SWEET SUDAN GRASS 
For productivity, convenience of planting and certainty of crop 
of nutritious forage, Sudan Grass has proven to be foremost for sup- 
plemental or emergency pasture or hay crop over a wide area of the 
U.S., particularly in central and southern states, since its introduc- 
tion less than 85 years ago, even though when introduced it was 
neither sweet or juicy. 
Like many other plants under constant study and experiment 
new and better varieties and types of Sudan are being produced by 
crossing, back crossing and selection. One of the latest and most prom- 
ising in many respects is the new 
SWEET SUDAN GRASS 
This new variety is a develop- 
ment resulting from _ several 
years breeding work by the 
Texas Agricultural Experiment 
Station in cooperation with the 
Bureau of Plant Industry, U. S. 
Department of Agriculture. This 
year (1944) is the first time 
enough seed were available to 
plant acreage of this new variety 
to produce seed in commercial 
quantities. The supply that will 
be available for planting in 1945 
is limited and will doubtless be 
booked up long before time to 
plant.

THE FOLLOWING ARE SOME PERTINENT REASONS FOR THE USE OF THIS NEW SWEET 
SUDAN GRASS IN AREAS WHEREVER SUDAN GRASS GROWS SUCCESSFULLY: 
1. It is sweet, juicy and more palatable to livestock. This was demonstrated consistently during the years 
the breeding and selection were progressing. When planted side by side with Common Sudan, the 
cattle kept the Sweet Sudan grazed to the ground, while the Common Sudan was grazed down to the 
height of about one foot. In all cases the Sweet Sudan was eaten first. 
2. Sweet Sudan enjoys the great advantage of having seed with glumes or hulls that are sienna or 
reddish brown in color. This enables a farmer to readily detect the presence of Johnson Grass seed, 
if any, in his Sudan Grass seed. Johnson Grass seed has glumes or hulls that are black, brownish 
black or blackish straw in color and such seeds are easily seen with the naked eye in Sweet Sudan 
Grass seed. No farmer need hesitate to plant Sudan for fear of Johnson Grass now, if he uses 
Sweet Sudan.
