FARM MANAGEMENT PRACTICE OF CHESTER COUNTY, PA. 73 
RELATION OF TENURE TO YIELD OF CROPS. 
The first line of Table XL gives the average yields of the crops 
- grown in this area on farms operated by their owners, the second line 
yields on the tenant farms taken as a whole. As is to be expected, 
yields on the farms operated by their owners are slightly larger on 
the average than those operated by tenants, but the difference is not 
great. The last two lines of the table give a comparison of the yields 
on farms operated by cash tenants and those operated by share ten- 
ants. Except in the case of silage, the yields are in all cases larger 
on the farms of share tenants, the difference probably being due to 
the greater amount of control the landlord retains of the business in 
the case of share-rented farms.

The average yield of corn on the share-rented farms is actually 
larger than it is on the owned farms, the yield of hay being ap- 
proximately the same, while in the case of the other crops the owners 
have more or less the advantage in the matter of yield. 
QUALITY OF BUSINESS. 
A very important factor of efficiency in farming is the quality 
of the business. This is indicated by the yield per acre, the income 
per animal unit, work units accomplished per individual employed, 
etc. 
YIELD PER ACRE. 
- Table XLI shows the average yield per acre of the principal crops 
on the 378 farms operated by their owners, by size of farm. Some 
of these yields are very high, while others are low. The average 
: yield of corn was 65.3 bushels per acre, which is far above the average 
for any of the corn-belt States as a whole, and there are few localities 
in any State that exceed this. The yield of silage is correspondingly 
high, being 13.1 tons per acre, or an average of 1 ton for each 5 
bushels of corn. The season of 1911 was very favorable to the corn 
crop, and this yield is somewhat above the average for this locality. 
The yield of wheat is satisfactory when compared with State averages
