SORGHUM EXPERIMENTS OX THE GREAT PLAINS.

isfactory at Hays, Kans., both in yield and quality of grain. A num- 
ber of other miscellaneous varieties, such as Progressive kafir. Duallo, 
and Early Buff durra, were tried for one or more years and discarded 
because of their lodging habit and various other objectionable 
qualities. i 
CHILLICOTHE, TEX. 
The experiments at this point for 1913 and 1914 were located on a 
small tract of land adjoining the city of Chillicothe on the northwest. 
In 1915 the work was moved to a tract of 100 acres 4^ miles south 
and 1 mile west of Chillicothe. This land was purchased early in 
1916 by the State of Texas and designated Texas Substation No. 12. 
From the beginning the forage-crop experiments have been conducted 
under a cooperative agreement with the Texas Agricultural Experi- 
ment Station. 7

Weather records have not been collected at Chillicothe for a very 
long time, but Table 1 shows that the rainfall was a little above 
normal during the 9-year period of these experiments. The distribu- 
tion of the rainfall was unsuited to the sorghums, however, in at least 
three years— 1913, 1917, and 1918. 
The station is 1,406 feet above sea level, and the soil and climatic 
conditions are representative of a large area in north-central Texas. 
The most disadvantageous feature of the climate in growing sorghums 
is the dry period so often encountered in July and August. (See fig. 3 
' From 1913 to 1917, inclusive, the experiments were in charge of R. W. Edwards, then connected with 
the Office of Forage-Crop Investigations. Since Mr. Edwards' resignation, February 25, 191S, the work 
has been directed by A. B. Cron. Work began at Chillicothe in 1905, and the results of the earlier years, 
1905 to 1914. are presented in Bulletin 202 of the Texas Agricultural Experiment Station (6). Prior to 1913 
the experiments were conducted under a plan different from that followed in the later years and are not 
included in this bulletin.
