A number of interesting points come out of these tables. 

 Among these are the following: 



1. Taking the Type I corn first it appears that on the aver- 

 age over the whole plot 21 out of every 10 1 ears fit to be 

 used for seed at all were of such superior quality as to be placed 

 in the Ai class. This is a high ratio as compared with the 

 seed which the packers ordinarily distribute to the farmer. ■ 



2. The same fact is brought out in a more striking way by 

 considering the weight of shelled corn produced on the different 

 classes of ears. On the average 24.6 per cent, by weight of the 

 shelled corn of seed quality came from ears graded as Ai. 



3. As would be expected from the above relations there 

 was only a small proportion of the total crop unfit for seed. 

 Taking the average of all the rows only 15.2 per cent, of the 

 total yield of shelled corn was borne on nubbins or poor ears 

 which could not be classed as good seed. 



4. The average yield in bushels per acre of dried and shelled 

 seed corn for all rows was 35.29. Considering the fact that 

 this is for a stand of only one stalk to a hill it can only be re- 

 garded as a very good yield. The distribution of the yields for 

 each of the 100 rows is shown graphically in Fig. 223.
