Vernal eninier produced an average yield of 1.611 pounds per acre, 
which exceeded the yield of Improved Ligowa oats, but was con- 
siderably less than the yield of Manchuria barley. Barley appears 
to be the most productive of the three crops at Morris.

RESULTS AT GRAND RAPIDS, MINN. 
Vernal emmer was grown at Grand Rapids. Minn., in 1919. 1920. 
and 1921. The experiments were conducted independently by the 
Minnesota Agricultural Experiment Station, and the yields obtained 
in 1919 were given by Bergh (3) in the report of the Grand Rapids 
substation for that year. The yields obtained in 1920 and 1921 
were furnished by Prof. A. C. Arny. of the Minnesota Agricultural 
Experiment Station. 
As shown in Table 14. both barley and oats gave average yields 
distinctly higher than those of emmer at Grand Rapids. The yield 
of Vernal emmer was satisfactory in only one of the three years in 
which the crop was grown.

RESULTS AT CROOKSTON, MLNN. 
Emmer was grown during eight years at Crookston. Minn., in the 
Red River Valley. The experiments were conducted independently 
by the Minnesota Agricultural Experiment Station. The yields 
were reported in part by Selvig {%6) in the report of the Northwest 
Experiment Farm. The yields obtained in 1920 and 1921 were 
furnished by Prof. A. C. Amy. of the Minnesota Agricultural Ex- 
periment Station. The results at Crookston are shown in Table 15, 
Vernal emmer produced a 7-year average yield of 1.403 pounds 
per acre, exceeding both barley and oats in two of the years tested. 
In the same seven years the average yields of barley and oats were 
1.643 and 1.636 pounds per acre, respectively. Thus emmer is 
inferior in productiveness to both barley and oats at Crookston.
