PLATE I 
Photograph of plat 8 in the commercial fertilizer series in 1917 on University Farm 
(see Table IX). Marquis on the left and hybrid on the right. This plat had received 
acid phosphate at the rate of 1,000 pounds per acre in 1916 but none in 1917. It 
had received sodium nitrate at the rate of 1,000 pounds per acre in 1917. Note the 
very severe lodging. This is characteristic of the effect of nitrogen on University 
Farm. Note also the badly shriveled seed from the Marquis. This variety showed 
60 per cent of stem rust, and the yield was 15.8 bushels per acre. Compare with 
Plates 2 and 3.
