In the alternating rows of wheat, the actual number of 
plants per row were in the ratio of 100:37, while in the 
three inside rows of the five row plats the ratio was 100:34. 
The number of culms per plant in the alternating thick and 
thin rows were in the ratio of 100:123, while in the center 
three rows of the five row plats the ratio was 100:195. 
In the case of the oats, the actual number of plants per 
row were in the ratio of 100:51, both for the alternating 
rows and for the three inside rows of the five-row blocks. 
The number of culms per plant in the alternating thick and 
Uiin rows were in the ratio of 100:135, while for the center 
three rows of the five-row plats the ratio was 100:168.
