The principal wheat and Indian corn producing districts lie in the provinces of Santa Fe, Buenos Aires, Cordoba and Entre Rios, and the average yield of wheat throughout the country is about 12 bushels to the acre.
The rapid development of the foreign trade of the republic since 1881 is due to settled internal conditions and to the prime necessity to the commercial world of many Argentine products, such as beef, mutton, hides, wool, wheat and Indian corn.
