It will be noted from this table that the observed and cor- 

 rected yields are very nearly parallel in the majority of these 

 pure lines. The reason for this is that the soil in the 19 15 field 

 was much more uniform than that used in the preceding year. 

 The following discussion unless specifically stated will be based 

 on the corrected yield. 



The corrected yield of individual plots ranged from 91.9 to 

 62.5 bushels. The highest average yield was for No. 340 and 

 No. 355, viz., 83.6 bushels each. The lowest average yield was 

 75.1 bushels in Line No. 336. The average yield of all the lines 

 was 78.6 bushels per acre. This was about 8 bushels per acre 

 less than in 1914. 



The average yield of straw per acre was 3622 pounds or 

 nearly 300 pounds less than in 1914. 



The average weight per measured bushel was 37.5 pounds, 

 or 2.4 pounds less than in 1914.
