Cooperative Tests of Corn Varieties

whole State or for any considerable part of it. This bulletin is written 

 with the purpose of presenting the most important results obtained in 

 the several localities. The best variety of corn, or even the question of 

 choice between flint and dent varieties as classes, must be determined 

 locally ; but a study of the results given herewith will indicate that a few of 

 the varieties tested have shown adaptability in several different places.

In order to present to the best advantage the experimental results obtained, 

 the author has summarized the results for those localities in which the 

 most important tests were made for more than one year; for variety tests 

 made but once in a given place, the results are either reported separately 

 or combined in tabular form with those from other places. 



Experiments at Ithaca 



Variety tests were made in 1909 and 19 10 on the Dunkirk clay loam 



soil of the Cornell University farms. The field used for the first test was 



in a good state of cultivation; a much less fertile field was used for the 



second test. Drought interfered with growth of the corn both seasons.
