that of milo. In no year has the average yield of all lots of the Alba 

 variety exceeded the average yield of all lots of standard milo. Like- 

 wise, the highest yielding Alba has never equaled the highest yield- 

 ing milo. In 1915, the year of bumper yields, however, the average 

 yield of the two lots of Alba equaled the average yield of the five lots 

 oi milo, being 61.8 and 61.4 bushels per acre, respectively. In short, 

 A.lba milo is almost identical with milo in all its adaptations, but so 

 far is slightly below milo in yield. The annual and average yields of 

 one strain are compared with those of the other milos and durras in 

 Table XVIII.

FETERITA. 



Feterita ^ is a variety of the milo group introduced from the 

 British-Egyptian Sudan. It is similar to milo in most of the char- 

 acters of the stalks and leaves. In height it averages about 5 feet 

 under Panhandle conditions, or about 1 foot taller than milo. The 

 tiead or spike is more elongated, elliptical rather than ovate in out- 

 Line, somewhat less compact than that of milo, and always erect. 

 The seeds are a chalky white, or sometimes bluish white, rather than 

 a yellowish white or pale buff. The seeds also are softer than those 

 of milo, and hence more Ukely to decay in a cold, wet soil. A plat 

 of feterita grown at Amarillo, Tex., in 1915, is shown in figure 7. 



One importation was received in time to be included in the experi- 

 ments in the spring of 1908, while a second was added in 1914. Only 

 12 plats have been grown, therefore, in the 9-year period. The 

 results obtained are shown in Table XII. 



The total length of the growing period of feterita has varied greatly 

 in the nine years. The average is about 107 days. In general, the 

 responses of feterita have been about the same as those of milo to
