CAUSES FOR VARIATIONS IX LABOR REQUIREMENTS FOR FODDER CORN 
The higher Yielding fields require more labor for harYesting. This 
is especially true in case of shocking. 
Farm 8 has high labor requirements for cutting for the reason 
mentioned in the silage discussion. 
On farms 5 and 12, haYing the highest labor requirements for 
shocking, the fields shocked were from one-half to 1^ miles from the 
farmstead. Rain interference increased the number of trips to these 
fields by a considerable amount, thus emphasizing this handicap. 
MATERIAL REQUIREMENTS FOR CORN 
The aYerage quantity of seed per acre for checked corn on all farms 
for the three years was 8.7 pounds. It Yaried from 7.2 pounds to 
10.5 pounds. This checked corn was spaced 3 feet 6 inches or 3 feet 
8 inches, and three or four kernels were planted per hill. The aYerage 
rate of seeding for drilled corn was 14.7 pounds, with a range from 
8.9 pounds to 24.9 pounds. This wide range was due to the fact that 
some corn was planted thinly so that full-sized ears would be formed, 
whereas most of it was planted thickly so that there would be no 
mature ears. The aYerage quantity of twine used per acre was 3.6 
pounds. The least quantity was 1.5 pounds and the largest 6.4 
pounds. The range was largely due to differences in Yield. Twine 
requirements for drilled corn are usually much higher than for 
checked corn, because the drilled corn is planted more thickly. 
STANDARD REQUIREMENTS PER ACRE FOR CORN PRODUCTION IN SOUTHWESTERN 
MINNESOTA 
The standard requirements shown in Table 12 are suggested for 
corn production. As has been stated, they represent the accom- 
plishment of those farmers who handle their labor most efficiently as 
measured by their ability to perform the various operations with the 
Least hours of labor. These standard requirements furnish a standard 
of attainment for all farmers to use as their guide. The seed require-
