The record of five years from Williston includes three years of 

 heavy and two of very low production. When averaged for the five 

 years the results do not show a wide variation in yields by different 

 tillage methods. The yield of oats has been higher each year except 

 1910 by both spring and fall plowing when the crop followed wheat
