GRAIN-SORGHUM EXPERIMENTS IN THE PANHANDLE OF TEXAS. 
dl 
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 0 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 durmeg that 
period were 22.9, 22.4, and 20.5 bushels, respectively. 
TasLe VIJ.—Annual and average acre yields of all lots of standard milo grown at the 
Amarillo Cereal Field Station during periods of varying length in the nine years from 
1908 to 1916, inclusive. 
[In the statement of yields per acre the bushel is rated at 58 pounds. ]
