The green revolution has greatly increased the wheat supply in the developing world. The experiences of Mexico, India, Pakistan, Turkey, and Argentina are reviewed here. Governments of these countries, except Argentina, used procurement programs and input subsidies to maintain high profits for wheat production as long as domestic production substituted for imports. As these countries achieved wheat self-sufficiency, incentives for wheat production versus other crops were reduced. In contrast, Argentina taxed wheat exports and protected its high-cost fertilizer industry. Argentina increased wheat output by adopting semi-dwarf varieties double-cropped with soybeans using a small amount of fertilizer.
