Hogue’s Yellow Dent was grown in this test during the first three years 
and Nebraska White Prize thereafter. 
the alternating hills of one, three, and five plants yielded 3.0 
bushels less. 
These data suggest that corn plants, of the larger varieties at 
least, draw upon the soil fertility and moisture for such a dis- 
tance that considerable irregularity in stand may exist without 
markedly affecting the yield.
