S.P.I. No. 36935 in 1916.

It is apparent from Table 4 that Red Amber, a variety which oc- 
cupies a leading position among the sorgos at Hays, Kans., ranks 
very low in yield of forage at Chillicothe. Sumac sorgo, on the other 
hand, made good yields of both fodder and seed. (See fig. 15.) 
The experiments show that it is entitled to the high regard in which 
it is held by farmers, and no other variety, with the possible exception 
of Honey, seems worthy of replacing it in their favor. (Fig. 10.) 
Honey makes a yield of forage nearly 50 per cent larger than that of 
Sumac, at Chillicothe but does not mature seed regularly. White 
African is another variety that made a good showing at Chillicothe. 
During the seven years it was grown, this variety produced 12 per 
cent more forage and 64 per cent more seed than Siimac. 
Among the grain sorghums Dwarf Yellow milo and feterita have 
produced the highest average grain yields. The grain yield of 
feterita (F. C. I. No. 811) slightly exceeded that of Dwarf milo, but 
the latter variety made the most forage. Feterita is favored for late 
planting and as an insurance crop against complete failure from 
drought. The true value of Spur feterita has not yet been deter- 
mined, but its leafiness and relatively high forage value combined 
with its good grain yield make it a promising crop. (Fig. 11.) It 
was 12 days later in maturing than ordinary feterita during the test 
period of 1919 to 1921 and therefore would not fit in so well as a 
drought-evading crop. 
Red kafir has made better yields than either the Blackhull or the 
Pink variety. It is not grown so extensively as Blackhull, however, 
possibly because the market prefers a white-seeded kafir. Dwarf 
hegari, though it made good yields of both forage and seed, is not 
valued highly, because it is so variable in its habits of growth and 
in its reactions to climatic conditions.
