GRAIN-SORGHUM EXPERIMENTS IN THE PANHANDLE OF TEXAS. 87 
It has been grown at Amarillo in all the nine years except 1909. 
The data resulting are presented in Table XXXVII. It has proved 
itself quite unfitted for the dry-land conditions obtaining in: the 
Texas Panhandle, as is fully shown also in the publications cited. 
Its germination has been poor in nearly all. years. It is tall and 
‘very late in maturing, frequently lodging in autumn storms and 
often failing to ripen. For these reasons the yields have been very 
low. In 1910, 1913, and 1916 it produced no grain at all. The 
production of suckers has always been high, and where adapted it is 
more likely to prove of value for forage than for grain 
COMPARATIVE YIELDS OF ALL THE GROUPS. 
The annual and average acre yields of the leading races in each 
variety of each group of grain sorghums are shown in Table 
Fig. 12.—Diagram showing the annual and average acre yields, in 58-pound bushels, of standard milo, 
- Dwarf milo, and feterita at the Amarillo Cereal Field Station during the 9-year period from 1908 to 1916, 
inclusive. : 
XXXVIII. The average yields are given first for the 7-year period, 
from 1910 to 1916, inclusive, in order to compare a few selections 
grown only in those years. The average yields in the full 9-year 
_ period from 1908 to 1916, inclusive, are given for all selections grown 
that long. 
It will be noted from this table that Dwarf milo made the highest 
average yield of any subgroup in both the 7-year and the 9-year 
periods. Therefore it takes first place in grain production among 
the grain-sorghum groups. The best selection of Dwarf milo yielded 
an average of 27.2 bushels annually in the 7-year period and 27.1 
bushels in the 9-year period. The average yield of Dwarf milo in 
both periods is approximately 5 bushels more than the average yield 
of any other variety. Figure 12 shows graphically the annual and 
average yields of milo, Dwarf milo, and feterita in the 9-year period 
from 1908 to 1916, inclusive, at Amarillo, Tex.
