| Abstract |
Throughout the developing world during the past decade, maize and wheat production has advanced as never before. In Mexico, for example, average yields of wheat progressed from about 2,200 kg/ha in 1960 to 3,200 in 1969-70. Maize production was increased from about six million tons in 1960 to almost nine million in 1968, years with comparable rainfall. With high yielding varieties and production technology imported from Mexico, Pakistan raised its wheat production from 4.6 million tons in 1964-65 to about 8.4 million tons in 1969-70. Similarly, India increased production from 12 million tons in 1965, to over 20 million in 1970. These phenomenal successes have been referred to as the Green Revolution and have stimulated other countries to greater activity with hopes of becoming self sufficient in their basic food grains. |
