Freezing Injury of Seed Corn 
87 
As an average for the four years, the long, slender, smooth 
type yielded 58.8 bushels per acre, which is 0.7 bushel more than 
the original corn. 7,1 bushels more than the large rough ears, 
1.7 bushels mor? than the short rough ears, and 2.1 bushels 
more than the short, smooth ears. One may conclude that this 
long, slender, smooth sype possesses highly satisfactory yielding 
qualities which, coupled with its superior germinative ability, 
makes it a very suitable type to grow. This type of ear is 
gaining greater popularity among corn men of the State, altho 
the old prejudice for deep rough ears with a high shelling per- 
centage has been rather persistent. 
EFFECT OF UNUNIFORM STAND ON YIELD 
An investigation was made in 1915 and 1916 to determine 
the effect of varied distribution of plants upon the yield of 
corn. The number of plants per acre was the same in all cases, 
but the number of plants in adjacent hills differed. The pur- 
pose was twofold: (1) To learn the effect of variation in stand 
caused by mechanical variation in dropping by corn planters, 
when corn with perfect germination is planted. (2) To learn 
what result might be expected from planting corn, only part of 
which will grow, but for which the rate of planting has been 
calculated to seed the desired number of sound kernels per acre. 
The tests were made in duplicate o-row blocks and equal num- 
bers of each type of hill were harvested within each plat. 
The methods of distribution compared were : 
(1) All hills with uniformly 3 plants. 
(2) Alternating hills with 2 and I plants. 
(3) Alternating hills with 1, 3, and 5 plants. 
(I) Alternating hills with 1, 2, 3, I, and 5 plants. The 
results are given in Table 34. The average yield for the three
