Photograph of plat 26 of the commercial fertilizer series in 1917 on University Farm

potassium chlorid at the rate of 1,000 pounds per acre in 1916 but no fertilizer in 1917. 
The rust infection was 32 per cent on Marquis and 7 per cent on the hybrid. The 
yield on Marquis was 33.2 bushels per acre. Note the plump kernels of Marquis and 
compare with those shown in Plate 1.
