than 95 per cent of the heads were erect. The proportion of erect 

 heads is influenced by the vigor of the plants at and after heading 

 time. A low percentage of erect heads is correlated with good rains 

 in the first half of August in 1908 and 1910, but not in 1914, when 

 a drought in July had weakened the plants too much to permit 

 response to the improved conditions. 



Milo has made a very good average yield, 22.7 bushels of 58 

 pounds each per acre, in the 9-year period under consideration. 

 The average is based on the yields from no less than 107 plats in 

 the nine years. Table VII contains the annual and average acre 

 yields of all lots grown. According to the figures in Tables VI and 

 VII, the lowest average annual acre yields have been in 1913, 6 

 bushels in 1909, and 7 bushels in 1916. The highest have been 61.4 

 bushels in 1915, 35.4 in 1908, and 32.3 bushels in 1911. The nine 

 annual yields may be classified as one failure, three poor, two fair, 

 two good, and one excellent. This probably is not far from what 

 may be expected to occur in any period of similar duration. The 

 9-year average acre yields of the three lots grown during that 

 period were 22.9, 22.4, and 20.5 bushels, respectively.
