The average height of Dwarf milo in all 90 plats in all nine years 
was 3 feet, compared with an average of 4 feet for milo. There was 
an enormous variation in average height from year to year. For 
instance, in 1916 the average height was only 2.3 feet, and in 1912 
but 2.6 feet. In 1915, however, under the influence of abundantg 
rainfall, it rose to 4.5 feet, and in 1911 to 4.8 feet. The average 
height of 1.7 feet, recorded in 1913, included many stalks which bore 
no heads and therefore had not attained full height. 
The most important character of Dwarf milo is its outstanding 
ability to produce good yields, as shown in Tables IX and XVIII. 
The average acre yield from all the 90 plats grown in the nine years 
has been 26.2 bushels. Under the same conditions, the average acre 
yield from 107 plats of milo was 22.7 bushels. The lowest average 
yield recorded, except the complete failure of 1913, is 8.6 bushels, in 
1916. The highest is 68.4 bushels, in 1915. In the same years milo. 
yielded 7 and 61.4 bushels, respectively. The yields of this variety 
obtained during the nine years of the experiment may be classified 
as follows: One failure, two poor, three fair, two good, and one 
superexcellent. | 
TaBLE IX.—Annual and average acre yields of all lots of Dwarf milo grown at the 
Amarillo Cereal Field Station during periods of varying length in the nine years from
