For convenience in tabulating, the results for Sumac sorgo from 
1913 to 1917 are grouped with those of Freed sorghum and feterita. 
because these varieties were included in the experiments for the same 
period. The results obtained with these three varieties are incon- 
clusive, and no definite recommendation can be made from them. 
There is no consistent difference in the yields of either forage or grain 
attributable to the differing row spaces. A decision as to the best 
rate of seeding would have to be made in this case on the effect of row 
space on the size of the heads and quality of the forage, rather than 
on yields.
