TABLE 58. RELATION OF TYPE OF SEED TO YIELD ON 292 FRANKLIN AND CLINTON COUNTY 



FARMS IN 1913 



not agree with the experiments previously cited for the factor of whole as 

 compared with cut seed. The apparent discrepancy cannot be attributed 

 to differences in amount of seed and in value of manure and fertilizer, as 

 these factors average approximately the same for both groups. 



A rather striking effect of the rate of planting is shown in table 58, 

 where the types of seed are arranged according to the average yields 

 obtained from each. In fact, thruout these studies of the relation of type 

 of seed to yield, it has been shown that those types which required the 

 highest rate of planting were productive of the highest average yields. 



RELATION OF AMOUNT OF SEED TO YIELD 



The very marked effect of rate of planting on yield has been shown in the 

 previous discussions of the effect of manure and fertilizer and of size of 

 seed piece. A majority of the very large number of tests which have been 

 conducted to determine the optimum number of bushels per acre to plant, 

 indicate that in this country too little seed is generally planted, under 

 average conditions. In contrast to this, the large yields obtained by 

 European growers, who commonly plant from 30 to 40 bushels of seed per 

 acre, are often cited. It does not follow, however, that similar rates of_ 

 planting in New York would be productive of such yields. Land, labor, 

 and climatic conditions in northern Europe are such that high rates of 

 planting are not only possible but also profitable. As shown by the major- 

 ity of experiments testing this factor, the most profitable rate of planting
