been cut as early as August 10 with a very slightly smaller yield. 
The second growth on these two plats was over :'> feet high when 
killed by frost on November 4. 
The remaining 8 plats were harvested for seed on September 20 
and yielded an average of 23 pound.- each, or 460 pounds per acre. 
Practically no seed was lost by shattering. The second growth in 
these plats was about 1 foot high when killed by frost on November 4. 
A late seeding was made on August 7 in rows, and this was 48 
inches high and fully headed when killed by frost on November 4. 
There can be no doubt that by seeding not later than June 1 two 
full cuttings of Sudan grass for hay can be obtained each season in

Virginia. The grass has shown much stronger growth in cultivated 
rows than when broadcasted, but it .-till remains to be determined 
which method is most desirable. 
The seed grown at Arlington Farm in 1012 weighed 3G pounds per 
bushel. 
Mixtures of Sudan grass with cowpeas and with soy beans were 
also tested (fig. 5). A one-tenth acre plat was broadcasted on June 
11 with 3 pounds of Early Black cowpeas and 2 pounds of Sudan 
grass. This was cut for hay on September 6 when the Sudan grass 
was in bloom and the first pods of the cowpeas were fully grown. 
The grass was 6 to 8 feet high and the cowpea vines were of about an 
equal length. The plat yielded 9-2.") pounds of cured hay. about one-
