DATE-OF-SEEDING EXPERIMENTS. 
RESULTS WITH WINTER EMMER. 
Date-of -seeding experiments with Black Winter (C. I. No. 2337) 
emmer have been conducted at Amarillo, Tex., and Nephi, Utah. 
The results obtained are shown in Table 53. At Amarillo, which is 
located in the Panhandle section of Texas, the average yields for five 
years were practically the same from the second sowing made between 
October 14 and October 19 and the third sowing made between 
November 1 and November 7. These yields were but little higher 
than those from the first sowing made between September 1 and 
October 5. Four-year results show a slight advantage for the first 
sowing. At Nephi, Utah, which is about 300 miles farther north 
than Amarillo and at an altitude of nearly 6,000 feet, the average 
yield was slightly higher from the sowings made on October 1 than 
from those made earlier or later. In general, winter emmer should 
be sown at about the same time as winter wheat.

RESULTS WITH SPRING EMMER. 
The yields obtained in date-of-seeding experiments with Vernal 
(White Spring) emmer at North Platte, Nebr., Highmore, S. Dak., 
and Brandon, Manitoba, are shown in Table 54. The data from 
North Platte are taken from Bulletin No. 172 of the Nebraska Agri- 
cultural Experiment Station (73). Most of the yields from High- 
more were published in Bulletin 179 of the South Dakota Agricultural 
Experiment Station (10) and those from Brandon, Manitoba, in the 
annual report of the Dominion experimentalist for 1902 (41). 
At North Platte and Highmore the earliest sowings produced the 
highest average yields, although later sowings are ahead in some 
years at North Platte. Similar results have been obtained with the 
other spring grains at those stations. At Brandon, Manitoba, the 
results are for one year only and therefore are not conclusive. The 
latest seeding, on May 27, produced the highest yield, and the earliest 
seeding, on May 6, the second highest yield.
