 RICE CROP OF COUNTRIES NAMED, 1902-1906 



[Mostly cleaned rice. China, which is omitted, has a roughly estimated crop of 50,000,000,000 to 

 60,000,000,000 pounds. Other omitted countries are Afghanistan, Algeria, Brazil, Colombia, 

 Federated Malay States, Madagascar, Persia, Russia (Asiatic), Trinidad and Tobago, Turkey 

 (Asiatic and European), Venezuela, and a few other countries of small production.] 



they doubtless approximate the truth as a general rule, and are more trust- 

 worthy, especially for purposes of comparison, than the state estimates. 



It should be kept in mind that certain crops, such as wheat, are now quite 

 regularly fertilized in some of the Eastern and East Central states. 



Comparison of crop yields in different states is most significant when the 

 acreage is also comparable. In 1907 the average yield of wheat per acre was 

 23 bushels in Vermont and only 1 1 bushels in Kansas ; but Vermont raised one 

 thousand acres and Kansas raised six million acres, and on many thousand 

 acres the Kansas yield may have exceeded 30 bushels per acre. In 1905 the 

 average yield of corn per acre was 42.7 bushels in Connecticut and only 39.8 

 bushels in Illinois; but Connecticut raised only 55,595 acres of corn, while 

 Champaign County, Illinois, raised some 200,000 acres of corn, which made an 

 average yield of 65 bushels per acre. 



South Carolina is authentically credited with having produced 239 bushels 

 of air-dry corn on one acre of land in one season, but the average yield for the 

 state for the 44 years, 1866 to 1909, is 10 bushels per acre. Even the average 

 yield of corn for the United States has varied from 30.8 bushels per acre, in 

 1872, to 16.7 bushels, in 1901 ; and if these records were interchanged the average 

 yield would become the same for two successive 2o-year periods, 25.0 bushels 

 per acre.
