206 STORRS AGRICULTURAL EXPERIMENT STATION. 
fertilizers as the larger plots had received in the earlier experi- 
ments on grass. The plan of the experiment included:-a series 
of ten plots, two to be without fertilizers, and eight to have a 
fixed quantity, in each case, of ‘‘ mixed minerals’’—dissolved 
bone-black and muriate of potash. Of the eight fertilized plots, 
two were to have no nitrogen and six were to receive different 
kinds and amounts of nitrogen. On three of these last the 
nitrogen was applied in the form of nitrate of soda, supplying 
nitrogen at the rate of 25, 50 and 75 pounds per acre respect- 
ively, and the other three were supplied with sulphate of 
ammonia furnishing nitrogen at the same rates of 25, 50 and 
75 pounds per acre. 
Owing to the smallness of the plots it cannot be expected 
that the experiments will prove as valuable as regards the effect’ 
of fertilizers on yields as might be obtained on larger plots. It 
was thought, however, that the most important part of the 
experiment would be the effects of fertilizers on the composi- 
tion of the plants, and that the results would be nearly as 
valuable from smaller plots as from larger, and a greater num- 
ber of crops could thus be experimented upon. 
EXPERIMENTS ON CORN. 
This experiment was undertaken for the purpose of studying 
the effect of nitrogenous fertilizers on the yield and composition 
of two varieties of corn which differed quite widely in compo- 
sition at the start; these two varieties to be grown for a period 
of years, with the same kinds and amounts of fertilizers. "The 
seed was to be saved from the crop of each plot each year and 
planted again on the same plot the following year. ‘This is the 
second year of the experiment. One variety of corn—the white 
flint—was chosen because it contained relatively large quanti- 
ties of protein (13.0 per cent.) in the dry matter, while the 
other variety—a yellow flint—had been grown upon poor soil 
for many years, and contained relatively small quantities of 
protein (11.2 per cent.) in the dry matter. The two varieties 
were grown at opposite ends of the original large plots and 
were about 300 feet apart. The first season (1895) the seed of 
the two kinds mixed slightly, but care was taken to select the 
distinct kinds for seed in 1896. In that year the two kinds were 
planted about a week apart, and thus mixing was prevented.
