TABLE 15. PER CENT or POTATO LAND FALL- OR SPRING-PLOWED IN THE AREAS SURVEYED 



The average dates of spring plowing in 1912 for Long Island and for 

 Steuben County were April 3 and April 29, respectively. The average 

 dates of spring plowing in 1913 for Monroe County and for Franklin and 

 Clinton Counties were May 15 and May 12, respectively. No speculation 

 as to the reason for the greater proportion of fall plowing in Franklin and 

 Clinton Counties is offered, but it is presumed to be due as much to weather 

 conditions for the year as to labor competition with work on other crops. 

 The comparative yields on land plowed at the different seasons in Franklin 

 and Clinton Counties are shown in table 16: 



TABLE 16. 



RELATION OF TIME or PLOWING TO YIELD ON 300 FRANKLIN AND CLINTON 

 COUNTY FARMS IN 1913 



In view of the fact that about a bushel more of seed and a slightly higher 

 value of manure and fertilizer were used on the fall-plowed land, the dif- 

 ference in yield of 10.5 bushels per acre in favor of fall plowing may not be 

 entirely due to a difference in the time of plowing. There is no indication 

 that fall plowing is commoner on the larger potato acreages, since the 

 average acreage was the same in all three groups.
