Although the yield of forage is small and of rather poor quality, the 
variety may be used to good advantage for late seeding when "other 
crops have failed or when for any reason the farmer finds himself as 
late as July 15 in danger of a feed shortage. A few farmers have 
used Freed advantageously in mixture with Sudan grass and sorgo 
as a hay crop. Freed sorghum improves the quality of the hay by 
the added quantity of grain which it supplies. 
Darso sorghum is a new variety developed and named by the 
Oklahoma Agricultural Experiment Station (1). It is early, dwarf, 
leafy, and sweet stemmed, with large, rather loose but erect heads. 
Darso produced 14 per cent less forage but 11 per cent more grain 
than Dwarf kafir at Chillicothe, Tex. (Fig. 20.) At all other field 
stations in the southern plains it has compared favorably in yields 
with the other varieties of grain sorghums. Darso is a reliable grain 
producer south of Kansas, particularly in adverse seasons. The

characteristic that interferes more than anything else in its becoming 
generally popular pertains to the feeding value of the seed, which 
resembles that of the sorgos. Feeding tests at the Oklahoma station 
indicated that the seed of Darso had a slightly lower feeding value 
than that of kafir when measured by gains in liesh. Recent palata- 
bility tests at the Kansas Agricultural Experiment Station indicate 
that with hogs Darso seed ranks as about equal to sorgo seed in 
palatability." For forage alone Darso can not compete with the 
sorgos, because the yields are much less than those of Sumac and 
Orange. 
Schrock sorghum has attained more or less prominence, but tests 
have proved that it has no special merit either as a grain or forage 
variety. Compared with the standard varieties, it did best at 
Tucumcari, N. Mex.,but there it is exceeded in forage value by Sumac 
sorgo and in grain yields by Dwarf hegari and Darso. Schrock made
