EXPERIMENTS WITH EMMER, SPELT, AND EINKOKN.

CULTURAL EXPERIMENTS. 
Owing to the relative unimportance of emmer and spelt inmost 
sections, these crops usually have not been included in cultural, 
tillage, and rotation experiments. The results of a few experiments 
conducted at various stations to determine the best rates, dates, 
depths, and methods of seeding emmer are presented on the following 
pages. 
RATE-OF-SEEDING EXPERIMENTS. 
RESULTS WITH WINTER EMMER. 
Results of experiments on rates of seeding with Black Winter 
(C. I. 2337) emmer covering from one to three years have been 
obtained at Amarillo, Tex., Nephi, Utah, and Archer, Wyo., in 
cooperative experiments of the Office of Cereal Investigations. The 
results obtained are shown in Table 51. The highest average yields 
were from the plats sown at the rate of 6 pecks per acre, but the 
5-peck sowing produced the highest net yields at Amarillo. 
It usually is difficult to obtain a good stand of Black Winter emmer 
The spikelets are so large that they feed through the grain drill only 
with difficulty. With the drill adjusted as for sowing oats, emmer 
will be sown at nearly the same rate as oats. From the results at the 
three stations it appears that Black Winter emmer should be sown 
at the rate of about 6 pecks per acre.

RESULTS WITH SPRING EMMER. 
The results of rate-of-seeding experiments with Vernal (White 
I Spring) emmer, conducted at four stations in the United States and 
one station in Canada, are shown in Table 52. At Manhattan, Kans., 
during one season, a sowing of 84 pounds per acre produced the 
highest yield, but the sowing of 56 pounds returned almost the same 
net yield. At North Platte, Nebr., and Eureka, S. Dak., the seeding 
of 6 pecks per acre produced the highest yields. At Archer, Wyo., 
the 3-peck seeding was the most productive, but the difference in
