200 STORRS AGRICULTURAL EXPERIMENT STATION. 
the different plots manifested itself throughout the season. In 
general the crops on the plots having no nitrogen in the fertil- 
izer were pale yellow in color and more backward in growth 
than those on the plots with nitrogen. A comparison of the 
results from plot D with those from plots E and F, as given in 
Table 48 below, suggests that in this particular experiment the 
corn seemed to be benefited most by the combination of nitro- 
gen and phosphoric acid in the fertilizer. The table shows, 
however, that the largest yields of corn in 1898 were obtained 
from plots X and Y, which had the stable manure with and 
without phosphoric acid. This is the third time that corn has 
come into the rotation of crops in this series of experiments; 
and, as will be seen by comparing the results for the three 
years, given in Table 50, in two of the three years the largest 
yield has been obtained from plot Y, with the largest amount 
of stable manure, while in the other year the yield from this 
plot was essentially the same as that from the plot G, with 
the mixed minerals and nitrogen.
