EXPERIMENTS WITH BROOM CORN. 
The experiments’ with broom corn at the Woodward Field Sta- 
tion were started in 1914. The results of five years of work are now 
available. While this may be too short a period from which to draw 
final conclusions, it is thought that the results thus far obtained are 
worthy of publication. Much interest is shown in the crop at this 
time and a large number of inquiries are being received for informa- 
tion with regard to varietal adaptation, the best time to sow, and the 
rate of seeding which will give best results in both yield and quality 
of brush. The results obtained at Woodward and reported herein 
1These experiments were conducted in cooperation with the Office of Dry-Land Agri- 
culture of the Bureau of Plant Industry. Mr. HE: F. Chilcott, of that office, is superin- 
tendent of the station. Credit is hereby given him for his hearty cooperation and assist- 
ance in conducting these experiments. The senior writer was in charge of this work at 
the station during the seasons of 1914 and 1915. The junior writer was appointed 
assistant agriculturist on October 5, 1915, and conducted the experiments at the station 
in the seasons of 1916, 1917, and 1918.
