Alstroum spelt produced an average yield of 1,897 pounds per acre 
and Red Winter yielded practically the same. Tennessee Winter 
barley gave an average yield of 1,548 pounds and Winter Turf oats 
1,577 pounds per acre. Black Winter emmer yielded considerably 
less than these crops. Here, as at Arlington, winter spelt is much 
more productive than either barley or oats. At both stations, how- 
ever, the best varieties of winter wheat yielded more than winter 
spelt when allowance is made for 25 per cent of hulls in the spelt. 
RESULTS IN THE MISSISSIPPI AND ST. LAWRENCE VALLEYS. 
The subhumid area extends from the Great Plains to the eastern 
border of the Mississippi Valley and from the head of the Mississippi 
River east to the Atlantic coast. The area includes the region desig- 
nated as the Corn Belt, the prairie sections north and south of the 
Corn Belt region, the Great Lakes region, and the St. Lawrence 
Valley. The precipitation in most of the area ranges from 20 to 30 
inches, but reaches 40 inches in the extreme eastern and southern 
portions. 
Winter wheat is the leading small grain in the southern half of 
the area and spring wheat in the northern portion. Oats is the lead- 
ing small grain for feed in the Corn Belt and is important in the 
northern portion of the prairie area. Barley is of importance in 
this area only in Minnesota, in Wisconsin, in the eastern portions of 
the Dakotas, and in Canada. 
Only a few experiments with emmer and spelt have been reported 
in the prairie or subhumid area. Corn is the principal feed grain in 
all except the northern portion, so that barley and oats are grown 
largely because they fit into the rotation scheme. A few preliminary 
trials in the Corn Belt States indicated the unsuitability of emmer 
in comparison with oats, so that long-continued data are not avail- 
able. In the northern portion of the prairie area the results with 
emmer have been more favorable, and more experiments with that 
crop have. been reported. The results obtained in the subhumid area 
are here given. 
RESULTS AT DENTON, TEX. 
Emmer and spelt were grown for three years at Texas substation 
No. 6, at Denton. The yields, as reported by Cory US) in Bulletin 
No. 199 of the Texas Agricultural Experiment Station, are shown in 
Table 7. Black Winter emmer gave an average yield of 888 pounds 
per acre, Red Winter spelt 1,080 pounds, Tennessee Winter barley 
1 ,538 pounds, and Red Rustproof oats 1 ,354 pounds per acre. Emmer 
and spelt are not as productive as barley and oats in this section of 
Texas.
