Rice, the nation's major crop, was grown by about threequarters of all farm households in the early 1980s. Two main types were cultivated: dry, or upland, rice, grown predominantly in the North and Northeast; and wet rice, grown in irrigated fields throughout the central plain and in the South. About half the 1986 production of 19 million tons was grown in the central plain and major valleys in the North; another two-fifths was produced in the Northeast; and about 6 percent came from the South, which was a rice deficient area. Roughly 8.5 million hectares were devoted to rice production in the early 1980s, about 40 percent more than in the early 1960s. The rice yield was highest in the Center, averaging about 1.9 tons per hectare, which was about a third of the yield per hectare in Taiwan and South Korea.
Low productivity was attributed in part to longstanding government policies aimed at keeping consumer rice prices low. The so-called rice premium (in fact an export tax) and occasional quantitative export controls were claimed by opponents to have discouraged production expansion by reducing profitability. Although perhaps a valid argument for commercial rice farming, the policies probably had a minimal effect on the large number of subsistence farmers in the Northeast and North, who produced small, if any, surpluses and whose dry rice was not usually exported. Perhaps more significant was the apparent loss of paddy fertility in the North and Northeast because of poor soil management and the extension in those regions of the growth of lower yield upland rice.
