SUDAN GRASS AND RELATED PLANTS. 8 
Pilot Point, Tex., in the same year. None of these later importations 
had any appreciable effect on the spread of Sudan grass in the United 
States, because practically all of the seed distributed by the United 
States Department of Agriculture to State agricultural experiment 
stations in 1912 and to farmers in 1913 originated in the importation 
of 1909 grown in the increase plats at the Chillicothe (Tex.) Field Sta- 
tion in that and the following years (fig. 2). The Texas Agricultural 
Experiment Station 
obtained a consider- 
able quantity of the 
seed from the Depart- 
ment of Agriculture 
in 1913 and distrib- 
uted it to farmers in 
the State, enthusias- 
tically urging its 
propagation. 
The success of the 
Sudan grass was im- 
mediate and phenom- 
enal, and in order to 
encourage its propa- 
gation the Office of 
Forage-Crop Investi- 
gations has carried on 
a great many testsin 
cooperation with the 
State agricultural ex- 
periment stations. 
It is the purpose of 
this bulletin to de- 
scribe the results of 
these tests more fully 
than was possible in 
the former publica- 
tion, Farmers’ Bulle- 
tin 1126, in order to 
establish definitely the status of Sudan grass in different sections 
of the United States and to furnish a more complete basis for the 
recommendations given in the bulletin mentioned. Other grass sor- 
ghums closely related to Sudan grass are considered also and their 
probable value indicated.

DESCRIPTION AND BOTANICAL RELATIONSHIPS. 
Sudan grass is an annual hay plant belonging to the sorghum
