Foxtail millet in the context of "Millet"

China has been the source of many innovations, scientific discoveries and inventions. Below is an alphabetical list of inventions and discoveries made by Neolithic cultures of China and those of its prehistorical early Bronze Age before the palatial civilization of the Shang dynasty (c. 1650 – c. 1050 BC). These include the Bronze Age Erlitou culture and the semi-legendary Xia dynasty that, unlike the Shang, is not yet confirmed to have existed with evidence of contemporary texts.

The contemporaneous Peiligang and Pengtoushan cultures represent the oldest Neolithic cultures of China and were formed around 7000 BC. Some of the first inventions of Neolithic China include semilunar and rectangular stone knives, stone hoes and spades, the cultivation of millet and the soybean, the refinement of sericulture, rice cultivation, the creation of pottery with cord-mat-basket designs, the creation of pottery vessels and pottery steamers and the development of ceremonial vessels and scapulimancy for purposes of divination. The British sinologist Francesca Bray argues that the domestication of the ox and buffalo during the Longshan culture (c. 3000 – c. 2000 BC) period, the absence of Longshan-era irrigation or high-yield crops, full evidence of Longshan cultivation of dry-land cereal crops which gave high yields "only when the soil was carefully cultivated," suggest that the plow was known at least by the Longshan culture period and explains the high agricultural production yields which allowed the rise of Chinese civilization during the Shang dynasty. Later inventions such as the multiple-tube seed drill and the heavy moldboard iron plow enabled China to sustain a much larger population through greater improvements in agricultural output.

Panicum miliaceum is a grain crop with many common names, including proso millet, broomcorn millet, common millet, hog millet, Kashfi millet, red millet, and white millet. Archaeobotanical evidence suggests millet was first domesticated about 10,000 BP in Northern China. Major cultivated areas include Northern China, Himachal Pradesh of India, Nepal, Russia, Ukraine, Belarus, the Middle East, Turkey, Romania, and the Great Plains states of the United States. About 500,000 acres (200,000 hectares) are grown each year. The crop is notable both for its extremely short lifecycle, with some varieties producing grain only 60 days after planting, and its low water requirements, producing grain more efficiently per unit of moisture than any other grain species tested. The name "proso millet" comes from the pan-Slavic general and generic name for millet (Serbo-Croatian: proso/просо, Czech: proso, Polish: proso, Russian: просо).

Proso millet is a relative of foxtail millet, pearl millet, maize, and sorghum within the grass subfamily Panicoideae. While all of these crops use C4 photosynthesis, the others all employ the NADP-ME as their primary carbon shuttle pathway, while the primary C4 carbon shuttle in proso millet is the NAD-ME pathway.
