GKAIlSr-SOEGHUM EXPERIMENTS IN THE PANHANDLE OF TEXAS. 87 



It has been grown at AmariUo 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 fuUy 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 autunm 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 aU. The 

 production of suckers has always been high, and where adapted it is 

 more Ukely to prove of value for forage than for grain 



Comparative Yields of All the Groups. 



The aimual 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 mdo in 

 both periods is approximately 5 bushels more than the average yield 

 of any other variety. Figure 12 shows graphically the aimual and 

 average yields of mUo, Dwarf milo, and feterita in the 9-year period 

 from 1908 to 1916, inclusive, at AmariUo, Tex.
