POTATOES. 



In this study 26 potato-growing districts were visited and 918 

 farmers were interviewed (Table 8). The acreage of potatoes rep- 

 resented was as follows: Early potatoes (southern districts), 11,487; 

 midsummer potatoes (central coastal plain), 5,598; late crop pota- 

 toes in Maine, New York, Michigan, and Wisconsin, 6,373; in Iowa 

 and Minnesota, 4,763; in Colorado, 2,210; in Washington, 782 — 

 total, 31,213 acres. 1 



There was a wide range in normal man-labor and horse-labor 

 requirements. It would be natural to look for some uniformity in 

 the man-labor and horse-labor requirements within a given region, 

 more particularly if the conditions under which the crop was grown 

 happened to be fairly uniform and the yields were approximately 

 the same. In the region producing the midsummer crop of potatoes 

 the amount of man labor utilized in marketing was much the same 

 for all districts. However, the central New Jersey district, reporting 

 the highest yield per acre, had the minimum labor requirement. 



Farm manure applications varied from 7 to 12 loads per acre in 

 the late potato districts and three of the midsummer districts. 

 Commercial fertilizers were used in larger quantities in the early 

 and midsummer districts than in the late producing areas. The 

 Maine districts may be taken as exceptions from this general state- 

 ment. Comparatively light applications were made in the three 



1 The enterprise records which were used in compiling the information on potatoes were obtained during 

 the years 1912-1913 by H. H. Clark and L. L. Corbett. A report prepared by E. H. Thomson in connec- 

 tion with this cost survey was available for reference in compiling Table VIII.
