Thailand devotes some 70 percent of its cropland to growing rice. Its annual yield, after milling, totals four to five million tons. Of this, more than a million tons is exported, accounting for almost half the country's out side revenue. New dams and canals are steadily added to older ones threading the plains. Boats riding on them seem to sail across green and gold fields. Villages and thatch-roofed farm homes border the canals, as along highways. Today agriculture specialists also carry on research in seeds, fertilizers, and pest con trol to further increase the rice yield. The Thai are also giving attention to more diver sified crops, such as corn, castor beans, soy beans, and cassava, and to double cropping where water is available.
