BULLETIN 1271, U. S. DEPARTMENT OF AGRICULTURE 
Labor requirements for cultivation are lowest on large, well- 
shaped fields. On farms 3, 7, and 13, which, used the least number of 
man and horse hours for cultivating 1 acre one time over with a 1-row 
cultivator, the average size of field was 26 acres and the average length 
92 rods. On farms 8, 15, and 22, with high labor requirements, the 
average size of field was 8*4 acres and the average length 52 rods. 
The labor requirements on farm 15 are further increased by the 
distance of the fields from the farmstead. More than half of the 
cornland was over a mile from the farmstead. 
On Farm 1, although most of the operations were performed with 
less labor than on the majority of the farms, the man-labor require- 
ment per acre for husking was one of the highest. This work was 
performed by members of the family and included woman and child 
labor, whereas on most farms the husking was done by experienced 
man labor. 
Except for husking, there was no marked relation between yield 
and labor requirements. In general, the labor requirements for husk- 
ing increased with increased yields. This tendency is especially 
evident from a comparison of the average requirements for the three 
years. 
The effect on labor requirements of repeating an operation is quite 
apparent in case of cultivating. On farm 9 the man-labor required 
for one cultivation was one of the lowest in the group, but the large 
number of cultivations, 4.84, brings the total requirement for cul- 
tivating among the highest. The same increase is apparent in a less 
degree in harrowing and disking. 
LABOR REQUIREMENTS FOR SILAGE CORN 
The labor requirements for silage corn are presented in Tables 
8 and 9. Since the operations on the corn crop prior to harvesting are 
the same regardless of how it is to be harvested, this labor is included 
as one item in these tables. This is taken from Tables 6 and 7 and 
includes all labor prior to husking. It has already been considered 
in the discussion of those tables. The item of ''filling silo" includes 
all labor involved in hauling the corn to the silo, filling the silo, pack- 
ing the silage, and any incidental operations.
