Table VIII shows that a selection of Dwarf broom corn (C. I. No. 

 597) made the highest average yield of good brush in the 2-year 

 period, with the Acme variety taking second place, while several 

 other Dwarf selections are close competitors for third place. In the 

 5-year period, the Acme and the Dwarf (C. I. No. 535) tie for first 

 place, with an average yield of 392 pounds of good brush. The

Fig. 7. — Diagram showing the annual and average percentage of good brush in the total 

 yield produced by the Standard, Acme, and Dwarf broom corn grown in varietal 

 experiments at the Woodward Field Station during the 5-year period from 1914 to 

 1918, inclusive. 



Dwarf (C. I. No. 557), with an average yield of 387 pounds, or only 

 5 pounds less, takes a close second place, and the Standard (C. I. 

 No. 556) takes third place, with an average yield of 331 pounds in 

 this period. The 5-year average yield of the Standard, Acme, and 

 Dwarf varieties is shown graphically in figure 6.
