NEED OF STUDY OF CORN IN SCHOOLS. 
- For a considerable number of years more attention has been given 
by farmers to the production and improvement of corn than to any 
other grain or general farm crop, yet for no 10-year period has the 
average corn yield of the United States exceeded 28 bushels per acre. 
No State has averaged for any year over 54 bushels per acre, yet in 
practically every section of the United States yields of more than 
100 bushels per acre have been produced. With the rapid spread of 
the work of boys’ clubs the need of the study of corn in the schools 
has come to be better appreciated. The purpose of this bulletin is 
to furnish lessons for developing the real educational value of this 
study.
