Only about 150,000 hectares were planted with major crops other than rice in 1990, an increase from around 80,000 hectares in 1980. Principal nonrice crops include cardamom--sometimes considered a forestry product--coffee, corn, cotton, fruit, mung beans, peanuts, soybeans, sugarcane, sweet potatoes, tobacco, and vegetables. The only crop produced for export in substantial quantities is coffee. Although the total area planted to these crops is small relative to the area planted to rice, it increased from 10 % of total cropped area in 1980 to about 18 % in 1990. Although the increase in part reflects the drop in rice production during the drought years, it also demonstrates some success in the government's push to diversify crops. Yields for all the major crops except coffee, vegetables, and cardamom--for which some figures are only available from 1986--increased gradually between 1980 and 1990, most notably corn , fruit, peanuts,and mung beans.contempt increasing agricultural output, Laos is still an importer of food, heavily dependent on food aid.
