GRAIN-SORGHUM EXPERIMENTS IN OKLAHOMA.

inner coat. This seed color is similar to that of dwarf hegari and 
certain white-seeded kaoliangs, any of which when crossed with any 
ordinary white-seeded variety, as white-seeded kafirs, white milo, 
white durra. or shallu, gives a brown-seeded progeny in the F x gen- 
eration. Feterita seeds are softer than those of milo and are more 
susceptible to decay in cool, damp soils. 
One selection of feterita (C. I. No. 182) has been included in these 
experiments for the entire eight years. A second selection was grown 
for two years and discarded as of no greater value than C. I. Xo. 182. 
Spur feterita 4 was received in 1919 and has been included in the 
experiments since that date. The agronomic data and results ob- 
tained from feterita are presented in Table 7.

Station during the eight-year period from 1914 to 1921, inclusive.

The total length of growing period of feterita has varied from 87 
days in 1918 to 142 days in 1917, the average for the 8 years being 
104 days, as compared with 118 days for the milos. The vegetative 
period of feterita has been shorter than that of milo, averaging 69 
days, as compared with 82 days for milo. The fruiting or ripening 
period has been of practically the same duration as for milo, 35 and 
36 days, respectively.
