GRAIN-SORGHUM EXPERIMENTS IN THE PANHANDLE OF TEXAS. 85 
time has been, only 12.7 bushels, exactly the same as that of C. I. No. 
261. In addition, it was able to make a yield of only 35.2 bushels in 
1915, so it may be dropped from further consideration. 
The two selections, C. I. Nos. 413 and 424, are fairly promising. 
They are about 10 days later than C. I. No. 171, but about equal to 
‘itin height. Both have been grown only during the last seven years, 
and their average acre yields in that time have been 16.8 and 18.6 
bushels, respectively. The yield of No. 171 was 19.8 bushels in 
the same period, or 1.2 bushels more than that of No. 424. In 1915 
the yield of No. 413 was 48.6 bushels and that of No. 424 was 38.9 
bushels, the former exceeding the yield of No. 171 by 2 bushels in 
that year. Valley, C. I. No. 309, a variety about two weeks later 
and a little taller than No. 171, was grown during the first six years 
and produced an average acre yield of 18.4 bushels compared with 
19.5 bushels from No. 171 in the same years. Nos. 261 and 293 
yielded in the same years 12 and 12.7 bushels, respectively. 
COMPARATIVE YIELDS OF ALL THE KAOLIANGS. 
A survey of the comparative yields given in Table XXXVI shows 
that varieties of the brown-seeded kaoliangs have made the best 
average yields in both the 7-year and 9-year periods. In the 7-year 
period three brown-seeded sorts outyield the Barchet (blackhull), 
which in turn outyields the Mukden (white). In the 9-year period 
two of the high-yielding brown-kerneled sorts are not present, but 
the other three varieties maintain the same relative rank as before. 
TasLE XXXVI.—Annual and average acre yields of grain of the leading varieties and 
races in each of the subgroups of the kaoliang group of grain sorghums grown at the 
Amarillo Cereal Field Station in most or all of the nine years from 1908 to 1916, inclusive.
