During the pre-modern era, grains such as barley and millet were the main staples. They were supplemented by wheat, sorghum, and buckwheat. Rice is not an indigenous crop to Korea and millet was likely the preferred grain before rice was cultivated. Rice became the grain of choice during the Three Kingdoms period, particularly in the Silla and Baekje Kingdoms in the southern regions of the peninsula. Rice was such an important commodity in Silla that it was used to pay taxes. The Sino-Korean word for "tax" is a compound character that uses the character for the rice plant. The preference for rice escalated into the Joseon period, when new methods of cultivation and new varieties emerged that would help increase production.
