Another field test was made at Shelbyville, Ind., in 1922, in coop¬ 
eration with a commercial canning company. This test was con¬ 
ducted on a larger scale and bulk seed was used instead of that 
selected from individual ears. The corn used was a strain of Country 
Gentleman which had been grown and selected under local con¬ 
ditions for four years. It had become fairly well acclimated in this 
time and was of good type for the variety. A sufficient number of 
large and small kernels were hand picked to plant a half acre each, 
and in addition to these plots one of equal size was planted with un¬ 
graded seed from the same source to serve as a basis for comparison. 
The soil was a very rich, uniform, black loam. It was well drained 
and in a fine state of cultivation. The com was drilled with a two- 
horse corn planter, the smallest plates being used. 
When the corn came up the stand was very good. The stalks in 
the plot planted with large kernals were uniform in vigor, size, and 
color. There were practically no small or slender stalks in the whole 
plot; they were vigorous and stocky, and dark green in color. 
The stalks in the plot planted with small seed were much shorter 
and slenderer than those from the large kernels. They were fairly 
uniform in color, but varied somewhat in size. (Note the similarity 
of the following observations to the data given in Table III.) 
A wide range of variation was evident in the plot planted with the 
ungraded bulk seed. The stalks ranged in size from the small, slender 
types to the large, stocky ones, with various intermediate types 
between. 
At tasseling time the stalks from the large kernels came into full 
tassel evenly and about five days in advance of those from the small 
ones; in fact, it was possible to distinguish these rows a long distance 
from the field by tins earlier and more uniform development. The 
stalks from the small kernels were distinctly smaller and later at this 
time; they were tasseling irregularly and only about 20 per cent had 
reached the tassel stage. 
The plot planted with the ungraded seed was also very irregular. 
It was composed of a mixture of stalks varying in size and maturity 
from those in full tassel to those in which the tassels were just begin¬ 
ning to form. 
HARVEST DATA 
Outstanding differences were noted in the plots at harvest time. 
These consisted chiefly in time and evenness of maturity and size of 
stalks and yields. The plants from the large seeds were larger and 
more uniform in maturity than any in the series, about 95 per cent 
having reached maturity at the same time. They were well developed 
and the kernels were of fair size and deep. A good many of the 
stalks bore two full-sized ears. 
The stalks from the small kernels were shorter and slenderer than 
those from the large ones and were uneven in maturity. A few were 
as .mature as those in the plot from the large seed, some had quite 
recently come into full silk, but the majority were just passing out 
of the premilk stage, that is to say, they were about five days later 
than the plants from the large seed. 
The plot planted with ungraded seed was also very irregular in 
the size of its stalks and the maturity of its ears. The latter ranged
