: Yields for 1914 interpolated. (Eight-year average yield of X : 8-year average yield of Sumac sorgo : : 
■ Id of X : 1914 yield of Sumac sorgo.) 
- Dwarf kafir was used as a check because it has been grown longest at Chillicothe. It is a dwarf solec- 
rom Blackhull kafir, S. P. I. Xo. 17569, and is well adapted to the conditions at Cuillk 
Table 5 presents the yields of less important varieties of sorghum 
each of which is compared with a cheek variety ha vim: about the 
same length of growing season. In order to understand properly 
the percentage yield- of forage given for the first four varieties in 
this table if is well to remember that Red Amber, the check, pro- 
duce- only 57 per cent as much forage as Sumac. Although the 
Whooper and Clubhead sorgos are credited with more forage than 
Red Amber, their yields are much Less than that of Sumac, the 
standard sorgo variety of Texas and Oklahoma.
