EXPERIMENTS WITH EMMER, SPELT, AND EINKORN. 
33 
Vernal emmer was grown in each of the 14 years and produced an 
average yield of 762 pounds per acre. During the same period 
Hannchen barley produced 1,477 pounds and Kherson oats 1,075 
pounds per acre. ■ Khapli emmer yielded slightly more than the 
Vernal variety during the two } r ears it was grown. 
At Akron and in the surrounding portion of northeastern Colorado 
the winters are too severe for winter emmer or winter spelt to be 
successfully grown. Spring emmer can be grown, but it is much less 
productive than the best varieties of barley and oats. 
Table 26. — Yields of four varieties of emmer, two varieties of spelt, and one variety each 
of barley and oats grown at Akron, Colo., in some or all of the 14 years from 1908 to 
1921, inclusive.

RESULTS AT NORTH PLATTE, NEBR. 
The experiments at the North Platte substation of the Nebraska 
Agricultural Experiment Station were conducted independently by 
the State. The results shown in Table 27 were taken from Nebraska 
Agricultural Experiment Station Bulletins Nos. 118, 135, and 172, 
published by Snyder and Burr (53, 54) and by Zook (73). During 
the 10-year period from 1909 to 1918 a combination date-of-seeding 
experiment was conducted with spring wheat, oats, barley, and
