GRAIN-SORGHUM EXPERIMENTS IN OKLAHOMA.

has never been very high. Valley kaoliang has averaged 15.9 bushels 
per acre, while the Manchu averaged but 13.4 bushels. The total 
crop yields have been in proportion to the grain yields. 
The annual and average acre yields of the kaoliangs are shown in 
Table 12, together with those of shallu and certain miscellaneous 
sorghums.

THE SHALLU GROUP. 
One selection of shallu has been included in these experiments for 
the full 8-year period. Shallu has been retained in the varietal 
experiments, as it is frequently exploited 7 under a variety of names, 
and reliable data are desirable. It has proved to be of little value 
under the conditions at the Woodward Field Station. The data for 
shallu are presented in Table 13, and a head of this sorghum is shown 
in Plate IV. Figure 1. 
In grain yields shallu has varied from 0.3 bushel in 1918 to 28.7 
bushels in 1921, with an average yield of 15.4 bushels to the acre, as 
compared with 26.3 bushels for Sunrise kafir and 21.8 bushels for 
Dwarf Yellow milo. The stalks are dry and pithy and practically 
valueless as forage. 
MISCELLANEOUS SORGHUMS. 
Three sorghums which do not belong to any of the main groups 
of grain sorghums were included in the experiments. These are 
darso 8 (C. I. Xo. 615), Sehrock sorghum 9 (C. I. No. 616), and 
Dwarf hegari 9 (C. I. No. 620). Darso and Sehrock sorghums, both of
