MANAGEMENT OF GENERAL EARMS IN OREGON. 
13 
There were 90 farms on which no clover seed ra as sold. On 28 
farms 6.8 per cent, and on 26 farms 32.4 per cent, of the receipts 
were from the sale of clover seed. The average farm incomes of 
these three groups were, respectively, 5.40, 7.78, and 8.87 of the capital 
invested. Thus 26 farms which received an average of 32.4 per 
cent of their receipts from the sale of clover seed were 1.64 times as 
efficient as the 90 farms that sold no clover seed.

Table IX shows the comparative value and yield of oats, wheat, 
barley, and corn per acre in the Willamette Valley. The yields per 
acre are averages computed from the United States Census Reports 
for the years 1880, 1890, 1899, and 1909. The values per acre are 
based upon the average prices of these crops at Portland, Oreg., for 
the 10-year period, 1906 to 1915, inclusive. The price of barley is used 
in computing the value of corn, it being assumed that these two crops 
are approximately equal in value, pound for pound. 
Table IX. — Comparative value and yield of oats, wheat, barley, and corn per acre for the 
nine counties of the Willamette Valley, Oreg. ( U. S. Census Reports 1880, 1890, 1899,

From the standpoint of value as stock feed, 912 pounds of oats 
are not to be compared with 1,134 pounds of wheat, 1,286 pounds of 
barley, or 1,506 pounds of corn. It will also be seen that there is a 
marked difference in the cash value of these crops, oats being worth 
$12.14, wheat $16.53, barley $16.15, and corn $18.92 per acre.

Table X shows the comparative value and yield per acre of oats 
and wheat on the 68 clay farms, and of oats, wheat, and barley on 
the 144 silt loam farms for the year 1912. The values per acre in 
this table are also based on the average prices at Portland, Oreg., 
for 10 years. Of the 68 clay farms, only one reported barley, and 
barley is therefore not considered under the clay type of soil.
