120 MAINS AGRICUI/fURAE EXPERIMENT STATION. I916. 



From this table (4) it will be noted first that the yields of 

 grain are absolutely much higher than in 1913. Individual 

 plots gave an observed yield as high as 120 bushels per acre. 

 The reason for this is partly in the better soil in the 19 14 field, 

 but more especially in the very favorable season. While there 

 was abundant moisture well distributed throughout the' growing 

 season, nevertheless there were no flooding rains or heavy wind 

 storms to damage the crops. As a matter of fact, the seasonal 

 conditions were almost ideal. The yields obtained in 1914 

 would seem to represent almost a maximum production. 



The average observed yield for the several pure lines ranged 

 from 108.8 bushels in No. 340 to 62.2 bushels in No. 104. Thus 

 showing a range of over 46 bushels between the highest and the 

 lowest yielding lines. 



The corrected average yield per acre varied from 105.3 

 bushels in No. 355 to 65.7 bushels in No. 104. The range is 

 about 6 bushels less than in the case of the observed yields. 



The average corrected yield of all the pure lines tested was 

 86.9 bushels. This is nearly 22 bushels per acre better than the 

 average of these pure lines in 1913. 



The highest observed yield among the 22 commercial varie- 

 ties tested in 1914 was 105 bushels for the Minnesota 26. This 

 was the only commercial variety with an observed yield of over 

 100 bushels. On the other hand, six of the pure line varieties 

 gave an average observed yield of over 100 bushels. Regarding 

 the. corrected yields, which is undoubtedly a fairer basis of 

 comparing the varieties, the highest yield in a commercial vari- 

 ety was 96.1 bushels shown by the Lincoln variety. There were 

 six pure lines which gave an average corrected yield of over 96 

 bushels. More detailed comparison of the yield of commercial 

 varieties and pure lines will be given after the results of the 

 191 5 test have been considered. 



The average yield of straw per acre varied from 5308 pounds 

 to 3090 with an average of 3902 pounds. Comparing this with 

 the average weight of straw in 19 13 (Table 3) it is seen that 

 the straw yield in 1914 is nearly 1200 pounds per acre greater 

 than in the preceding year. 



The weight per measured bushel was not obtained for all of 

 the lines. For the sixteen lines in which it was determined the
