BROOM-COMST EXPERIMENTS AT WOODWARD, OKLAHOMA.

Oklahoma Dwarf. These names are mostly local and do not repre- 

 sent different varieties. 



The Dwarf broom corn used in the varietal experiment included 

 three different lots in the first three years, from 1914 to 1916, in- 

 clusive. In 1917 three more lots were added, making a total of six 

 grown in that year. One was added in 1918, which made seven for 

 that year. In all, a total of seven different lots and 22 plats were 

 grown in the 5-year period from 1914 to 1918, inclusive. These lots 

 were obtained from different sources, most of them widely separated. 



C. I. No. 442 was obtained from a grower at Sterling, Kan., in 

 1911, and has been grown at the Amarillo (Tex.) Field Station since

that time. Plants of this strain are shown in figure 5. C. I. No. 535 

 is the result of a selection made by the senior writer in 1912 from a 

 crop grown at the Amarillo station that year from bulk seed obtained 

 from a grower near Amarillo, Tex. The crop from which this selec- 

 tion was made was evidently a mixture of Standard and Dwarf 

 varieties, as it was quite variable in height and type of brush. 



C. I. No. 557 was obtained from a grower at Elk City, Okla., in 

 1914. He had been growing this strain in large quantities for a 

 number of years, distributing the seed commercially under the name 

 Evergreen Dwarf. It is a good variety, well adapted to dry lands, 

 which produce a high yield of good brush under average conditions.
