Thailand - Crops
Sugarcane has long been widely grown. Some commercialization was reported by the mid-nineteenth century, but the crop became of major importance only after World War II. In the early 1950s, production averaged 1.6 million tons annually, and in the late 1950s self-sufficiency in sugar was attained. In 1960 Thailand became a net exporter of sugar. Rising world prices led Thailand's market-responsive farmers to expand cropped areas in the 1970s. In 1976 sugarcane production reached a record 26.1 million tons, and sugar output totaled 2.2 million tons, the latter amount being considerably in excess of international and domestic demands. Drought in 1977 greatly reduced output and seriously affected many small growers. Declining world prices after 1975, drought, and lower producer prices in 1978 led many farmers to shift to alternate crops. In 1986 about 24 million tons of sugarcane were produced.
Productivity was low compared with other major sugarcane-growing countries (about fifty-three tons of sugarcane per hectare against Taiwan's seventy tons and Indonesia's eighty tons in the mid-1970s). Introduction of new varieties and improved cultivation and cropping practices were needed to raise output levels. The principal sugarcane-growing areas were in and around Kanchanaburi Province and in Chon Buri Province in the Center. Sugarcane was also grown in the Northeast and in the North around Chiang Mai, Lampang, and Uttaradit.
Kenaf, a coarse fiber similar to jute but of somewhat lesser quality, is native to the country and has long been grown for local use in making sacks, cord, and twine. Commercial cultivation began in the Northeast in the 1950s, and production was largely concentrated in the central and eastern parts of the region in 1980. World shortages created by the Indo-Pakistani War of 1965 temporarily stimulated Thai production of jute, as did shortages resulting from the 1971 civil war in Pakistan. The recovery of jute cultivation in Bangladesh (formerly East Pakistan) and broad swings in producer prices led many Thai farmers in the late 1970s to replace kenaf with cassava, which commanded a higher return. The 1984 kenaf crop was estimated at about 200,000 tons, compared with an average annual output of over 400,000 tons in the previous decade. Increased world demand, however, was expected to encourage a revival in planting.
Tobacco, an important foreign exchange earner, had long been grown by farmers for personal and local use. Virginia flue-cured tobacco had been produced commercially since the 1930s, but export began only in 1956. Some burley and oriental (Turkish) tobacco was also grown. United Nations sanctions against Rhodesia beginning in the mid-1960s opened new markets, and production of Virginia tobacco rose from 13,700 tons in 1967 to more than 50,000 tons in 1981. About half of the commercial tobacco was grown in the North and another quarter in the Northeast. Tobacco growers were licensed, and a large number operated under the aegis of the state-owned Thai Tobacco Monopoly.
Pineapples, exported chiefly as canned fruit and juice in the early 1980s, were grown solely as a supplementary crop for local use until the first pineapple cannery was opened in 1967. A shortage of fruit led several canneries to establish large pineapple plantations (ranging up to more than 3,000 hectares--in sharp contrast to the smallholding character of most Thai agriculture), which supplied about 40 percent of cannery needs in the late 1970s. The industry grew dramatically, and by the early 1980s Thailand was one of the world's largest exporters of pineapples, producing about 1.6 million tons in 1984.
Production and export of coffee expanded rapidly after Thailand became a member of the International Coffee Organization in 1981. Exports of coffee beans, most of which were grown in the South, reached 20,600 tons in 1985.
Maize was believed to have been introduced by Spanish or Portuguese traders in the sixteenth century. Export interest and profitability led to increased maize cultivation after World War II and the introduction of the so-called Guatemala strain in 1951. Output rose rapidly thereafter to almost 600,000 tons in 1961, over 1 million tons in 1965, and 2.3 million tons in 1971. A record 5 million tons were produced in 1985. Fertilizer use was limited, however, and there was concern that yields would gradually decline. The grain was grown throughout Thailand, but the uplands around the central plain were especially suitable. Weather conditions usually permitted commercial growers to produce two crops a year.
Climatic and soil conditions permit the cultivation of a wide range of crops, not only tropical varieties but also many originating in semitropical and temperate zones. Until the late 1950s, however, the major emphasis in agriculture was on rice and, secondarily, on rubber, which together accounted for over half the value of all commodity exports. Other crops regularly grown included maize, cassava, potatoes, yams, beans, sugarcane, fruit, cotton, and various oilseeds, but all were supplementary and intended basically for domestic use. Historically, Thailand's independent status had kept it from being saddled with a colonial plantation economy, in which two or three principal crops were produced for world markets or for the imperial power. Agricultural production, however, had been strongly influenced by the West after the Bowring Treaty of 1855 with Britain, which resulted in crop diversification. Accordingly, when new market conditions-- increased world demand, higher prices, and developing domestic industry--arose during the 1960s and 1970s, Thailand's independent small farmers responded by expanding substantially the output of many secondary crops. The flexibility of the Thai farmer was evidenced by an unprecedented shift from rice production to other crops by a considerable number of households. In other cases, many farmers continued to produce rice for subsistence purposes while expanding their activities to grow market-oriented upland crops. In the mid-1980s, major export crops included not only rice and rubber but also maize, cassava, sugarcane, mung beans, tobacco, and sorghum. Other important crops in which major production increases also had been made were pineapples, peanuts, cashew nuts, soybeans, bananas, sesame, coconuts, cotton, kapok, and castor beans.
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.
Cassava, a root crop from which tapioca is made, was introduced in about 1935. The tubers may also be boiled and eaten as a vegetable or ground into flour. An important food in many tropical subsistence economies, cassava had never been significant in Thailand in the past because of the abundance of rice. Cassava developed into an important export item in the 1950s, and production continued through the 1970s and 1980s as external demand increased. Thai output of cassava root in 1984 was more than 19 million tons, second only to Brazil in world production. The main growing areas were Chon Buri and Rayong provinces, southeast of Bangkok, but substantial quantities were also grown in parts of the Northeast. In 1986 Thailand signed a 4-year tapioca trade agreement with the EEC calling for export of 21 million tons of tapioca during the 1987-91 period.
In 1901 British planters introduced rubber trees into the Malay Peninsula, where the soils and climatic conditions were highly suited to rubber cultivation. In Thailand early government restrictions on foreign investment led to development of the industry by local smallholders, usually subsistence rice farmers who were able to start rubber tree stands on the relatively abundant free land in the area. Land under rubber cultivation expanded rapidly in the 1930s, consisting mainly of smallholdings controlled by Chinese, Thai, and Thai Malays rather than large, European-owned plantations, as in other Asian countries. Thailand had about 1.6 million hectares in rubber in the mid-1970s, of which about 10 percent were located in an area along the Gulf of Thailand southeast of Bangkok. Of the 500,000 holdings in the early 1980s, about 150,000 were under 2.5 hectares in size, and another 300,000 were under 10 hectares. The remaining larger holdings were operated more as expanded smallholdings than as plantations. Production was increasing in the early 1980s and had reached about 830,000 tons in 1987. An extensive replanting program, in which old tree stock was replaced with new high-yield varieties, had reportedly been carried out in about half the planted area by the mid-1980s, significantly increasing the potential for expanded production.
