SPRING WHEAT. 



Beside the uniform trial plots there were eight 2-acre plots of Marquis wheat 

 grown under different conditions. The following table indicates the yield per acre 

 from each of these plots : — 



The average yield on 8 acres of fallow in 1912 was 26 bushels 40 pounds, and in 

 1013 was 38 bushels 59 pounds. The average on 6 acres of stubble in 1912 was 15 

 bushels 24 pounds and in 1913 was 22 bushels 27 pounds. This stubble had been fall 

 ploughed. The yield per acre on 2 acres of corn ground in 1912 was 33 bushels and 

 in 1913 was 52 bushels 11 pounds. Tlie average under all conditions on 1(3 acres in 

 191 j! was 23 bushels 12 pounds, and in 1913 was 34 bushels 25 pounds. It is rather 

 significant that the average yield on corn stubble is higher than the average yield for 

 the same years on summer-fallow. 



The order of the rotation is : Summer-fallow manured in the fall ; corn well 

 worked throughout the season; and corn stubble spring ploughed and sown to wheat.
