Although rice was by far the most important food crop, corn was the major source of calories for about 18 million people, especially in Jawa Timur and Jawa Tengah provinces. About 75 percent of corn production was consumed as a staple food source. Corn cultivation was concentrated on Java and Madura under a variety of conditions, but most frequently on tegalan, or rain-fed land without the system of dikes characteristic of floodable sawah. Other food crops included cassava, sweet potatoes, peanuts, and soybeans.
