Maize, with its multitude of food, feed, and industrial uses, its high genetic yield potential, and its wide range of adaptation, will experience increasing demand in the decades ahead. Population growth and income changes are the key influences. During the 1990s, world maize demand is expected to grow at about 2.6 percent per year. Most of the increase will come from the Third World. To meet this demand, maize production must increase by approximately 123 million tons to 600 million tons by the end of the century (Table 11.1).
