1 No varietal experiments were conducted in 1920. 
For the 13 years from 1910 to 1919, inclusive, and in 1921, 1922, 
and 1923, according to the data presented in Table 9, the Kichland 
outyielded the Albion by nearly 8 bushels to the acre. This decided 
advantage in favor of Richland is not paralleled by the results on 
Iowa farms. However, the farm tests cover only two years, and the 
data, therefore, can not be considered as conclusive. 
EXPEKIMENTS ON IOWA FARMS 
During the 3^ears 1916 and 1917 the Iowa Agricultural Experiment 
Station distributed seed of both Albion and Richland to 54 farmers 
for trial. A summary of the yields obtained from these experiments 
is shown in Table 10.

In the 54 trials in which Richland and Albion oats were grown 
in adjacent acre plats, the Richland has exceeded the Albion by an 
average yield of only 1.78 bushels. These average results indicate 
that Richland when grown on ordinary prairie soil probably will 
not produce so well as on the more fertile soils of the Iowa Agri- 
cultural Experiment Station Farm. Apparently, on the average 
soils of the State these two varieties may be expected to give almost 
identical yields.
