
* Foxtail millet
* Broomcorn millet

Additionally, hemp was cultivated as a significant fiber and oil crop, and members of the mustard family, such as Chinese cabbage, were also domesticated in the north.12

Southern China

In the subtropical, monsoonal regions of southern China, particularly along the Yangtze River basin, the environment favored wetland agriculture. The primary crop was:12
* Rice

Early agriculturalists in the south exploited the lake and marsh margins to grow rice, eventually developing paddy field systems to intensify production. While rice was the staple, these communities also utilized other food sources, including acorns, water chestnuts, lotus roots, and various fruits.12
