DETASSELING GOOD VERSUS POOR STALKS IN THE SEED PLAT 
During the eleven year period 1907-1917, an experiment was 
conducted to determine whether a profitable increase in produc- 
tion might be had by selecting the seed corn from a seed plat in 
which the apparently inferior plants had been detasseled to 
insure against the use of seed which had been fertilized by 
plants of inferior appearance. 
In 1900, two isolation seed plats were planted to Hogue’s 
Yellow Dent corn. In the one plat the poorest one-half of the 
plants were detasseled and in the other the best one-half of the 
plants were detasseled. The following } T ear these two lots of 
seed were continued in separate isolation seed plats bv merely 
shelling together a large number of well-developed ears from 
each plat. Both plats were again subjected to the same treat- 
ment as that of the previous year, and so thruout the entire 
period of eleven years. Thus there was opportunity for cumula- 
tive effect to assert itself. 
Each year these two lots of seed were compared with each 
other and with the original Hogue’s Yellow Dent corn in a 
separate yield test. During the last seven years of the test, a 
cross between the two lots of seed was also included. The re- 
sults are given in Table 43.
