SUDAN GRASS AND RELATED PLANTS. 16 
having a rainfall of 20’to 40 inches and a mean temperature during 
the growing season of 80° to 90° F., climatic conditions very similar 
to those in our southern Great Plains, where Sudan grass has done so 
well. 
SUDAN GRASS IN OTHER COUNTRIES. 
Since its introduction by the United States Department of Agricul- 
ture, Sudan grass has been tested in many parts of the world. It has, 
perhaps, been most successful in Australia, where it is being grown 
at the different experiment stations, and is recommended highly, 
especially in New South Wales (3). It has done well where tested 
in Brazil and Argentina (fig. 12), and no doubt will become a valued 
forage crop in the stock-producing sections of South America.

Brazil. 
The Philippine Islands, Hawaii, and Porto Rico all report success 
with Sudan grass, and in Cuba it is highly prized as forage (12). 
Although it is not adapted to the climate of Canada, good crops of it 
have been grown in southern Alberta. Sudan grass is sure to prove 
valuable in all semitropical regions and in the warmer parts of the 
temperate zones. 
SOIL RELATIONS. 
FERTILITY. 
Sudan grass thrives best, of course, in a good soil. Rich clay 
loams produce the best growth, but it makes better yields on poor 
soils than most hay crops. A good many farmers are now using it 
as a supplementary pasture on poor hill lands in the dry summer
