Altho there is no proof in table 2 that the yield increases with an increase 

 in elevation, there is a slight indication that this may be true. The farms 

 located at 50 to 100 feet elevation had a lower yield than those at the 

 lowest elevation, partly because they received less seed and fertilizer 

 than any other group. Furthermore, the farms at the lowest elevation 

 received slightly more than the average amount of seed and fertilizer per 

 acre. It is improbable, however, that the wide difference in yield between 

 the two groups at the lowest elevations was due entirely to differences 

 in amount of seed and fertilizer. There may have been some basic reason 

 why the 87 growers at the 50-to-100-feet elevation used the least seed 

 and the least fertilizer, which would account in part for the lower yield. 

 No such reason is apparent, however, from the data at hand. 



Influence of elevation in Steuben County 



The average elevation of the farms visited in Steuben County is greater 

 than in any other of the regions concerned in this survey, it being 1659.2 

 feet. The elevation varies from 1200 to 2100 feet, a range of 900 feet, 

 and within this range there is a considerable variation in the soil types, 

 as is shown later in table 13 (page 1770). A summary of the average 

 yields obtained at various elevations is given in table 3 :

A general tendency for yields to decrease as elevation increases is 

 ndicated by table 3. This is counter to the expected influence of altitude, 

 and may be explained by the fact that the soil at the higher altitudes of
