: 356 REPORT OF THE FARM SUPERINTENDENT OF THE 
The range of yield from the five sections of each plat is as 
follows, expressed in per cent of difference of sound corn: 
Between 49.9 per cent and 97.1 per cent on the most variable 
plat, B; and 16.7 per cent and 20.1 per cent on the least 
variable plat, M, according as the difference is computed on the 
highest or lowest yield as a basis. 
With so even a stand of crop, and so little difference as has 
been shown in yield, both from the above test of fertilizers and in 
cultivation tests on the same field, one is safe in the assertion 
that these wide apart results are very largely due to variations in 
the fertility of the various sections of the plats and the relative 
capacity of those areas to produce a crop. 
FERTILIZER EXPERIMENT WITH CORN. 
An experiment with fertilizers for corn has been planned to 
continue several years on the same plats. The object is to com- 
pare the effects of different elements and combinations for corn 
when applied year after year on the same soil. In preparing the 
sround for this experiment, in order to overcome the force of 
differences in the previous fertilizing and cropping, as well as to 
start the experiment with a well-fed crop, a liberal dressing of 
barnyard manure was spread over all the plats to be used. 
This dressing was well harrowed in and the ground fitted for 
the crop, working all plats alike, except where muck and barn- 
yard manure is to be annually applied on C 17, D19, E 19 and 
F 20, an extra amount of cultivation was needed to cover this 
‘extra application for this season. 
The corn was planted May 23, and fertilizers sown the same 
day, save that on E 18, which was sown next day. The kind and 
amount of fertilizers applied are given in the following table, 
with the stand of corn just before harvesting. There were five 
or six kernels of seed dropped per hill, and when well started it 
was thinned to four stalks. The corn was cultivated and hand- 
hoed twice, and quite late in the season cleaned of weeds again 
by hand.
